Add enhanced bass to your movies and music with the black Polk Audio DSW PRO 440 8" 180W Subwoofer. This subwoofer features an 8" polypropylene woofer and delivers up to 180W of power. With a frequency response of 30 to 125 Hz, the DSW PRO 440 is equipped to handle a variety of listening material. The included wireless remote control lets you adjust the subwoofer's volume, phase (0, 90, 180, 270°), and sound mode. For installation flexibility, LFE, line level, and speaker inputs and outputs are onboard. Additionally, the subwoofer can be installed in either down- or front-firing configurations.

Dynamic Balance

This technology combined with Polk Audio construction techniques help produce powerful, deep bass performance.

Klippel Distortion Analysis

The Klippel distortion analyzer is designed to optimize the motor structure, voice coil alignment, and suspension to help deliver efficient performance at all volumes.

Ported Design

The slot-loaded port, lightweight polypropylene cone, and rubber surround are engineered to produce enhanced volume, damping, and distortion-free bass response. This port design helps add more port surface for deeper, smoother bass response, even in a smaller cabinet size. The port is also tuned to minimize unwanted chuffing and air turbulence at the mouth of the port to reduce overall distortion.

Augmented Efficiency

The intelligent amplifier design helps reduce heat and power requirements, even at high volumes and in standby mode.

Night Mode

Lower the subwoofer's intensity right from the included remote control.

PRO Technology

Polk Room Optimizer (PRO) features four-way phase selection, four presets, and a blue status LED so you can adjust the subwoofer as you like without leaving your seat.

Feed Forward Distortion Suppression Technology

This technology sets the performance limit close to the actual theoretical maximum output of the subwoofer, with virtually no excessive distortion or damage.

Versatile Design

The DSW PRO 440 can be installed either in a downward-firing or front-firing orientation by simply changing the position of the feet, allowing for versatile placement, including inside audio furniture or a rack system. With the bass port on the same side as the woofer, you can just aim it where you want the sound to go.

Additional Features

  • LFE and line level inputs & outputs and 5-way binding posts for speaker level inputs and outputs provide easy connection to nearly any system
  • Designed to blend in with systems composed of other Polk speakers
  • Adjustable rubber feet for hard surface flooring and adjustable carpet spikes provide more placement flexibility
