The One. The Only. The TubeTrap.

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.

Audiophiles & Recording Engineers have relied on the Award winning TubeTrap for decades to sculpt the sound of their spaces.  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.
