The Scan-Speak Revelator 32W/4878T11 Woofer represents the pinnacle of bass driver engineering, designed to deliver deep, controlled low frequencies for the most discerning audiophile systems. As part of the celebrated Revelator series, this 32 cm subwoofer is purpose-built for high-end home audio, studio monitoring, and custom loudspeaker projects where accuracy and authority are paramount. Whether employed in a sealed enclosure for tight, articulate bass or a vented design for extended low-end reach, it excels in reproducing everything from subtle double bass nuances to thunderous cinematic effects with remarkable poise.

Technically, the driver boasts a total Q factor (Qts) of just 0.21, ensuring a critically damped response that minimises overhang and distortion. The combination of a low electrical Q (Qes: 0.22) and a higher mechanical Q (Qms: 4.25) yields exceptional transient speed and control. With a sensitivity of 95 dB SPL (1m/2.83V) and a linear excursion (Xmax) of 7 mm, it produces substantial output with minimal compression. The 3.1 ohm DC resistance and 0.36 mH voice coil inductance further enhance power handling and clarity. Housed in a robust chassis with a 292.5 mm cutout diameter and 168.5 mm depth, this woofer integrates seamlessly into premium designs. The Revelator 32W/4878T11 is the definitive choice for those who demand bass that is both powerful and precise.
