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.

In-ceiling SandTrap

Easy Install  

Insert the four sand-filled hulls through the custom speaker cut-out
and hold in place with an adhesive.  Insert the custom speaker
and clamp it 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 1.2 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 10 decibel loss
from 600Hz to 1.5KHz, of a Paradigm P65-R in-ceiling speaker
mounted in a 2" x 4" 16" O.C. wood stud
drywall faced infinite baffle enclosure. 
Drywall destroys the heart of music and movie soundtracks.

   Before Custom Installed Speaker Tuning System

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.
