70% volume in that sized room????!! Something's screwed up. I can't get past 25% volume in a 12 X 18 room with on V4 500.

it's not so much the volume, I belive it has more to do that I feel this sub goes low enough in movies, I had a ported sub before perhaps that is the difference... or perhaps it's the ARC calibration

I would second the notion about the ARC calibration having a significant affect on the outcome. That volume setting on the sub is just too high, it doesn't make much sense. I would be curious what the calibration did to the internal sub volume within the AVR itself along with the "phase" setting. It could also be the calibration set the phase backwards which can affect both volume and the ability to hear the lowest frequencies. What volume did you have the sub itself set at just prior to calibration? Is the EP500 in the same location as your previous sub? If you can remove the calibration set-up from the picture here, see what happens to the sub volume after that.

Frankly, I have never been a fan of doing a calibration with subs since in order to provide a flat setting for the room, it tends to significantly roll off the lowest frequencies. Ian did a video on this back some time ago where he indicated any meters or calibration done below 50HZ is just not very accurate and I would tend to agree.

One valid reason why I love the Pioneer MCACC so much. It doesn't fiddle with the bottom end.

I agree as well. My prepro did some funky things with my subs too when I tried using the auto cal with subs connected.

IMO, get a calibration mic and use REW to manually cal the subs after using your auto cal software for other speakers if your AVR allows manual entries.

I don't have much faith in the built in sub eq , though I have not tried Audyssey X32. In my bedroom system I have 2 eights and I added a DSpeaker Anti mode and the difference is night and day, best 350 I spent in a long time. I measured with REW before and after and it trimmed a few peaks but it really tightened up the bass. I have a Umik-1 microphone coming and will be adding a mini dsp for my main system . As for the OP I would definitely look and see how much the ARC trimmed the bass signal going to the sub. Best to turn the sub fairly low when calibrating that way you can always make it a little hotter if you so desire.

I have had great luck with Audyssey. No funny business with the sub. Only thing it does that I undo is call my mains and center large.
