POLK AUDIO

OUR TECHNOLOGIES

Great Sound for All starts with great engineering.

At Polk, we believe that Great Sound for All starts with great engineering, which is why we've spent more than 50 years researching and refining the technologies that deliver rich, immersive sound that reveals every nuance of your favorite music, movies, and games.

VOICEADJUST

Polk’s patented VoiceAdjust technology lets you sharpen dialog at the push of a button without raising the volume of background music and effects.

PINNACLE RING TWEETER

Our Pinnacle Ring Radiator tweeter features a pointed waveguide that reproduces highs with pinpoint accuracy, while spreading sound evenly throughout the room for the same authentic sound in every seat.

TURBINE CONE WOOFER

Polk's Turbine Cone solves a classic design dilemma: how to make a driver cone that’s both rigid and moves air efficiently, for the most powerful, accurate sound. Innovative fin-like ridges make Turbine Cone extraordinarily light and stiff, achieving breathtaking midrange detail even at high volumes.

POWER PORT

Polk’s patented Power Port technologies strategically guide air out of the speaker enclosure, reducing noise and distortion to deliver cleaner, more powerful bass and a more defined midrange.

COLUMN RESONANCE CONTROL

At Polk, we take many steps to tame cabinet resonance, using low-resonance materials and angled bracing that breaks up sound paths. Our Column Resonance Control technology takes things even further, adding an absorber that neutralizes natural resonances in large cabinets. The result is more accurate sound with smoother, cleaner bass and midrange.

DOLBY ATMOS

Dolby Atmos puts you at the center of your entertainment, delivering 360-degree sound that is spacious, enveloping, and stunningly lifelike. We offer a range of Dolby Atmos-certified sound systems, from compact sound bars to full component systems.

STEREO DIMENSIONAL ARRAY (SDA)

When you listen to two speakers, sound from the left mixes with the sound from the right, making music seem less realistic. Polk’s patented SDA technology adds a second set of drivers that cancel out the “mixed” sound, leaving true stereo sound that comes to life with extraordinary depth and spaciousness.

HI-RES AUDIO CERTIFIED

Hi-Res Audio certification verifies a speaker's ability to accurately reproduce high-resolution digital audio, which offers more detail and depth than standard digital audio. With Polk’s Hi-Res Audio certified speakers, you can be confident that music, movies, and games will sound as close as possible to their original sound.
