Leader
in Acoustically Transparent Home Theater Screens
"No screen we’ve
tested to date matches the acoustical transparency of the Screen
Research ClearPix2™ fabric. Now more Home Theater enthusiasts
will be able to enjoy the benefits of proper behind-the-screen
placement of the center loudspeaker, with no degradation of audio
or video performance."
-John Dahl - THX
"The
Screen Research products are now certified for Flat Spectral
Response and White Field Uniformity. Screen Research should be
complimented for supplying a screen that has not compromised
accuracy for gain. Something that is increasingly rare these days.
"
Joel Silver - ISF
Screen
Research ClearPix Screens optimal Audio and Video solution
A
proper setting for the sound when installing a Home Cinema
system is crucial for the quality of the final results one wants
to achieve.
The
ideal location of the main speaker in particular is behind the
screen, at the same height as the right and left speakers. This
guarantees:
-
Overall
coherent sound localization of the dialogues, and homogenous
sound effects.
-
Fidelity
to the original sound mixing engineered for a movie theater
where the speakers are located behind the screen.
-
Optimum
use of the main speaker avoiding negative interference from
close physical barriers (floor or ceiling). It also enables
the choice of identical speakers for the three main sound
sources since there are no longer any constraints due to
space.
-
No
more hearing fatigue due to the physiological effort the
brain has to make to compensate when locating the source of
the sound.
This
ideal scenario was up to now very hard to accomplish until now
due to the limits in performance offered by perforated and
microperforated screens generally used for this application:
-
 Significant
losses in the high pitched sounds (from –6 to –9dB),
leading to a correction in the response curve.
-
Significant
modifications of the sound signal due to the rebound effect
of the sound on the screen material leading to a ping pong
effect between the projection surface, the speakers and
other surfaces behind the screen. This phenomenon creates a
comb filter effect which perturbs the speakers’ frequency
and phase response and severely deforms the sound obtained.
This defect is impossible to correct even when using highly
sophisticated treatment methods.
-
Creation
of interference ( Moiré effect*) when using fixed matrix
projectors (DLP, LCD, D-ILA) due to the resonance between
the screen perforations and the projector pixels matrix.
