hijacked the audio fidelity you bought.
Reclaim the performance you paid for; Tighter Bass, Warm Vocals,
Increased Decibel Level.
The SandTrap is a patented measurable, demonstrable solution
for custom architectural in-wall/ceiling speaker systems.
Speakers mounted in drywall (paper, chalk, and glue) generate muddy
bass, harsh mid-range vocals, and forfeit decibel level -- distortion
caused by the inherent unwanted resonance of drywall. Drywall
destroys the heart of music and movie soundtracks.
To The Rescue
The SandTrap architectural speaker tuning system crushes drywall
distortion. The SandTrap reclaims the audio performance
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.
