Meet the 13×3 Isothermal TubeTrap

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 workhorse 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 TubeTraps are ​modular​, ​self-contained​, ​broadband acoustic absorber/diffusers​ that improve the quality of music playback. No tricky installation required. 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.
