All XB Subwoofers deliver The Boston Sound; the sound the artist intended. Pure, natural, true-to-the-original performance(R).
Boston Acoustics’ 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(TM) 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.
