Got the four SVS SB16-Ultra subs in and placed two of them up front like I normally do my pairs of subs... and after removing one of the four recliners on the back row of the room, and centering those up, I placed the other two on each side of that row on the ends. I figured that would be a good starting point and my preferred location. I was going to start by measuring each sub with REW to see what they looked like individually, then do them in pairs up front, then pairs in the back, but then decided to just try them all at once and see what it looked like first. After tweaking the phase on the rear subs that are a little closer to the main listening position... this is what I got (red) and with 1 PEQ filter in the front subs, and 1 PEQ filter in the rear subs, I was able to smooth it out (green). Ready for Dirac Live.
Before I show you the Dirac Live corrected response... look at what the fronts looked like vs what the rears looked like... both in pairs...
Those are fairly rough looking response individually. I got seriously lucky on the placement of these with such a beautiful looking combined response. It would have taken quite a few filters to straighten out that mess. It's just not everyday you can plop down 4 subs in a room and it come out that good.
Then I decided to see how far I could push them before REW hit the red... this was with the sweep just barely hitting the red a 4.8. Flat to 15Hz at 105dB... compliments of some nice room gain.
Then I ran Dirac and brushed it on up a bit...
Waterfall... not bad at 95dB ... considering there isn't much to be done about that area down low.
