The Audison VOCE II AV 6.5 P II woofer is engineered to deliver exceptional sound clarity and precision. It naturally rolls off at off-axis positions, eliminating the need for a low-pass filter in most door installations and reducing phase shifts common with other filters. It can employ a gentle 6 dB/Octave filter to enhance low and mid-bass tones, further enriching sound quality.
