Now you can paste that into, say Windows Paint (bundled with Windows) and Save As the result, choosing the JPEG file format to keep the file size small.

You can't view all the charts at once, so you capture the upper charts, scroll down and then capture the lower charts. If you have a separate Music configuration you do this again for those (select Music in ARC's View menu to see those charts). Then bring up your Targets window and capture that as well. The end of all this is 5 JPEG files on your PC which you can then upload to AVS as part of a post here using the Manage Attachements feature found below the box where you type in your post text. Use the Preview Post button to convince yourself it has all worked before you Submit Reply.

The first thing to look at is your Sub. Its red Measured curve suggests it has an internal crossover still active inside it, probably around 80Hz. You want to turn that off or bypass it. If you can't bypass it, set it to the highest possible frequency to get it out of the way as much as possible, as right now it is artificially reducing the high frequency end of bass output from your sub. Your MRX will take care of crossover processing so you don't need the sub to do it as well.

NOTE: If you set a THX setting in your sub, it may force an 80Hz crossover that you can not adjust. So don't do that.

Next the low frequency end of your sub is showing as good down to about 30Hz. This is the point where it drops below the basic volume level of the solution. This is not bad, and is rather typical of home theater subs, but you should be aware that there are subs out there which will go at least an octave deeper -- down to 15Hz -- the so-called subsonic bass that you more feel than hear. If you were expecting YOUR sub to be able to do that, check to make sure you don't have a subsonic filter turned on in it. Sometimes this masquerades as a setting for when the sub is "too close" to a wall. Fib and say your sub is not too close.

Center and LF both show a Measured peak at 40Hz that ARC is having trouble fully correcting, basically because of the dip immediately adjacent. If your sub had better high end response one solution to this might be to raise the cutoff/crossover a bit for LF/RF and for Center in the Targets window and depend upon the sub handling those frequencies. Another solution would be to experiment with some positioning adjustment for LF and for Center that helps minimize that Measured wobble near 40Hz. The Quick Measure feature (ARC Tools menu) will allow you to see how the Measured curve changes in real time as you shift the speaker. At these -frequencies, even inches can make a difference.

What you have right now should sound quite good, but with a few tweaks like this it can get better.

Would I go about these changes you mentioned by entering the manual set up screen and making the changes from there?

From what I read on your sub it has an internal crossover override control. make sure you have that set and remeasure and post your results. Don't forget the targets page. From there Bob can make suggestions for improvement using the ARC application.

Based on the HSU web site, your subwoofer has a crossover override switch (crossover in/out) - just flip it to 'Out' and re-run ARC. This will override the crossover and your subwoofer signal will go straght to the subwoofer amp - essentially the only HF cutoff that you will have will come from the natural limitations of the woofer cone itself. This should give ARC more room to work with.

Thanks for the quick response.
So when I set it to out, do I make any changes to the crossover volume knob or just leave it as it is? When I rerun ARC can I just re run the sub or do I have to do all speakers again?

I don't know ARC well enough but it should be enough to rerun sub only
(ARC experts, please correct me if wrong).

However if you do sub only, all settings for ARC will be gone so after any quick measure you have to do a new full measurement or upload a previous ARC file. Since a change to how the sub will be measured has been made, a Full ARC measurement should be done so ARC can make changes to all the parameters that are affected by the sub output.
