• All New Production TubeTraps Have the Isothermal Upgrade (classic version available on request) ASC's Patented IsoThermal TubeTrap delivers twice the bass absorption power as our original TubeTrap while following tradition by retaining a fully adjustable treble diffuser.  Isothermal TubeTraps are modular, self-contained, broadband acoustic absorber/diffusers that improve the quality of music playback. For decades Audiophiles & Recording Engineers have relied on the award-winning TubeTraps to get their room sound just right. Simply place them in the corners of your listening room or studio, and they go to work—giving you a clean musical bassline, along with added high frequency ambient sparkle.

  • ASC's Half Round TubeTrap Isothermal model is a versatile evolution of the TubeTrap, allowing the same sound-busting power of the TubeTrap to be wall or ceiling mounted. The unique and effective design of Half Round TubeTraps combine broadband absorption, diffusion, and directional control of sound reflections to reduce noise levels while maintaining room brightness and enhancing image resolution. This design approach results in compact and modular units that can be placed in patterns on walls, ceilings, and in corners of any room.
  • QuarterRound TubeTraps (QRTTs) give you very high performance in a form-fitting package, custom designed to fit in the corner when space is at a premium.  All QRTTs are built with our patented Isothermal technology, providing double the bass absorption as our Standard TubeTrap line. Like all ASC products, these are hand-built to order at our headquarters in Eugene, Oregon and are 100% USA made.

    For pricing, select from the variant options below. Typical lead time is 3-4 weeks.

  • The TubeTrap is the foremost corner-loaded bass trap in the audio industry. It was only natural that ASC would adapt the same technology to fit flush into corners, walls and ceilings. Half Round TubeTraps are a custom order product.
  • The Quarter Round TubeTrap Standard gives you very high performance in a form-fitting package, custom design to fit in the corner when space is at a premium. All models feature Isothermal construction

  • SuperTrap

    From $649
    Sometimes we need more absorption at a certain frequency or bandwidth than the standard TubeTrap for that same frequency range can provide. That’s when SuperTraps are called into play. SuperTraps are TubeTraps tuned to operate to lower frequency than their standard counterparts. They are standard TubeTraps whose interior has been fit with acoustic circuitry to reshape their frequency response curve in the bass range, creating more efficiency in one tuned bandwidth at the expense of efficiency in the sidebands.
