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.
