The SandTrap Story
 Custom Installed In-wall/ceiling
 Speaker Tuning System

It's a sunny January California morning.  I'm living a comfortable
retired life; drinking
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 have a thread of credibility.
Then I offered, "
Isolating baffles for custom speakers." That comment
produced baffled looks that asked, "W
hy 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 $1000 per pair
--- plus installation.  

The issue -- custom speakers are installed in sheetrock 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 sheetrock 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 cardboard.  This is
not recommended. Similarly, sheetrock compromises the sound
of custom installed speaker systems.  Sheetrock 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 sheetrock & speaker; a surface
that minimizes sheetrock induced distortion by re-tuning the speaker
system resonance.  The result is tighter mid-bass, warmer vocals,
and higher decibel level.  This is particularly well suited for the $600
to $800 per pair speaker category.  My isolating baffle will squeeze
enough improved performance to compete with much more expensive
custom models.  

To my surprise they were still listening.  So I continued.  I would offer
this solution to custom audio/video dealers at a dealer price that
would make it impracticable for the dealers to build baffles themselves.  
They will be easy to install; and I would offer the baffles 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 SandTrap Audio.
