Elite Screen: Passing Audio High Frequencies
Although I do not have speakers mounted behind the screen, there was sufficient space behind the screen to put a small
iPod speaker system with good high and mid-frequency sound. In listening to the speakers, first, behind the projector
screen surface, and then in front of it, I was able to determine that there is a definite, but not great loss of high frequen-
cies. Instruments like cymbols loose their crispness.
If you are big on music listening, in addition to movies, as I am (I spend a lot of time watching/listening to music DVDs),
then understand that you are giving up something by going to this acoustic surface. Unfortunately I don't have a good
reference as to whether this Elite Screens' surface is better or worse than most other acoustic surface, in terms of loss of
frequency. If, on the other hand, you are into primarily video, and the movie effects types of sound (think action film), then
you probably won't care about a slight loss in the highs.
Elite Screen: Overall Sound Levels
Sadly I don't own an SPL meter (sound pressure level), so I couldn't measure the volume difference between the sound
system being behind, or in front of the screen. I spent many years in the high end audio business, though, so I can make
an educated guess. Overall, I'd put the sound loss as very low, almost certainly less than 3db, and probably around 2db,
or a small bit less.
Since, again, I don't possess a good pair of in walls speakers in the testing room, I also could not determine whether a
speaker system with fairly large mid-range or woofer, will vibrate the surface of the screen enough to see it react, at high
volume levels. (Think of the speaker cloth on your big old speakers moving/vibrating when loud passages with bass and
lower mid-range content are played. The surface itself seems fairly rigid, compared to the typically thinner material used
on non-acoustic projector screen surfaces.
Elite Screens: Light Interference and Reflections
Whoa! Remember, that when I am viewing this screen, it comes down directly in front of the Carada's surface.
And, boy, is that a problem. Light passes through the screen, bounces off the back screen, and passes back through the
Elite screen. This makes for a major disaster. With a white surface behind this Elite screen, all kinds of terrible things
happen. First, you get a sort of moire' pattern kind of effect from the slightest movement of your head. But even more
important, you can see the edges reflected image all around the edge of the screen.
To some degree or another this is a reality with acoustic materials, though some companies no doubt do a better job than
others.
The solution is simple. The wall behind the screen needs to be dark, very dark, ideally black, and assuming paint, flat paint
- none reflective.
It is absolutely essential that whatever surface is behind your screen, is both dark and non-refective.
If you just happen to have in-wall speakers with a white grill, get black grills. If the surface of the screen grill is a black
finish, but highly effective, do something - repaint them with flat paint. You don't want anything reflecting back through the
screen. Believe me!
I was able to place a large sheet of dull black surface behind the Elite screen, and the problems went away, nicely.
