The SandTrap
The SandTrap is a sand-filled ABS plastic-framed birchwood-backed speaker sub-baffle.  Each baffle is quartered and shipped as empty hollow hulls.  Each hull is sand-filled with sand provided by the installer.  The ship-empty sand-filled on-site feature significantly reduces shipping cost, which permits the SandTrap's low price.

Easy Install
The four sand-filled hulls insert through the custom speaker cut-out and are held in place with an adhesive.  The custom speaker is then inserted and clamped to the inner-rim of the SandTrap sub-baffle.

More Mass/Weight Than MDF
Sand provides more mass & weight than the staple of speaker cabinet construction -- medium density fiberboard.  Sand increases empty SandTrap weight from about 1.25 lbs to a sand-filled 8 lbs.  We employ the increased mass & weight to re-tune speaker system resonance, minimize (paper/glue/chalk) drywall distortion, maximize audio fidelity.

The Measured Specs 

This graph 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 2" x 4" 16" O.C. (paper/chalk/glue) drywall enclosure.  Drywall paper, chalk, & glue destroys the heart of music and movie soundtracks.

  

The following graph illustrates the result of the SandTrap reviving the previously cited Paradigm in-ceiling speaker.

The SandTrap -- measurably & demonstrably -- reversed the distorting effects of (paper/chalk/glue) drywall.

 

Two SandTrap Versions
The SandTrap is available in an in-ceiling & in-wall version.
