Exclusive Polk Power Port for Effortless Bass

Power Port is a Polk-patented design that smoothly transitions the air flow from the speaker's port into your listening area. It also extends the overall bass port, providing greater surface area to eliminate turbulence and distortion for louder, deeper, more musical bass impact. On average, Power Port provides 3dB louder bass output than conventional ported loudspeakers.
