The SandTrap Story
Custom Installed Speaker Tuning System

          It's a sunny January California morning.  I'm living a comfortable 
retired life --
 coffee with my daughter and three sons at a favorite haunt. 
We're engaged in
the great American pastime of concocting new product
ideas.  Some ha
ve a thread of credibility.  Then I offered, "isolating baffles 
for custom speakers."  That
comment produced glazed looks that asked, 
"What is a baffle
and why would anybody want one?

          Consumers spend premium dollars for speakers that can't be seen.
Well ---
they’re less visible.  The audio industry promotes these speakers
as custom installed speaker systems.  
The good versions are not cheap. 
They range from $
600 to well over a $1000 per pair – plus installation.
The issue is they are installed in sheet-rock walls and ceilings.  Sheet-rock 
is made of
paper, glue, and chalk.  This is not a good material for
reproducing sound
from any speaker.

          Mounting a speaker in sheet-rock is much as selecting a set of 
guitar strings for their potential increased volume and greater sustain;
then stringing the set on an acoustic guitar made of corrugated cardboard.
This is not a good idea.
 Similarly, sheet-rock compromises the sound
custom installed speaker systems.  Sheet-rock mounted speakers
generate muddy mid-bass, harsh vocals, and forfeit decibel level.

         “OK Dad", they asked, "What are you proposing?"  I propose to add  
an isolating
mounting surface behind the sheet-rock and speaker; a surface 
minimizes sheet-rock induced distortion by re-tuning the speaker 
system resonan
ce.  This will result in tighter mid-bass, warmer vocals, 
and higher decibel level. 
This is particularly well suited for the $500 to 
$800 per pair speaker
category.  This isolating baffle will squeeze enough 
improved performance to compete with much more expensive

          To my surprise they were still listening.  So I continued.  I would
offer this solutio
n to custom AV dealers at a dealer price that would
make it impracticable for
the dealers to build baffles themselves.  It will be
easy to install; and I would offer the baflfles at
a retail price that makes 
consumers and dealers
smile.  I then outlined how it could be accomplished.

          They looked at me and said, "
Dad, it's a no brainer --- do it."  
That's how I exited retirement and became the 
captain of SandTrapAudio.
