New and Improved Series II Wireless Surround Loudspeaker

So, we were sitting around the demo room one day engrossed in some action movie, with digital surround-sound effects flying all around the room thanks to a single SurroundBar®. Someone said: “Why not take the same technology that allows us to produce multiple front channels in a single speaker… and do it with the rear surround channels?” A challenge! Resourceful Polk engineers set about combining the benefits of two of our patented, state-of-the-art audio technologies, Controlled Dispersion Array (CDA) and Polk Digital Logic® (PDL). They also developed a unique cabinet design that works to enhance the effects of these technologies. Before you knew it, Polk had solved the age-old problem of surround-speaker wires cluttering up the sides of your room: A single, powerful, self-contained surround-sound loudspeaker system creates a completely enveloping, realistic surround-sound performance.

The F/X Wireless Surround Speaker Features:

A completely self-contained full range amplified surround-channel wireless sound system.

Plug-and-Play: Simply connect the compact transmitter to the rear-channel outputs of your processor. (High performance RCA connectors and speaker wire sets are included for your choice of easy transmitter-to-receiver connections.) The state-of-the-art 2.4GHz transmitter talks to the speaker’s onboard receiver, for instant, lossless signal response. No room-spanning wires!

Convincingly discrete rear-channel response thanks to Polk’s patented Controlled Dispersion Array (CDA) technology. CDA technology delivers realistic left, right, rear and surround staging for 5.1 (and beyond) systems, in any room environment and with virtually any placement.

Unique compact enclosure design and directed speaker array enhances the surround-sound effect. Plus, complex audio algorithms direct the drivers to work “out of phase,” creating a more spacious, enveloping surround effects experience.

Ported, for unexpectedly big couch-rocking bass response.

On-board 120 Watt multichannel amplifier.

Customizable settings for easy optimization with Polk Digital Logic, a 3-position DSP controller. Set it for your placement needs (floor, sofaback table or shelf mounts) and it automatically delivers perfect imaging and sound.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
