Why would you want to damp the back wall? Certainly the wall behind 
the cabinets should be as dead as possible, but damping the back wall
would kill the reflection (except for the low end). I would put 
diffusion on the back wall, kill the reflection behind the speakers,
damp the sides to about half way back and possibly put corner loaded 
damping in the back corners. This way, you would end up with something 
similar to the acoustics of a control room, which is where most 
recordings are made and mastered. You would hear the repro the way the 
engineer heard it, which is ideal.
 
 GG> The Definitive Sub is worse yet at around 100 lbs.
 GG> Fortunately, I didn't have to move it around much.
 
A single sub that weighs 100 Lbs? That's pretty light. Each of my home 
subs weighs over 185 Lbs.
 GG> I'm pretty much set on moving my TFM-35x over to surround duty

1200 watts into 2 ohms? The damping factor would suffer at 2 ohms. 
I never load my amps at home lower than 8 ohms, because the damping
factor falls off sharply below 8 ohms, although the amps are rated 
for 2 ohm loads.
 
 GG> I'd like to replace my cd player with a Sony XA3ES too, it being

If you want state of the art, stay clear of CDs. 16 bit wordlength
and low sampling frequencies just don't cut it for anything above 
about 4Khz.
 GG> Well, Carver amps are voiced and TFM modified to sound like
 GG> Bob's Silver Seven tubes.  While I haven't heard *those*, I don't
 GG> doubt the TFM series sound a little different than a
 GG> solid-state-as-you-can-get Bryston.  
 
This is true; nothing that Carver makes can come close to the sound 
of the Brystons. The only thing that beats a Bryston is an FM Acoustics,
but who can afford those beauties?
 GG> The Sonic Holography is incredible. 
That technique has been around for decades; modern techniques are far
more convincing.
 GG> I have a tube guitar amp.  Frankly, I hate it.  The
 GG> replacement tube I bought sounds like crap and the original lasted
 GG> barely a year.  
 
You might try Whirlwind's new line of tubes. I have had good luck with 
them every time I have replaced tubes for someone, and they are so well
matched that once you install a set you won't even have to rebias when
you replace them with the same tubes!
  
 GG> Ironic that Sony also sells dirt cheap crap. :)
That has been my experience with all Sony consumer products. Even my 
Sony TV died on me 3 years in a row, until I put a reliable voltage 
regulator in it. The professional Sony gear is good though. :)
Take care.
... ..But if you overload it...POOF, all the smoke leaks out!
