Product SpecificationsThe SandTrap is a sand-filled ABS plastic framed birch wood backed
speaker baffle. 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-fill on-site' feature
significantly reduces shipping cost which permits high dealer profit at
an easy to sell retail price.
The SandTrap is installed through the custom speaker cut-out and held
in place by an adhesive. The speaker is subsequently installed through
the cut-out and clamped to the re-tuned SandTrap surface.
More Mass than MDF
Sand provides more net mass than the staple of speaker cabinet
construction -- medium density fiberboard. Sand increases the
SandTrap weight from about an empty 1.25 lbs to a sand-filled 5 lbs.
We employ the increased mass to re-tune speaker system resonance,
minimize sheet-rock distortion, maximize audio fidelity.
This graph exposes a vast distorting gap with an average 10 db loss
from 600 Hz to 1.5 kHz of a Paradigm P65-R in-ceiling speaker
mounted in an infinite baffle sheet-rock enclosure. The gap is the result
of distorting out-of-phase sheet-rock resonance. Sheet-rock simply
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. It positively -- measurably
and demonstrably -- reversed the distorting effects of sheet-rock.
