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 low
dealer cost at a profitable easy to sell retail price.
Easy Install
The four sand-filled hulls are inserted through the custom
speaker cut-out and 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 1.25lbs to a sand-filled
8lbs. We employ the increased mass & weight to re-tune
speaker system resonance, minimize sheetrock 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 sheetrock enclosure. Sheetrock 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 sheetrock.
Two SandTrap Versions
The SandTrap is available in an in-ceiling & in-wall
version. Select their links to view product and installation
