Crossover and Speaker Settings in Relation to Bass Management



Most, if not all AV amps and receivers now incorporate some form of bass management. In many instances this management allows a user to determine the point at which lower frequencies are sent to the speakers and subwoofer via crossover settings.

This topic isn't intended as a tutorial for specific models of AV amp, but is intended to give some general guidance and dispel some of the misconceptions associated with the 'LARGE' and 'SMALL' speaker settings found on AV amps and receivers.



The Basics

Not all speakers are capable of handling the full range of frequencies associated with audio reproduction. The range of frequencies a speaker will reproduce (lowest to highest) is in many cases limited. The optimal range is 20-20,000Hz – this is generally accepted as being the range of human hearing. Speakers that can handle the full optimal range are referred to as "full range". Limited range speakers are far more common than full range units. While limited range speakers will more often than not be capable of handling the full gamut of high frequencies associated with treble, they're unlikely to be able to reproduce the lowest audible frequencies associated with bass. Some full range speakers go beyond what is accepted as the range of human hearing, but this is beyond the scope of this post and has little relevance to the topic being addressed in its context.

Crossovers are filters, made up of coils and capacitors, that direct specific frequency ranges to the appropriate speaker components such as the drive units associated with bass and treble (the low and high frequencies). This means that the drivers do not strain to reproduce notes out of their intended range and beyond the speaker's capabilities.

Most speakers incorporate passive crossovers, designed for the components within that speaker, such as the drive units etc.. A passive crossover is placed post amplification and the full range of frequencies are present in the amplified audio signal the passive crossover has to filter. During the filtering, if the crossover finds frequencies beyond the speaker's frequency range, it discards them. The discarded frequencies are lost forever and will not be passed on through to the drive units. These lost frequencies will therefore not be reproduced by the speakers. The passive crossover incorporated into the vast majority of speakers are fixed and non adjustable. Some speakers do incorporate adjustable crossovers, but again, this is beyond the scope of this post.

Active crossovers divide the frequency range before amplification, and can be adjusted to adapt to any speaker setup. They allow you to set the point at which the frequencies are divided before the audio signal is amplified and allow for certain frequencies to be directed to either individual power amps, for different drive units (bi-amping), or away from the amplifier(s) altogether. This form of crossover arrangement is generally regarded to be the cleanest and most effective. It does away with the amplification stage having to amplify frequencies that may not be acceptable by speakers that would otherwise be discarded. An active crossover also takes the strain away from the speakers onboard crossovers (if present). Basically, both the amplifier and the speakers are having to do less work.


AV Amps and Receivers (in general)

AV amplifiers and receivers incorporate their own form of active crossover filtering, allowing a user to determine where lower frequencies are sent and at which point (cut-off) the division of frequencies occurs. The cut-off point you enter within an AV amplifier's settings determines where low frequencies should be directed and at which frequency the redirection/split occurs.

Speakers you wish to apply crossover settings to must be set to 'SMALL'. This is usually done within the amplifier's speaker settings.

The size of a speaker (LARGE/SMALL) is determined by its low frequency handling abilities and not by its physical size. The full range of frequencies are sent to those speakers set to "LARGE', even if those speakers cannot handle the full frequency range (20-20,000Hz). If a speaker is set to 'LARGE' and incapable of handling the full range, the speaker's crossover will discard the frequencies the speaker cannot handle and those frequencies are lost.

In a setup who's speaker configuration lacks a subwoofer, at least one speaker or pair of speakers must be set to 'LARGE'. You get little if any say in this and the receiver will automatically designate the front left and right speakers as being 'LARGE' if a subwoofer isn't detected. Without the presence of a subwoofer, you cannot set all the speakers to 'SMALL'.

In configurations lacking a subwoofer, where at least one or more of the speakers must to be set to 'LARGE', the crossover setting of speakers set to 'SMALL' determines that frequencies below the setting be redistributed to those speakers set to 'LARGE' . This occurs even if the 'LARGE' speakers cannot handle the lower frequencies. In configurations lacking a subwoofer, you should try to use the speakers with the widest frequency range as the speakers set to 'LARGE'. Such an arrangement is more practical in configurations where the front pair are more capable than the accompanying satellite speakers. Such a configuration would be one where the front two speakers are floorstanders (full range or wider than normal) and the remaining speakers are bookshelf speakers (limited range).

In speaker configurations that incorporate an active subwoofer, connected to the dedicated LFE sub out of an amplifier, all the speakers connected to the amplifier's speaker terminals can be set to 'SMALL'. In such a configuration, the crossover settings determine at which point or points frequencies are split and sent to the speakers and subwoofer. All frequencies below the crossover setting are directed to the subwoofer and the frequencies at and above the setting are sent to the speaker or speakers the setting or settings directly relate to.

In configuration incorporating a subwoofer along with speakers set to 'LARGE', the results are much the same as those outlined above, but the full range of frequencies are still sent to those speakers set to 'LARGE', except for the dedicated LFE channel (if present). The LFE channel is output to the subwoofer via the dedicated LFE sub out. In order to send low frequencies other than those associated with the LFE channel to the subwoofer, speakers must be set to 'SMALL'.

It is generally better practice to set all speakers to 'SMALL' and use custom crossover settings when a dedicated active subwoofer is present. In cases where speakers are full range and or able to deal with frequencies at or below 80Hz then it is still suggested that a crossover no lower than 80Hz be used. You can get some of the reasoning behind this from this Audyssey article:

Small vs. Large
Do you have a subwoofer in your system? Great. Then your speakers are small. Before you get all upset, read on. This is one of those audio myths whose time has come to be busted. To understand why, we need to talk about Bass Management.

In the early days of home theater it was thought that in order to reproduce the full movie surround experience at home it was necessary to place 5 large loudspeakers in the room. The reason for the size was the woofers. To play at theatrical reference levels and reproduce the deepest bass available in the content requires each speaker to have 12” or larger woofers. Let’s just say that this theory didn’t get very far in the real world.

A better and more practical approach came after studying human perception. The mechanisms that we use to determine the direction of arrival of sound depend on the frequency. At high frequencies the wavelength of sound is small and so sound coming from the side is shadowed by our head. That creates a level difference between the sound reaching the ear closest to the source and the ear on the other side. Our brain analyzes these level differences and produces an estimate of where the sound is coming from. But at lower frequencies, the wavelength of sound gets longer and our head is not large enough to produce a level difference at the two ears. Instead, we analyze the difference in time of arrival of sound at the two ears. Sound arrives first at the closest ear and we use that to determine the direction. But even that ability fails us below about 80 Hz. The wavelengths get very large and it was found in listening tests that 80 Hz is the frequency below which most people can not localize the direction of sound.

Taking advantage of this apparent “deficiency” in our hearing was what made home theater practical for millions of homes. Five satellite speakers of reasonable size could now be used because they no longer required large woofers. A subwoofer (or two) can reproduce the lower octaves and it can be placed out of sight since its content is not directional.

But there is also a practical advantage: directing the bass to a dedicated subwoofer channel with its own amplifier greatly improves the headroom in the main channels. The idea behind this was proposed in a Society of Motion Picture Engineers (SMPTE) meeting in 1987. The participants could not agree on the minimum number of channels required for surround sound on film. Various numbers were being shouted out until a voice was heard from the back: “We need 5.1”. Everyone’s head turned around to look at Tom Holman. He proceeded to explain what he meant: Take the low frequency content from all 5 channels and redirect it away from the satellite speakers to the subwoofer. If we do the math, then the content below 80 Hz is 0.004 of the audible 20,000 Hz bandwidth. But 5.004 didn’t sound as catchy so Tom rounded up to 5.1. By the way, don’t make the amateur mistake of calling it 5 dot 1. It is a decimal: 5 point 1.
Fast forward to the early 90s when the first DSP powered home theater receivers started to appear. Along with progress came complexity. Some industry forces believed that Bass Management should be an option that could be turned on and off by the consumer. That’s not necessarily a bad idea, but to make an informed decision requires much more knowledge about the system than what was available to the typical consumer. So, the Large and Small rule of thumb was established. The idea was to look at the size of your speakers and decide whether their woofers were “large enough” to reproduce the lowest octaves at the required levels. It was a noble thought, but looking at it 15 years later I believe that it has led to nothing but massive confusion. The poor consumer was led to believe that Large is somehow a good thing and was then left wondering why there was nothing coming out of their subwoofer.

Redirecting the bass to the subwoofer relieves the receiver amplifiers from having to work on reproducing the low frequencies and this greatly improves the headroom. If you happen to be using Audyssey MultEQ for room correction, you will achieve much better low frequency performance because the MultEQ subwoofer filters have 8x higher resolution than the filters in the other channels.

Here is a better rule: All speakers are Small. In today’s complicated AVR lingo that just means: If you have a subwoofer you should always turn bass management on. Always. Even if your receiver clings to the past and automatically sets your speakers to Large.



Determining The Crossover Setting(s) to Use

Several factors need to be taken into consideration when determining the crossover setting. You need to know both the frequency range of the speakers and that of the subwoofer in order to determine the acceptable range of frequencies you can use for the settings. If you buy a speaker package then guidance on what settings to use will more than likely be outlined within the documentation that accompanied the package. In other instances then the following rules apply. The highest frequency a subwoofer is capable of handling is the highest frequency you should use for the crossover settings. The lowest frequency a speaker is able to handle is the lowest you should set its crossover to, but it is generally advised that you set ctossovers at least 10Hz higher than the lowest rated frequency handling capability of the speakers..

EXAMPLE 1
Subwoofer frequency range: 20-130Hz
Centre speaker frequency range: 70-20,000Hz

Therefore the acceptable crossover settings range for the centre speaker would be: 70-130Hz and preferably 80 - 130Hz

This means you can use a setting of 70, 80, 90 etc., up to 130Hz for the centre speaker. If you use settings above or below the acceptable range then frequencies outside of the acceptable range will be lost and not reproduced by either the subwoofer or the associated speaker.

EXAMPLE 2
Subwoofer frequency range: 35-120Hz
Rear speakers frequency range: 120-18,000Hz

Therefore the acceptable crossover setting would be: 120Hz

The above example gives no leeway for adjustment and a setting of 120Hz must be used for the rear speakers.

EXAMPLE 3
Subwoofer frequency range: 24-175Hz
Front floorstanders frequency range: 48-20,000Hz
Centre speaker frequency range: 75-20,000Hz
Rear speakers frequency range: 68-20,000Hz

Therefore the acceptable crossover setting ranges would be:
Front floorstanders frequency range: 50-170Hz (preferably 60 - 170Hz)
Centre speaker frequency range: 80-170Hz (preferably 90 - 170Hz)
Rear speakers frequency range: 70-170Hz (preferably 80 - 170Hz)

When you know what the acceptable crossover range is, there is no optimum setting that suites all situations and listening tastes. It is up to the individual to determine which setting best accommodates their listening environment and tastes. As far as the settings go, one person's nirvana may be another's hell on earth, but 80Hz is more often than not suggested as being the frequency that should be used for the crossovers if the speakers are able to handle frequency as low as this. This is because this is the point at which the human auditory system starts to localise frequencies and some individuals may be able to start detecting where the subwoofer is located if sending frequencies above 80Hz to it?


Reasons For Adjustments

There's a practical advantage to redirecting the bass to a dedicated subwoofer channel with its own amplifier. This improves the headroom in the main channels in association with the frequencies still being amplified by the AVR and being output to the passive speakers. Redirecting the bass to the subwoofer relieves the receiver's amplifiers from having to work on reproducing the low frequencies and this greatly improves the headroom.

You may ask, "why not simply use the lowest acceptable frequency a speaker can handle for that particular speaker's crossover?". In at least two of the examples above, you have a choice as to what figure you use for the crossover setting(s). If the sound is distorted, or you feel a lack of surround effects, you can redirect more bass away from a speaker or speakers in order to try clean the sound up. When dealing with dialogue and the centre speaker, you can use the crossover setting to make adjustments to the mid range frequencies associated with speech. Apart from sending low frequencies to a subwoofer that can better produce bass, the objective is to get a smooth transition of bass from the speakers to the subwoofer while also cleaning up the midrange. Note that your room's acoustics may even play a part in determining where you set crossovers. A room may effect speakers in a way that creates lulls in association with certain frequencies at different location within that room so you;d want to try portraying those frequwnciesat those locations.




I hope this brief explanation is of use to someone and thank you for reading :)

Thanks for the explanation, crossovers are so confusing my speakers have this spec

Floorstanding 39-20khz
Centre 80 - 20khz
Surrounds 90 - 20khz
Sub 40-150hz

So should the crossovers be set to
Floorstanding 60hz
Centre 100hz
Surrounds 100hz
Sub 60hz

How would I adjust to create a larger soundfield?

What Audyssey Have to Say About Bass Management


Here's what Audyssey have to say about crossover settings:

Audyssey doesn't set crossovers in any product. It finds the low frequency roll off point of your speakers and reports that to the AVR. Every manufacturer uses that information differently. In your product, speakers found to roll off below 40 Hz are set by Onkyo to Full Range (i.e. with no crossover to the sub). That means that bass will not be redirected to the sub. Audyssey recommends that if you have a sub you should set crossovers for all your speakers. I would suggest starting with 80 Hz. I wrote much more on this topic here:

http://www.audyssey.com/blog/2009/05/small-vs-large/

80 Hz is a typical recommendation. If MultEQ finds a roll off point higher than 80 Hz then don't change it. But, if any of your speakers are set to Large, then change those to 80 Hz.

Audyssey doesn't set speakers to Large or Small and most certainly doesn't set the sub to LFE+Main. These are decisions that the AVR makes. We recommend that if there is a subwoofer in the system, then all speakers should be set to Small and the sub mode should be LFE (not LFE+Main).

The LPF setting for the LFE channel should always be 120 Hz. This is not a crossover, but a filter that applies only to the separate LFE track found in 5.1 content.
Crossover frequency : Ask Audyssey


The Above is also applicable to 7.1 discrete content and not just 5.1.


The following gives some guidance on how to configure your subwoofer if relying upon the bass management capabilities of your AV receiver:

Subwoofer setup and MultEQ

Many powered subwoofers have controls that are set manually. *It's important to follow some simple guidelines to avoid having these controls interfere with proper subwoofer calibration and integration with the satellite speakers.
1. If the subwoofer provides a direct input (sometimes called LFE input) then it should always be used. *That input bypasses the filters in the subwoofer and allows the bass management system in the AV Receiver to operate properly
2. If there is no direct input, then the lowpass filter knob on the subwoofer should be permanently set to the highest frequency it allows. *That way it will not interfere with the MultEQ measurements and bass management
3. The level control on the subwoofer is often set too high. *This can cause the AV Receiver to run out of level correction range when MultEQ tries to set the subwoofer to reference level. *Set the subwoofer level control to the midpoint. *If MultEQ reports high negative trims (e.g., –12 dB) for the subwoofer, then you should turn the level control further down and run MultEQ again
4. If there is a Phase control on the sub it should be set to 0°

If you have a subwoofer with room EQ, then you should run that first in the subwoofer and then run MultEQ in the AVR


If you have an external subwoofer processor (such as the SVS AS-EQ1 or the Audyssey Sub Equalizer) you should run the calibration in that processor first and then run MultEQ in your AVR


If you have two subwoofers, there are some additional steps to take:

1. Place them at equal distances from the main listening position
2. Set the level controls on the back so they both play at the same level
3. Connect a y-cord to the sub out of the AVR and then connect to both subs
4. Turn off processing in the subs as it will not be able to give you the same resolution that you will get from MultEQ (thousands of points vs. a few parametric bands)

Thanks for this I was almost there :D
I have my sub set to full on the sub itself would I set my amp sub setting to 80hz?
The settings on the amp are in relation to the speakers. The sub itself doesn't have a setting on the amp. What is the amp and do you have the option to set the crossovers for different speakers or is the setting applied globally for all the speakers?

You also need to know both the frequency range of the sub and those of your speakers.

I have an Onkyo 605, you can set each set of speakers within a group eg: surrounds, surrounds back, centre, fronts, and LFE

Audessey sets the speakers up but puts the wrong crossover settings and the sound is a bit on the flat side as it sets the fronts to full band and limits bass to the sub

my Spec for front speakers is:
Power rating 120 Watt
Impedance (nominal) 4- 8 Ohm
Sensitivity for 2.83 V 90 dB
Frequency response 39 - 20 kHz

Driver details
LF Driver 2x5.5” Woven Composite Cone /shielded motor assembly
HF Driver 25mm soft dome
Crossover 3 Way 1st Order

For Centre
Power rating 80 Watt
Impedance (nominal) 4- 8 Ohm
Sensitivity for 2.83 V 87 dB
Frequency response 80 - 20 kHz
Driver details
LF Driver 2x3.5” Woven Composite Cone
HF Driver 19mm soft dome
Crossover 1st Order

Surrounds
Power rating 80 Watt
Impedance (nominal) 8 Ohm
Sensitivity for 2.83 V 85 dB
Frequency response 90 - 20 kHz
Driver details
LF Driver 3.5” paper cone
HF Driver 19mm soft dome
Crossover 2 Way 1st Order

Sub
Power rating 65 Watt
Sensitivity for 2.83 V 240mV for max output
Frequency response 40 - 150 Hz
Driver details
LF Driver 8” long throw
Crossover Active

Sorry for being a pest, crossovers are such a science I get baffled by it

OK, you need to set the fronts to "SMALL' or whatever the equivalent is with Onkyo receivers?

Also, I presume the LFE setting is in relation to the type of bass that is managed by the crossovers? You should set this to LFE+MAIN or whatever the equivalent is with Onkyo receivers.

When determining what is the best settings to use, increase the setting if a speaker sounds muffled and decrease the setting if the speaker starts to sound shrill or too bright. When you reach a happy medium then that is usually the setting to use.

Use the guidance I've already given in the first post to work out the acceptable settings you can use.

Excellent thanks for that, the Onkyos don't have a small setting…

I thought they had 3 settings for the speakers and bass management. 1 being all speakers small, 2 being centre and surrounds small and 3 which sets all the speakers to large?

Just been reading the 605 manual. Geez, Onkyo have one hell of a weird way of doing things. Yes, you only have control of the crossovers for the surround speakers and centre speaker. The front speakers are governed by "The low pass filter" and "Double Bass". With the low pass filter, you can specify the cutoff frequency of the LFE channel's low-pass filter (LPF). The LPF only applies to sources that use the LFE channel. The Double Bass function boosts bass output by feeding bass sounds from the front left and right channels to the subwoofer.

So will the settings you gave me earlier be precise? and what should the sub settings on the amp be set to? Double bass seems to send bass to speakers that are set to full band otherwise it is greyed out
You can use those figures for the centre and surrounds, but the LFE filter for the front speakers doesn't sound like a good option to use with the floorstanders? Try turning the double bass feature off for the fronts and see what it sounds like. It doesn't affect the crossover for the speakers it is active with, it simply boosts the subwoofers output while still outputting the lower frequencies to those speakers at the same time.

Sorry I don't want to turn this into an Onkyo 605 thread but once I'mdone I promise i'll leave you alone

So if I set the speakers to this:

Fronts: Full band with Double bass off
Centre: 80hz
Surrounds: 90hz (100hz as you can't select 90hz on the onkyo)
Sub set to full 150hz on the actual sub with volume set to full
Sub settings on onkyo to be 80hz?

Is this right?

Really sorry I seemed to have hijacked this thread

Why can't it be simple arrrgghhh!

The Double Bass function boosts bass output by feeding bass sounds from the front left and right channels to the subwoofer.

Might be worth double checking this but when I hover over this option on my TX-SR 607 it states that when Double Bass is turned 'On' Bass is distributed across both your Fronts & the Sub...

Steve athough I have fairly good quality Front Floorstands which Audessy Room EQ set as Full Band I still preferrered to switch the Full Band Off, lower the Hz (80-90hz) and keep Double Bass OFF so that only the Sub is dealing with the low bass frequencies as apose to both it and your two fronts!!

At the end of the day its primarily the Sub's job to deal with bass and should produce better sound at those low frequencies than Fronts do...


Again, as dante01 qute rightly says, it's all down to peronal preference and playing around with your system setup and speaker positioning until it feels and sounds right for your needs....

Great thread and excellent informative advice dante01... kudos..

I think that's what I already suggested and believe it is what steve69bez did?

If that's what sounds best to you, then those are the correct settings :smashin:

Tried many settings tonight and found that setting all the speakers to 100hz and LPF of LFE to 120hz seemed to give a much more ambient sound than setting to speakers to their recommended settings
Great, but I didn't actually give you any settings. I provided you with the range of settings you could use without losing frequencies altogether and you've used settings within that range ;)

The following crossover settings can be used with the AVR2809: 40, 60, 80, 90, 100, 110, 120, 150, 200 and 250Hz


Denon AVR2809 Speaker Configurations:
Set all the connected speakers as 'Small'

Set the amp's Subwoofer setting (“Advanced” settings, “Subwoofer Setup”) to LFE+Main. This will engage the sub with all channels and not just the LFE channel.


If you'd like more response from the sub, use higher crossovers on the amp. You can use different settings for the various speakers and I'd leave the front pair slightly lower than the surrounds and centre speakers.

Play about with the range 80 - 120Hz

The following crossover settings can be used with the AVR2809: 40, 60, 80, 90, 100, 110, 120, 150, 200 and 250Hz


Denon AVR2809 Speaker Configurations:
Set all the connected speakers as 'Small'

Set the amp's Subwoofer setting (“Advanced” settings, “Subwoofer Setup”) to LFE+Main. This will engage the sub with all channels and not just the LFE channel.


If you'd like more response from the sub, use higher crossovers on the amp. You can use different settings for the various speakers and I'd leave the front pair slightly lower than the surrounds and centre speakers.

Play about with the range 80 - 120Hz
