When this happened with my mrx300 it was a reinstall of the software for me?

Don't know if that helps, and avs might be a better place to look ,more Paradigm owners there.

Hows it sound? Worth £99????
I'm still playing about with it at the moment but the bass frequencies arnt as dominant as they were it seems more controlled and tight. I thought the sub wasn't switched on at first lol do you know how to activate the live mode on the pbk? I want to find the best position for the sub before I run the pbk :)

I dont have a pbk only mrx300, the arc software has an option called quick measure? You open that and have to wait for around 10 sweeps then you start seeing it "live" and move whatever speaker around to see what it does.

Yes found it mate but for a novice like me I don't know what my ideal position should look like, the graph changes when I move the sub but I don't know what I'm looking for lol :)

Fowl3r - I'm also a novice but think I can gve you some advice..
Like Tom I also do not have PDK and have an Amthem MRX300 with ARC…
I've only started to play around with this over christmas

Check the US forum - search for ‘Anthem MRX Receivers'
- The thread is huge, I've followed it from start to finish and got used to checking forum members subwoofer graphs.
(I bought the Anthem to remove the boomy bass I used to have...)
- Go to post # 2, at the bottom is an image of what your target is….
- apparently the idea is to “look for a red measured line that tracks flat from 100Hz to 20Hz and below”

My Red (measured) line is all over the place ( up..down…up...) but I got the Green (Calculated) line to match 95% to the BLUE (Target) graph. I've watched a few movies in last few days after this and bass is tight and I'm liking it a lot.

Looking at the graphs on Paradigm PBK-1 Subwoofer Edinburgh, Aberdeen, Glasgow, Scotland, Newcastle, UK
- PDK graph seems to use different colours but the principle is the same.

Check the below link I'd saved ages ago - It gives useful step by step overview along with laptop screenshots.. Paradigm PBK-1 Perfect Bass Kit - Box Contents

My subwoofer is located under my screen in a home made screen wall, ideally I'd like to leave it where it is for aesthetics etc but I'm going to have a play this weekend to see if I can get the Red (measured) line to display as flat a line as possible and if I can then I might leave the sub there for a while to see what it sounds like.
Rather than moving the sub around multiple times I'm going to try the below tip that I saved from that US thread which you might find useful:

1) Place your sub in your listening position (literally)
2) Take your ARC mic, in Quick Measure Mode and walk around the room sampling areas where you could put the sub.
3) Once you find the best looking graph with Quick Measure, swap the Sub and the Mic positions. Believe it or not, they should look almost the same!


- I'm 80% certain I read you can do this exact same using PDK. Hope this is helpful.

1) Place your sub in your listening position (literally)
I'm afraid that is a common misconception about subwoofers. Placing the subwoofer in the listening position and then measuring the response at various other positions will not tell you what the subwoofer would sound like at those positions from the listening seat. The effect that a particular location would have on the subwoofer that is the source of the audio will not have same effect of the microphone which is listening to it. Likewise with the subwoofer in the seating position it will not be as directly affected by the boundaries that would have been next to it if had been placed in a corner. You need to do all measurements with the microphone in the listening position and the subwoofer on the actual location you intend to use it in.

Basically the the Quick Measure function is intended to firstly make it easy to identify the best sounding location in the room for the subwoofer if there are several options available and you can then fine tune the exact position of the subwoofer to give the best response before running the PBK.

When using the Quick Measure function, all you are looking for is the solid red 'Measured' line which is closest to the dotted blue 'Target' line. The closer the uncalibrated 'Measured' line is to the 'Target' line before running the PBK the easier it will be for the PBK to achieve a result that matches the the 'Target' line it is trying to achieve. The purple 'Calculated' line after running the PBK shows the response of the subwoofer with the PBK calibration applied.

I hope that helps.

Cheers,

Chris.

Cor blimey they are awful! The pix not the charts!
Do you use a windows7 machine? I found the snipping tool excellent for posting charts, it basically takes a picture of the page!

Have a look in my taming a dip thread you will see what it can do!

As for the charts, they look ok what does it sound like?

Have to agree, they are almost illegible. If you have windows Vista or Windows 7 use the snipping tool.

Or do an 'Alt+'Print Screen' and then crop the image to show the graph only.

Here are some examples of recent PBK results I've had on a few installs, I have zoomed in on the 0-100Hz range as that is where it really matters most anyway:

Interesting charts! Thanks for posting them Chris.
