Have you ever solved a high end audio issue using non-audio technology? Or, visa versa?


Sometimes we just have to be creative to fix a problem.  Our "bag of tricks" may go well beyond the usual "audiophile grade" tools of the trade to produce a positive result.

Here's one:

Years ago, I acquired a little British sports car.  This, itself is an unusual story.  I'm a performance car enthusiast with a 835HP vehicle is parked in my garage.  

At any rate, the little 4-cylinder "tractor motor" had solid lifters that sounded like a Singer sewing machinegoing down the road above 3,000 RPM.  It distracted from the driving experience.  I was thinking how nice it would be to quiet them down a little.

Then I remembered the can of Acoustical Magic material I had in the basement.  For those unfamilar with this material, it's used to dampen the vibration/resonance of turntable platters.  I pulled the aluminum valve cover, cleaned and degreased it thoroughly, then applied a generous portion of Acoustical Magic.  After a little curing in the oven and allowing it to set for 24 hours, the valve cover was reattached.

If I had it do over again, I would have measured before/after with a spectrum analyzer. But, my best guesstimate is that there was a 6-9db drop in the tapping sound, and I could hear the sounds around me while cruising.  The driving experience improved exponentially.  Thanks to Acoustical Magic for a cheap, effective solution to my "acoustical" problem.

I have to admit that a year later the true "hot rodder" in me required that I add a turbo to the little engine.  The sound of the off-throttle blow off valve is music to my ears.  And, driving something resembling a real sports car, as opposed to a British commuter car was a plus.

I bought some heavy duty equipment vibration control pads for under the 4 rectangular feet on my Volti Rivals (135lbs.) They are made of a dense closed cell foam sandwiched between two pieces of rubber. I have a large room with long floor joists that I suspected were causing a lack of overall definition in the lower mid/ upper bass area. $32 later for 8 & voilà! Great improvement! They are available in many sizes from 2”x 2” on up & they’re about 3/4” thick. 

Tissue to tame excessively spitty tweeters. First recognized as a "Yamaha NSM 10" mod.

The Tiger could also be called a Ford. I'm considering converting my BGT into Sebring clone with Ford or Rover V8, then I'd have fast car that felt scary fast!

@sns That little "Buick" V8 is pretty special.  Should pull nicely and make "good noises".
