A Polk Power Port minimizes turbulence, reducing noise and distortion that mask midrange clarity. Its front-firing configuration means accurate bass no matter where you place your subwoofer.
High-resolution 32-bit floating point processing with group delay-minimizing filters and precision limiters enables clearer bass with crisper transients.
Time-Smart Phase Control provides 360 degrees of phase adjustment centered around lowpass filter settings, ensuring precise system blending. Adjust polarity in 45-degree increments, displayed on LED indicators.
An adjustable 4th-order lowpass filter provides precise frequency control, for seamless integration with main speakers and superior overall system performance with open, balanced lows and mids.
