Quarter Round TubeTraps give you very high performance in a form-fitting package, custom design to fit in the corner when space is at a premium. All Quarter Round TubeTraps are built with our patented ISOTHERMAL technology. 2x bass absorption than our Standard TubeTrap line.
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.
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.
