Not quite true, I did it on my yamaha during the movie section...I turned the amp gain from about 1/4 to about 3/4 before we started the movie clips because I didn't think I had the ability even to begin to push those subs into the hurt locker. (that amp gain boost on the V3000 amp was in addition to the +6dB we had bumped up the receiver for eveyone's tests). I don't think my hap hazard idea worked in my favor for the movie scenes. I'll hold my tongue from here because it's worthless to make guesswork and speculation comments. I will say this after running audessey last night on the yamaha with the amp gain knocked back down to about 2/5's, audessey calibrated the sub level to -5.5dB. I then bumped the subwoofer level up from audessey's auto calibrated -5.5 to -1 making it + 4.5 dB hotter than reference (I like a bit more bass than Audessey likes). At that point those yamaha's were pounding. This was more like the exciting sound I heard when I first hooked them up and called Luke gushing about how awesome it was to feel that level of sound in my room! I was listening to those music clips last night at +5 dB from reference on the receiver without a hint of distortion at the 2/5's amp gain. I sure couldn't do that at the meet. Granted Music vs. Movies, and I didn't watch any movies last night, but gosh darn those things were loud! During this time 2 to 2/1/2 lights lit up out of four (fifth light is the clipping light) on the V3000 amp. They don't go low but they sure do go loud. I'd be interested to let counsil and Luke and whoever, hear them again with their current calibration and see what they think. They still aren't my favorite subs, not deep enough by any means, and volume doesn't really overcome those limitations in my opinion after hearing such amazing subs as the JTR captivator and the Seaton Submersive -- which are just incredibly better, but then at $729 shipped, I don't think you could get much louder for music --- if loud and cheap and big is your thing. :P I bet they are putting up some SPL meters that would uptick from those numbers we showed in the movie scenes -- at least in the music section! I'm back to having my ears hurt after listening to these things last night, and my ears were finally feeling better yesterday afternoon from the meet's abuse.
I'll probably still return them, as I've said before - I like low, ported, and loud -- the yammies are only two of my three favorite things -- but I figured this little tidbit of info after a couple more days of owning the subs and playing with the calibration might be worth an update for anyone interested in the Yamaha setup.
Per your point. I moved two of the middle berklines and put the yamaha sub on the floor standing up where the berklines were and walked around the room. I don't have an SPL meter but I heard no particular hotspot to which would indicate a good place to put the subs to help the seating position sound best. I repositioned the subs at a different facing and tried again. No hotspots. I put the Yamaha's in the front right corner and tried all manner of directional facing. It did make bass hotspots, primarily in the opposite corner the subs were facing, but not in the right places for my seating arrangements and that placement seemed to make an audible null on either end of the seating row. I think I'm forced to have the subs underneath the screen to have the best sound spread across the four primary seating locations, but I can tell that's not the best place because three feet before the seating position and 3/4 the way back into the room both sound better than the actual seating position. My room sucks for sub placement!
