High-powered amplifier
Provides power and control to deliver impactful bass that fills the largest rooms, offering definition, dynamics, and clarity at any volume.
Forward-firing long-throw woofer
A front-facing, high-excursion 12” woofer produces deep, defined lows down to 18 Hz. It’s the difference between bass you hear and bass you feel.
Acoustically optimised cabinet
A rigidly built, ported cabinet is reinforced with FEA-optimised internal bracing that minimises resonances and colouration, ensuring clean, effortless reproduction of low-frequency detail.
Larger-than-life bass with unrivalled precision
DUAL POWER PORTS
Two Polk Power Ports minimise turbulence, reducing noise and distortion that mask midrange clarity.
ADVANCED DSP
High-resolution 32-bit floating-point processing with group delay-minimising filters and precision limiters enables clearer bass with crisper transients.
TIME SMART PHASE CONTROL
Time-Smart Phase Control provides 360 degrees of phase adjustment centred around lowpass filter settings, ensuring precise system blending. Adjust polarity in 45-degree increments, displayed on LED indicators.
4TH ORDER LOWPASS FILTER
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.
An auto-sensing power supply reduces power consumption when the subwoofer is not in use.
