Bowers & Wilkins Active closed-box subwoofer system

ASW 750 The ASW750 is technically similar in concept to the ASW700, but offers higher output and deeper bass due to its larger driver, higher power amplifier and larger cabinet. The 300mm (12 in) driver can move large volumes of air with exquisite control for accurate low-frequency output. The powerful 1000W amplifier, coupled with the larger driver provides a maximum output level over 4dB higher than the smaller ASW700. The cabinet is extensively braced and available in the same real wood veneers as the rest of the 700 Series.
