Speaker Tuning System
Custom audio/video dealers who offer and install premium in-wall/ceiling speaker systems.
Custom speakers mounted in sheet-rock generate muddy mid-bass, harsh mid-range, and
forfeit decibel level. The source of this distortion lies in the inherent out-of-phase resonance
Unwanted resonance is the issue. Managing resonance is the solution.
Re-tune sheet-rock mounted speaker systems with a mechanism that minimizes unwanted
resonance -- creating tighter bass, warmer vocals, and revived decibel level.
hollow framed birch wood backed speaker baffle. The sand filling provides more net mass
than the staple of speaker cabinet construction --- medium density fiberboard. Sand increases
frame weight from approximately an empty 1.25 lbs to a sand-filled 5 lbs. We employ the
increased mass to re-tune and minimize oscillating sheet-rock resonance.
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 of only $69.99.
The Distortion Gap
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 out-of-phase sheet-rock resonance. Sheet-rock destroys the heart
of music and movie sound tracks.
Bridging the Gap
The following graph clearly illustrates the sand-tuned result of the SandTrap reviving the
previously cited sheet-rock mounted Paradigm custom speaker. It positively -- measurably
and demonstrably -- reversed the distorting effects of sheet-rock.
The SandTrap is a low cost, profitable (Up to 64% GP), measurable demonstrably solution and
sales tool to close big ticket project sales.
