    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.


    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.
    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 3 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.

    What's in the Box
    SurroundBar speaker, 2-piece wall bracket, a center-channel base, mounting screws, 25-foot wire bundle, and a quick-start guide.

    I purchased the Polk Surroundbar with some trepidation, as it is an expensive leap of faith purchase due to the fact that I was unable to find a local Polk dealer with a showroom model to test. I thought the unit would be ideal in my TV room due to the fact that I refuse to drill holes in my hardwood floors to accomodate traditional 5.1 rear speakers.

    Fit and Finish -

    The Surroundbar arrived and I was immediately impressed with the integrity of the product packaging. The fit and finish of the bar itself is very impressive. The product is very heavy and solid, encased with a real metal finish, giving it a very hi-tech and sturdy appearance. In addition, the accessories included in the box (stand, mounts, cables) are of the highest quality and complement the surround bar nicely.

    Performance -

    When the system was initially set up, I thought it sounded ok. Then I further studied the set-up guide and found that the way my subwoofer was connected and some of the necessary settings on my receiver were incorrect. Instead of the standard RCA type sub connection, I rewired the sub to be in line via speaker wire to the 2 front connections as reccommended by Polk. Also, the speaker size needed to be set to large for all channels. (I've learned to ALWAYS follow the manufacturer's specifications!)

    Once the adjustments were made, the sound was incredible. The first thing you notice is the overall power of the unit. The sound is huge and imposing. The surround effect is absolutely incredible both with DVDs and Xbox games. I now have almost a full 360 degree sound experience with distinct separation between all channels. Movies with DTS-ES 6.1 sound are a wonder to listen to. This system replaced a 3.

    For what it is designed, the speakers are top notch.

    Pros:

    The pros are fairly obvious: space saving, great look, no cumbersome wiring, the surround effect is clearly separated, AND it is NOT dependent on room configuration.

    Additional pro is the sound quality: Mid range is wonderful, jazz and vocal sounds have the fullness you'd expect from Polk Audio. Treble is crisp without breaking. All-in-all, the sound is sufficiently top-notch even for someone who appreciates good sound systems (except for some of you serious audiophiles).

    Another pro is the speakers are strong enough to handle enough power for a sizable room, say a 20x20 room.

    Cons:

    The cons is pretty obvious too. It is not real surround, so it does NOT give 360-degree feel to the sound field, but rather gives about 180-degree feel.

    Note that you will need to add your own subwoofer that has sufficient power for your room size.

    Bottom line, I am very happy with this purchase.

    I've been a home theater buff for years now, and have only had "true" 5.1 or 7.1 surround setups, with obligatory wires everywhere and unhappy wife as a result (wives I'm convinced care little about home theater, just it works is about it...!!). But I hate looking at wires as I get older, and prefer my current home to be as wire free as possible. The super low roofline makes running wires in the attic to the edges of the room virtually impossible, so my only real option was either wireless or a surroundbar setup. Unless you plan on spending a mint, wireless speakers are pretty good at being surrounds or iPod accessories but that's about it. There's just not that certain sound you get from a hard wired speakers. Wireless rear speaker setups are a better option, where you have one receiver and two mini-amps connected to the rears. But I digress...My decision after reading the reviews on the SurroundBar from Polk was to try it out and keep the room clean of wires. It does sound fantastic, no doubt. No, you will not get the same effect as you do with speakers that are behind you. Your room dynamics will affect how the speaker sounds granted, my parlor room is a near perfect cube and pretty large. I will add some wireless rears and run a 7.1 surround setup, since I have the amazing Onkyo TX-SR576S receiver (new also). Get the matching Polk PSW10 sub, or a similar 10" forward firing sub. An 8" is too small to balance out with the SurroundBar effectively.

    The speakers are great, but I was disappointed that Amazon (ordered direct) sent a package that had obviously been previously returned, contained the wrong manuals, and was missing the hardware necessary to attach the speaker to the wall mount bracket. It seems there wasn't even an attempt to QC the package prior to sending out to the next customer. :(

    Plain and simple, we had an ongoing problem. He loves big sound and I hate wires running all over the house. When we recently purchased a new television set decided to give this a try. We already owned a sub-woofer so hooked this into the stereo receiver, connected the television and dvd - great sound, no ugly mess of wires and easy installation.

    Like others have mentioned, use the instructions. We originally attempted a different configuration and the results were inferior....in fact, we thought something was wrong with the speaker so took the time to review everything, realized our mistake and were very pleasantly surprised by the superior sound quality.

    While others have complained about the lack of "true surround" from not having speakers physically placed behind you, I find this quite superior. At least to my sensory input, I've always hated the "disconnect" between seeing something on a screen in front but hearing it behind you. This provides a much more realistic sound quality in that it totally wraps around the room in much the same way that typical sound does. Lows and low, highs are high and the rest is very crisp clean sound. Best of all - banished the wires.
