Extra Info:


Bag-End are a well respected pro-audio company that has somewhat of a legendary following from what I can see. The E-trap is the first device of its kind. It is what looks ostensibly like a small subwoofer that sits in a hidden corner of your room and uses a built in microphone and special circuitry to reduce standing waves in your room. It is very effective (as you will see from my thread below and as you'll read in the reviews on the web). It takes the place of large passive bass traps and can be more effective than even large bass traps especially in rooms with very sharp peaks and dips at defined intervals. Unlike DSP, it affects the bass resonance over time not just intensity. I also found that it can fill in dips as well as smooth off peaks.

Given it's mottled black paint finish and smallish dimensions it can be placed in a corner or against a wall to form a discrete but effective solution to bass modes.

This is the permanent-install version of the unit. It doesn't have the ugly handle on top and it only has one microphone.
