Polk Audio DSWPRO550wi Features

• You never have to leave your seat while you adjust your subwoofer to its optimum performance level thanks to feedback from the blue status LED, four-way phase selection for easy blending with your main speakers and full control of the Polk Room Optimizer (PRO)
• Simply hook up your Polk PWSK-1 wireless transmitter conversion kit (sold separately from the subwoofers), then turn on your receiver, the transmitter and your subwoofer; no additional AC power connection is necessary, because the dongle connects to the amplifier's existing power supply
• LFE, line level inputs and outputs and 5-way binding posts for speaker level inputs allows easy connection to any system
• DSWPRO550wi enclosure is designed and engineered for perfect volume, minutely tuned for distortion-free low frequencies and internally braced and damped to eliminate internal standing waves and other performance-robbing resonances
• The "Night Mode" setting temporarily lowers the sub's intensity with a quick and easy toggle from the remote control
• Polk intelligent amplifiers require less power to sound great, use power more efficiently and know when to stand down (especially at low volumes or in "Standby" mode); even at extreme listening levels, it's a wonder of digital high efficiency, bullet-proof reliability and minimal heat generation
• DSWPRO550wi subwoofer blends perfectly with systems composed of other Polk loudspeakers
• Feed forward distortion suppression technology enables us to set the performance limits much higher than normal, much closer to the actual (theoretical) maximum output of the subwoofer, with no risk of excessive distortion or damage
• Use adjustable rubber feet for hard surface flooring or adjustable carpet spikes for carpet; both options give you more placement flexibility and a totally dependable, more efficiently stable setup
• The state-of-the-art Klippel distortion analyzer optimizes the woofer's motor structure, voice coil alignment and suspension for smooth for unimpeded movement over a broad spectrum of the lower frequencies to ensure the best, most efficient performance even at extreme listening levels
• DSWPRO550wi subwoofer can be arranged with their feet forward or down, for standard downward-firing position or innovative front-firing mode (you can snap on the grille and it looks smart) that lets you can place the subwoofer just about anywhere, even inside audio furniture or a rack system
• The unique slot-loaded port design of the DSWPRO550wi adds significantly more port surface area, for deeper, smoother bass response even in a smaller cabinet size, plus special tuning eliminates unwanted chuffing and air turbulence at the mouth of the slot-loaded port, for distortion-free bass
