You can bet it's not doing it any good!

I agree it's not a good thing. I believe it would be worse if it were a
DLP with the colorwwheel.

I would suspect that if it were a problem, convergence would be an issue.

My CRT RP virtually NEVER needs convergence.

Thanks It is the protective screen.

Most rear projection TVs have a protective screen over the front of the
actual projection screen. It might just be the protective screen flexing.
If you put your hand on the TV, can you feel it vibrating?

50+ Inch rear-pros ontop of SUBWOOFERS?!?????? ?

Because right about now I have a crystal vision of the television
sitting atop a 4x4x4 foot bass bin usually found in a nightclub. And
if that's not the case, then what level is this sub set at so as to
rattle either the screen or its protective surface? Because I'm
getting another vision of one of those "ricer Honda Civics with about
2,000 watts divided into 4 12" kickers in the back seat" deals where
the license plate, back window, and just about eveyrthing else in back
is about to fall off the car from the vibration.

Have all your speakers(sub included) been calibrated with a dB meter?

The suspense is killing me...

One of mine is located about a foot away from the TV. I play my system at
moderate volume and both subs will go down to 20hz.

15" subwoofer @ 500 watts, 5 feet from screen
calibrated/balanced with the THX setup disc.

Don't have a dB meter, but I can assure you that this system definitely
shakes your gut in scenes with deep bass... earthquake movies are moving the
house

My sub is a coffee table sized object (19"Hx72"Wx24"D) with two
acoustically suspended, magnetically shielded 15" woofers, each in it's
own chamber. The power is provided by a 400W amp driven by a tuned
equalizer. It is flat down to 20Hz and has significant output down to
15Hz. It rolls off at 6dB/octave above 120Hz.

Have all your speakers(sub included) been calibrated with a dB meter?

Yes. I have it peak limited at 110dB. I don't need no steenkin' seat
shakers.

The suspense is killing me...

I hope this is in time to rescue you.

110dB. I don't know what the recommendations are(from folks like
Dolby), but that sounds a *little* high.

I treat LFE like surround - it should be come conspicuous only when it
is missing or turned off. Constant surround - or in a subwoofer case -
constant thunder, where you can here it even in male dialogue, would
fatigue me right out of the room.


IFYPFY?? Huh?

Normally yes, but when there is a serious infrasound event in a movie, like
an explosion, the extra whumpf is nice
