TubeTrap™ Technical Details

TubeTrap is an acoustic circuit and an RC time-constant bass trap with acoustic crossover into a treble range diffuser. TubeTrap is the only bass trap with 2.5 octaves of smooth absorption and 4.0 octaves of smooth tunable treble diffusion.Unlike any other bass trap, the physics behind the TubeTrap are based on a capacitive-resistive circuit. The acoustic capacitor (C) is the air chamber inside. The bigger it is, the more efficient the TubeTrap is at low frequencies. The acoustic resistance (R) is DC impedance matched to the radiation (LC) impedance of a freely radiating soundwave. Because of this design feature, the TubeTrap is more than 100% efficient.

Another unique feature is the adjustable diffusion grid built into the TubeTrap. The specular diffusion panel that covers half of the TubeTrap is an acoustic choke (L) which is sized, ported and mass loaded to backscatter the treble range.

Audiophile listening room acoustics with TubeTrap bass traps including absorptive/diffusive grid on walls, bass traps in corners behind speakers, image and soundstage trap between speakers and the classic acoustic Persian carpet.

Here's an example of front-end control in this room with all concrete wall and wood floor. There's a suspended acoustic ceiling, upper traps are not needed, just the lower half of the room needs to be controled.
