According to Sand trap audio says that custom speakers mounted in sheet-rock generate muddy mid-bass, harsh mid-range, and forfeit decibel level. It claims to have a solution that manages resonance, as unwanted resonance is the issue. The solution is to sandbag the speakers with ABS plastic, birch backed and sandfilled baffles. These re-tune sheet-rock mounted speaker systems.
The SandTrap, demonstrated at Cedia 2019 in Denver next month, re-tunes sheet-rock speaker resonance via a sand-filled ABS plastic hollow framed birch wood backed speaker baffle. The sand filling provides more net mass than the staple of speaker cabinet construction --- medium density fiberboard. Sand increases frame weight from approximately an empty 1.25 lbs to a sand-filled 5 lbs. We employ the increased mass to re-tune and minimize oscillating sheet-rock resonance.
Each baffle is quartered and shipped as empty hollow components. Each is sand filled on-site by the installer with sand provided by the dealer. This "ship empty" "sand-filled-onsite" feature significantly reduces shipping cost which permits high dealer profit (up to 65% gross profit) an easy to sell retail price of only $69.99.
The Distorting Gap exposes a vast distorting gap with an average 10db loss from 600Hz to 1.5KHz of a Paradigm P65-R in-ceiling speaker mounted in an infinite baffle enclosure. The gap is the result of out-of-phase sheet-rock resonance. Sheet-rock destroys the heart of music and movie soundtracks.
