SHOW DEMO! TubeTrap Isothermal, 16x3' by Acoustic Sciences

Blue Spruce
Silver Papier
Medium Grey


Take advantage of this opportunity to outfit your high performance audio room with nearly-new TubeTraps that were used at the Pacific Audio Fest 2023.  These units absorbed sound for only one weekend, so they have plenty of remaining capacity. Just kidding---TubeTraps NEVER run out of sound absorbing power!

If you love a bold blue or an aqua-green, today is your lucky day! The only remaining stock includes 2 handsome custom colors - at no upcharge! (updated 9/6/2023). 

Meet the big brother of our workhorse 13" TubeTrap: the 16" powerhouse!  With deeper bass extension and greater overall absorption, the 16" Isothermal TubeTrap can either be added to an existing system or used as a foundation.

Bass Trap with Built-In Diffusion

Audiophiles & Recording Engineers have relied on the Award winning TubeTraps to get their room sound just right.  The IsoThermal TubeTrap continues this tradition with our new patented technology by delivering twice the bass absorption power, a fully adjustable diffuser with dynamic broadband sound absorption and diffusion.  As the acoustic powerhouse for solving your room's sonic problems, the Isothermal TubeTrap offers extended bass absorption and treble range diffusion to help your room sound tight while maintaining a naturally lively ambience.
