Product Research

Overview: The Polk SurroundBar is a great solution for surround sound in situations where you can't, or choose not to, run speaker wires for a multi speaker system. Located above or below your TV, five surround channels (front left, center, front right, rear right, and rear left) are housed in this one speaker. Each channel can handle up to 125 watts RMS.

Driver Technology

SDA Surround technology: Polk's patented SDA Surround technology means there's no need to install rear speakers. SDA Surround creates a completely immersive experience, as if there were dozens of speakers all around you. This technology is based on fundamental research into the way our ears process sound and perceive the direction of sounds. It uses a patented combination of signal processing and acoustical geometry that complements the spacing between your ears to produce surround sound without the need for rear mounted speakers. Since the SurroundBar works directly with the hearing mechanism and requires no special room characteristics, it can deliver a room-filling surround experience in nearly any location in almost any type of room.

Enclosure: The SurroundBar features a stylishly curved anodized aluminum enclosure with gray trim. The shape of the heavy-duty non-resonant aluminum enclosure breaks up internal standing wave resonance to give you pure, lifelike sound.


  • Woofers: Seven 3-1/2" Mineral Filled Polymer Dynamic Balance woofers provide clear, distortion-free midrange, even at high volume levels
  • Tweeters: Three high-performance 3/4" Dynamic Balance Silk/Polymer Composite dome tweeters deliver clear highs and lifelike imaging


Speaker Terminals: The SurroundBar has five high-quality 5-way binding post input terminals, one each for front left, center, front right, rear right, and rear left channels. In addition to pin, spade, banana, and dual banana connectors, bare wire up to 11 gauge will fit. You will need to remove a plug inserted in the center of each post if you wish to use banana plugs.

Color Coded Wiring: The included 15-foot 10-conductor speaker wire is color-coded to match the SurroundBar terminals and clearly marked for easy hookup.

Mounting Options

Video Shielded: The SurroundBar is magnetically (video) shielded for safe placement near your TV or computer monitor without causing picture interference.

Cradle: The speaker can be placed above or below the TV using the speaker cradle. While on the cradle, the speaker can be aimed up or down slightly toward the listening area. The cradle lifts the speaker approximately 1/2" above the surface on which it sits.

Wall Mounting: The wall mounting system consists of two pieces; a wall mounting plate and a speaker mounting bracket. First, the plate is mounted to the wall, it's 20 inches long and has multiple holes so you'll be able to mount it to at least one stud (use two if possible). Mounting screws should be used with a wall anchor if not in a stud. Next the Speaker mounting bracket is bolted to the SurroundBar using the supplied 3/8" bolts. The speaker can be tilted up or down approximately 15° when mounted on the bracket. The bracket mounts the speaker approximately 1/2" away from the wall. The two 3/8" threaded inserts are 13" apart and can be used with different mounting brackets if you prefer.
