Bag End ISUB2-18 18” Infra Self Powered Subwoofer System

Bag End's ISUB2-18 brings 700 watts of power and integrated bass management to professional surround systems in critical applications like mastering labs, recording studios, and post-production.

Two female XLR inputs are combined into a mono summed output that drives a front-firing 21" loudspeaker in a sealed box. The ISUB2 provides a flat frequency response down to 8 Hz for the kind of bass can feel. If a stereo bass system is desired, a pair of ISUB2-18s can be used separately.

The ISUB2's dual integrator will perform the upper roll-off from the full-range input signal. this provides a more accurate reproduction than an in-line low pass filter placed before the inputs would provide.
