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 lively and tight.

Isothermal TubeTrap

Simply place them in the corners of your listening room or studio, and they go to work—giving you a clean musical bass line, along with added high frequency ambient sparkle.
