Deep Bass from Patented* PowerPort® Technology
Exclusive PowerPort venting technology belts out the kind of rich powerful bass you'd expect from much larger speakers, eliminating the need for a subwoofer.
Bass ports reinforce sound created by the rear of the speaker cone into your room.
Sound that would otherwise be trapped in the enclosure. But conventional bass ports
lose efficiency and create distortion because of air turbulence at the mouth of the port.
PowerPort vastly reduces air turbulence at the port mouth thereby reducing distortion
and increasing bass output. This is the same technology used in Polk's legendary
$10,000 Signature Reference Theater system. The SurroundBar 360º's PowerPort
delivers rich and warm sound, making all of your music and movies sound natural
and life-like.
