I re-calibrated it again today no different that before. Pioneer's MCACC with mic on tripod in center of room at sitting ear level. Even so, the VP150 still seems to be the loudest component. I may turn it down a decibel later. MCACC set the L and R at -2.5 and the Center at -1.5, sub at +0.5. It would be nice if it were possible to turn the VP150 down separately than the M2, but most volume controls aren't made for over 100 watts, so I'm not sure how I can change it yet. The 150 plays a couple of Db higher than the 100, and the M2 a couple of db lower still.

While listening to Dave Matthews and Tim Rynolds blu-ray, I set L/C/R all to -2.5 and it sounds much more even.

It seems pretty obvious to me that you can squeeze two more speakers on either side of the M2....

I've also got about 3 foot of space above the speakers for 2 more rows, but nah. Someone else that's seen it has suggested I start on the ceiling.

I bought a new blu-ray player today. My first with wifi. I hope it streams Netflix ok. It's a Panasonic DMP-BDT210P.

I noticed last night when listening to some music, that the off-axis sound from the VP150 was different than the off-axis sound from the VP100. I can't put my finger on the quality of the change yet, but I thought I'd point out that there was a change, and not necessarily in a good way, but not all that bad either.

The problem with the downward center sound you are encountering is that the VP150 is 6 ohm speaker and the M2 is 8ohm, unless you have one of those speakers on it's own amp with a volume adjustment, the VP150 will always be playing louder by about 1-2 db.

It was just something I noticed when I was listening to some music in my recliner, off-axis. It seemed to be more of a design quirk with the VP150, is the best way I can describe it. Changed the sound is some subtle way.

I made a slight change on my EQ settings in my AVR a couple of days ago, and I'm amazed at how such a slight change can greatly affect the sound.

All I did was decrease 1/2 db from 1000 hz to 20,000 hz. on each of the available sliders. Most of my high end problems went away where it seemed a bit too bright, and the bass is more noticeable now.

An in-line attenuator might help in a situation like that, like the ones at Parts Express(as little as 1db up to 12db, iirc).

They have this one that might work. It only comes in a rack mount version. My only requirements are it has to handle at least 100 watts and not be a 3db per increment attenuation switch. This is the only one that meets those requirements.
