The only subwoofer that can challenge the mighty P18, the V6 from Procella delivers essentially indistinguishable performance in a tall form factor enclosure that is a mere 11.8 inches deep. Six 10 inch very high output Italian pro audio drivers are mounted in Procella’s V6 push-pull configuration, which produces high-definition low frequencies, even cancelling even-order harmonic distortion. The V-shaped enclosure and driver coupling increases efficiency to an extraordinary 99dB @1m/1W. It’s incredible maximum output of 137 dB is produced by 2,800 Watts of amplification using the DA2800-DSP power amplifier. Extending to below 18 Hz, this subwoofer is capable of massive output in even the largest theaters and screening rooms!
