Bag End E-Trap
Electronic Bass Trap


The electronic bass trap, while not likely to replace all passive bass trap implementations, offers a precise tool to attack the very worst problems with a high degree of effectiveness in a fraction of the space.  It also offers a practical low-cost solution to existing rooms where problems are present and room re-design or large passive absorbers are not an option.

The Bag End E-Trap can be viewed as an electronic acoustic absorber.  It incorporates a feedback control scheme into a loudspeaker making the speaker exhibit the same dynamics as that of a reactive absorber.  Because it is active it is capable of adding considerable damping to a room and still be very small in size (18" x 13" x 10").  The small size allows the designer to place it in acoustically strategic locations without effecting the rooms upper frequency characteristics or impacting floor space and cosmetics.

The E-Trap offers precise tunability of two target frequencies simultaneously.  The frequency and amount of damping is adjustable via controls. PC measurement software (for Windows) is included with the E-Trap to allow the user to pinpoint the frequency that requires damping.  Once the E-trap is placed and tuned, it requires no additional attention.

The precision, ease of tuning and small size offered by the E-trap provide an additional tool to absorb low frequencies and can provide a dramatic improvement in the sound of the room.
