Description of Polk Audio AM4055-C SurroundBar Speaker (Black)

The SurroundBar is designed to complete your high-definition TV experience and is a perfect match for flat-panel TVs. (Titanium color shown)

SDA technology projects sound to both sides and behind you.

Polk Audio's patented SDA Surround technology means there's no need to install rear speakers. SDA Surround technology is founded on extensive research into the way human ears process sound and perceive directionality of sound. Unlike speakers or surround algorithms that merely simulate surround effects, the SurroundBar reproduces discrete, multichannel surround sound using a patented combination of signal processing and acoustical geometry called Acoustic Wave Front Reconstruction (AWFR). Since the SurroundBar works directly upon your ears and requires no special room characteristics, it can deliver room-filling surround sound nearly anywhere.

As with conventional 5.1-channel systems, you'll hear the best surround effects when you're centered directly in front of the SurroundBar. However--unlike conventional 5.1 systems--the SurroundBar delivers surround sound regardless of how close or how far away you sit.

While it's technically a single speaker, the SurroundBar contains seven active drive units, three tweeters, and inputs for all five primary surround channels: front left/center/right and rear left/right. Multiple drive units spaced roughly the same distance apart as your ears allow the speaker to keep you from discerning the actual sound sources. Instead, it will seem as though sound is coming from all around and behind you.

Mount the SurroundBar below your flat-panel TV, or use the included cradle for a shelf or set-top placement. (Titanium color shown)

The SurroundBar's circuitry maintains proper isolation of all amplifier channels and will function correctly with any amplifier or receiver capable of driving a 4 ohm load (that is, capable of powering 4-ohm speakers). Many receivers are rated for maximum power into 8 ohms but function perfectly well--functioning with about half their rated power--into 4 ohms, too. Wiring a stand-alone powered subwoofer in line with the speaker (a procedure illustrated in the product manual) will heighten the sense of realism and visceral power of the SurroundBar.

For even more spacious sound, you can use the SurroundBar with your existing surround speakers, too. In such an arrangement you can wire the surround outputs from your receiver to your separate surround speakers instead of to the SurroundBar's rear-speaker terminals, using the SurroundBar for the front left, center, and right channels only.

Simplified color-coded hookup with five channels directly from the home theater receiver.

Better still, if you have a 6.1- or 7.1-channel receiver, use one of your surround speakers as the rear-center speaker in a 6.1 system, or both surround speakers as 2 of the 4 speakers in a 7.1 system (with the SurroundBar's 2 surround channels in filling in the sound for the other 2).

The SurroundBar must be mounted horizontally to function properly. Placement directly above or below your TV screen pointed in the same direction as the screen will give the best coordination between your surround sound and the on-screen images. Wall mounting, shelf mounting, table mounting, or stand mounting all work equally well. However, walls or other large obstacles within three feet of the sides of the SurroundBar will reduce the effectiveness of its surround delivery. Cross-corner locations will work just fine.

The supplied 25-foot, 10-conductor cable is color-coded and clearly marked for easy hookup.
