XB Subwoofers

Power Subwoofers featuring BassTrac®

Our new XB Subwoofers offer a clean,contemporary style that is visually more compatible with modern interiors. New style elements include a lower,slightly wider footprint,gently rounded corners,metal grilles,and flush-mounted volume controls on top of the XB8,XB6,and XB4.All are available in black ash.All four are front-firing, front-ported, and very easy to install.

The XB subwoofers are equipped with Deep Channel™ woofers that deliver extended excursion with increased bass response, and Boston’s exclusive BassTrac circuitry,designed to eliminate distortion. A 24dB/octave lowpass filter on each subwoofer prevents it from being easily localized by ear, increasing placement flexibility. Also provided are variable crossovers, phase controls, rear-panel line and speaker level inputs, and a crossover bypass function for Home Theater components that perform their own bass management.

The XB8 and XB6 powered subwoofers feature large 12-inch Deep Channel woofers, BassTrac circuitry, and powerful amplifiers in vented enclosures. The XB8 has a FTC-rated 300-watt amplifier and the XB6 has a 200-watt amplifier. The XB8 and XB6 have a frequency response (+/-3dB) of 26Hz- 150Hz and 29Hz-150Hz respectively. The volume control is mounted on top of the cabinet, flush with the surface, so the top remains perfectly flat.
