Patent Pending Technology

Developed especially for the F/X Wireless Surround, Controlled Dispersion Array is comprised of two tightly grouped speaker arrays, in combination with phase and amplitude tapering, that produces a radiation pattern of narrow beams. CDA permits the F/X to project sound toward reflective surfaces to produce an immersive, spacious surround field, rich with spatial cues required for proper localization of surround sound effects.
Polk Digital Logic is a sophisticated processing algorithm that enables the F/X Wireless Surround to reproduce accurate and believable surround sound irrespective of your listening position relative to the speaker. This means you can place the F/X Wireless Surround on the floor, the table or up on a shelf, and at the push of a button give your ears the cues they need to locate the surround images in space.

1To ensure a valid warranty, Polk loudspeakers must be purchased through an Authorized Polk Audio home or car loudspeaker Dealer (such as Amazon.com). (If you're not sure a dealer is "authorized," call Polk Audio at 1-800-377-7655, and ask us.) The warranty is not transferrable, that means it applies only to the original purchaser. If you purchase your speakers from a private individual, that product is considered "used" and has NO factory warranty, no matter what the seller implies. The warranty is VOID if the serial number of the speaker has been removed or defaced. If you have any questions about your warranty coverage, or you think you need service, call Polk Customer Service at 1-800-377-7655. We’re here to help you get the most from your new speakers!
