ASC QuarterRound TubeTrap IsoThermal

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.

What About Those Built-in Acoustics?

You may or may not know that some “TubeTraps” are not round, nor are they Tubes! The original, authentic, archetypal TubeTrap is still a cylinder and contains all the elements of room acoustic control that we hold dear. But the application of an RC-time constant lumped parameter acoustic bass trap can be-and has been-applied to many shapes, sizes, and geometries. Enter the QuarterRound TubeTrap.

What is a QuarterRound TubeTrap?

Similar to the classic cylindrical TubeTrap, a QRTT utilizes a flow-resistive membrane surrounding a capacitive air volume to increase efficiency of low frequency sound absorption. Just like it is with its tubular brethren, a larger internal volume permits operation to lower frequencies. And just like the classic TubeTraps, each QRTT contains a built-in treble range polycylindrical diffuser. The icing on the cake: because its shape is that of a quarter-cylinder, each one only takes up one quarter the space of the full-round model, despite operating across the same frequency range! Shown below is a cross-section of a QuarterRound TubeTrap, which is similar to full-round and HalfRound, but instead is shaped like a quarter-cylinder.
