    hi, i have a pair of kef Q7's, an Q9c, Paragidm PW-2200 (sub) and an denon 3805 reciever. I have wondered if worth setting the front main speakers (Q7's) to large or small. I have often thought that with a sub they should be set to small, and let all low hz to the sub. However playing with some settings, and the Q7 seam to do some bass too, and what i consider large speakers (Uni-Q with 8" passive woofer).

    my question is this - is it worth setting an large speaker (such like an Q7) to large or small on the reciever (with an subwoofer)? - is there less strain on the reciever when set to small? ie. better maybe less drop in wattage of power? less chance to damage the main speakers?

    many thanks for ur time and help

    TBH there are no real hard & fast rules on the settings for speaker size. You should try different settings and stay with what sounds best to you.
    The receiver will be doing more work with the speakers set to large as the internal amps will be working with more bass. If set to small then all bass would be sent to the sub with its own internal amp, this leave the receiver more headroom to work with the midrange & treble. Either way should not cause any damage to either the speakers or the receiver.

    i let the 3805 set up my speakers with the auto calibration, i use mk k17s at the front although they are quite small, on auto they were set to large by the 3805, tried them on my previous amp the 3802 on both small and large and prefered the setting at large, all down to personal choice

    Large and Small seem to be a bit misleading as descriptions for the settings!

    Denon explained it in simple terms to me as follows;

    Use the Large setting if your speakers are also sold as 2 channel HiFi speakers (Because that will mean they were designed to reproduce a full frequency range).

    Use the Small setting if your speakers are only available as a sub/sat package (Because this means they were designed to share the frequency range between speaker and sub).

    The reasoning is that in the Small setting, the lower frequencies (not just normal sub-woofer low!) are cut from the normal Left/Right etc.. outputs and are added to the LFE channel.

    So, using KEF as an example -

    Use Large for the Q series, XQ series and Reference series.

    Use Small for 1005 and 2005 series


    I have Q1 for L,R,SR,SL; Q9C centre and a 2005.2 egg for Surround back and have all the Q1's set to Large and the egg which is small (there was even a note in the box stating that this is how the egg should be set).

    At the end of the day though, set it how you like it - 'cos it's your enjoyment that matters!

    :eek:

    I'm pretty sure (really really sure!) that you should set the K17s to SMALL with a crossover set to 80Hz at which point your SUB will take over.

    What sub do you have?

    ah i see, so speakers which are only avaible in a kit (with subwoofer) should be set to small, otherwise up to the user.

    when they set to large, is there any benefits from it (with subwoofer)? and what would this do exculty in movies and music (with subwoofer)?

    with the k17's they do look like a sat thing to me (read somewhere 80hz response), however theses speakers like Q7 etc. u are looking around 35hz repsonse

    many thanks

    Very few speakers (very large and expensive), are really full-range, so all home friendly speakers should be set as small, even floorstanders, as a bonus it saves some power from the receiver, as someone already mentioned... :lesson:

    Of course if you amp does poor bass management or your sub is not up to the task, you may get better sound with the speakers as large... :rolleyes:

    also i am sure it said in the 3805 set up it does detect the freqency range of each speaker so if k17s are not full frequency why did it set them at latge

    seems like the auto-setup is falsely detecting the M&Ks - check the spec on them and you'll see they reproduce anything from 80Hz up, also I'm pretty sure that somewhere on the manual it'll say to set them to SMALL !!

    Did you actually try setting them all to small & crossover at 80hz (maybe 100hz) using the 3805?

    Oh! wait a sec! how's your sub connected to the amp!???

    nah - ok false alarm, was thinking it was connected via high-level (and that would mean SPKRS set to LARGE)

    so as we where saying before - I would set them all to small (fronts & rears) cross them at the 80 to 100 range and have a go at listening to them! you should get much better sound in music (stereo), and movies i'd say too!

    but at the end set it to what sounds good to you!

    80hz might be too high with just one subwoofer, particularly if the xover has a slope less than 24db, I would use 60hz for those speakers...

    My front speakers go down to 35hz and I use the xover at 80hz, before I used 60hz, but as I have two subs it works fine at 80hz, can´t "hear" the subs...
