Patented Architectural Speaker Tuning System
Reclaim The Performance You Paid For
Tighter bass, warmer vocals, increased decibel level

for custom architectural in-wall/ceiling speaker systems.
Speakers mounted in paper, chalk, and glue -- Sheetrock -- generate
muddy bass, harsh mid-range vocals, and forfeit decibel level --
distortion caused by the inherent unwanted resonance of
Sheetrock. Sheetrock -- destroys the heart of music and movie

reverses sheetrock distortion. The SandTrap system reclaims the
you paid for --- tighter bass, warmer vocals, restored volume level.
The easy to install SandTrap accommodates prevailing premium brands
of custom-installed in-ceiling and in-wall speaker systems.
