Polk Audio's R30 floorstanding speaker furthers the company's tradition of using high-quality materials and excellent engineering to deliver exceptional sound and exceptional value. Its slim, tower design conserves floor space (occupying less than 1 square foot), and it's ideal for both movies and music. The speaker is sold individually, so be sure to pick up 2 for a stereo arrangement, 4 four front and rear left/right, etc. The speaker features Polk's exclusive Dynamic Balance drivers for wide frequency response and low distortion in both its .75-inch dome tweeter and its single 6.5-inch cone woofer.

Dynamic Balance started with laser interferometry research done in partnership with the Johns Hopkins University. Full-field laser-imaging research allowed Polk to view a driver's entire vibrating surface, revealing the resonance that develops on speaker cones as they move. That resonance is the root cause of frequency-response distortions. Knowing this helped Polk engineers find the right combination of materials, geometry, and construction techniques to tune out the offending resonance. The resulting Dynamic Balance technology produces flat frequency response, sharp detail, sonic transparency, and a speaker's ability to play dynamic programs at life-like levels without a hint of strain.

All woofers and tweeters in Polk home speakers feature Dynamic Balance technology, giving them a shared sonic signature for coherent, seamless sound even when you mix models in configuring your home theater. The drivers' wide dispersion means they project sound over a wide area, so every listener in a room will hear open, "box-less," three-dimensional sound.

A front-firing bass port confers high efficiency and powerful bass response. The speaker's arched grille eliminates grille interference with the port output, lowering turbulence and distortion while giving the speaker a cool look. Supplied carpet spikes ensure mechanical stability on carpeted floors for precise bass output and superior "imaging."

Magnetically shielded for safe placement near TVs and computer monitors, the speaker offers convenient, high-quality 5-way binding post terminals to accommodate several wire hook-up options. All Polk's R Series loudspeakers are perfect for building starter surround systems or for small-room or multi-room settings. With the addition of a PSW Series powered subwoofer, you can build an impressive home theater on a limited budget.

The LSi is for a serious listener; the person who really enjoys music, who sits down and really intently listens to his stereo system. Maybe this person already owns Polk Audio speakers, or has owned Polk speakers in the past, and has always felt that they wanted something 'tweakier.' This person could be a serious home theater enthusiast, too. They want to hear every detail a movie soundtrack has to offer. There's no question these speakers play loud, but new high-definition audio formats like Super Audio CD and DVD-Audio demand a new level of performance. The LSi is for the listener who is more interested in quality over quantity.

A perfect sonic and stylistic match for flat-panel and shallow-case TVs, the Polk Audio SurroundBar is designed to offer elegant, high-resolution, single-source surround sound. It comes with everything you need to mount it above, below, or even on your television, and it works with any surround sound receiver. It's an ideal listening system for anyone seeking rich, enveloping surround sound without the space commitment or hookup hassles of a multispeaker system.

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.
