So there's been this add popping up locally for an "Audio" company wherein the fellow claims to be able to instantly increase the bass response and SPL of ANY musical instrument speaker enclosure. Using a "specialized polymer compound" he sprays this stuff directly onto the speaker cones and "adds suspended mass" to the drivers and instantly creates a "deeper and more musical response" from your tired old vintage 30's or Eminence woofers. This sounds like hooey to me, and adding mass to speaker cones seems like it will definitely change the T/S parameters... but in a dangerous and unhealthy way... not a "more musical" way..... Anyone? I'm told the secret sauce "smells like hairspray"
