SurroundBar Series

Polk Audio SurroundBar: The Polk Audio SurroundBar 400 CHT is a completely self-contained passive soundbar speaker, measuring a mere 2.5" deep. The Polk Audio SurroundBar 400 CHT achieves single-speaker surround sound from one slim speaker bar. Polk Audio's exclusive patented SDA Surround & Polk Digital Logic technologies eliminate the need for rear speakers. The SurroundBar 400 CHT can be table-top or wall mounted.

7Ch, 5Ch, or LCR Switch: The Polk Audio SurroundBar 400 CHT features a channel mode switch, which enables the SurroundBar to play as part of a 7ch, 5ch, or LCR front stage. You get a rich, enveloping surround experience when you using the SurroundBar 400 CHT in 7ch or 5ch mode, plus the flexibility of adding dedicated surround channel speakers when you use it as a LCR front stage.

• 7Ch Mode: In 7ch mode, the Polk Audio SurroundBar 400 CHT creates all 7 channels of surround (Front/Center/Surround/Surround Back), without the use of any additional rear speakers.
• 5Ch Mode: In 5ch mode, the SurroundBar 400 CHT creates 5 channels of surround (Front/Center/Surround), requiring additional speakers for the surround back channels.
• LCR Mode:  In LCR mode, the SurroundBar 400 CHT creates 3 channels of surround (Front Left/Front Right/Center), requiring additional speakers for the surround & surround back channels.

Driver Technology

Polk Audio Proprietary Technologies: The SurroundBar 400 CHT utilizes Polk Audio's proprietary SDA Surround & Polk Digital Logic processing technologies to produce a rich, enveloping listening experience.

• 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 5 or 7 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 400 CHT 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.
• Polk Digital Logic: The SurroundBar 400 CHT utilizes Polk Digital Logic to deliver big, crisp sonic performance with no complicated setup or calibration. Through Polk Digital Logic, the SurroundBar 400 CHT's sound is created independent of any room boundaries. Polk Digital Logic helps to maintain a solid center channel for clear, intelligible dialogue, & Polk's signature warm & full sound.

Polk's Next Generation of Dynamic Balance Drivers: The SurroundBar 400 CHT uses Polk's next generation of Dynamic Balance composite polymer mid-woofers. Seven 2.75" (diameter) drivers incorporate rubber surrounds & powerful neodymium magnets for low distortion. Four of the seven drivers are dual voice coil (DVC) designs that make possible reproduction of seven discrete channels of information from fewer drive units than would otherwise be necessary. Fewer drivers enable Polk to reduce the bar's internal volume & therefore minimize the bar's depth, while reproducing seven vivid full-range channels associated with state of the art home-theater processors.

Silk Polymer Dome Tweeters: Three 0.75" silk polymer dome tweeters are employed for smooth response & exceptional detail.

Frequency Response Note: The overall frequency response is 90 Hz to 27,000 Hz & the -3dB frequency response is 110 Hz to 26,000 Hz.

Enclosure Design

Aluminum Enclosure: The SurroundBar 400 CHT features a stylishly curved extruded aluminum enclosure in a high-gloss black to match today's flat-panel televisions. The shape of the heavy-duty non-resonant aluminum enclosure breaks up internal standing wave resonance to give you pure, lifelike sound.

Anti-Diffraction Grille & Bezel: The SurroundBar 400 CHT's anti-diffraction grille & bezel help create open, spacious imaging.

Connections

Speaker Terminal: The SurroundBar 400 CHT is fitted with a 14-pin proprietary connector to attach the included 15' speaker wire harness.

Color Coded Wiring: The speaker wire harness is terminated with a proprietary 14-pin connector on one end & 14 bare tinned wires on the other end. The included 15' 14-conductor speaker wire harness is color-coded for easy identification when connecting to your home theater receiver.

Mounting Options

Placement: The Polk Audio SurroundBar 400 CHT can be placed in front of, below, or above your flat-panel television.

Rubber Feet: The Polk Audio SurroundBar 400 CHT speaker can be placed on a stand or shelf using the included rubber feet. The rubber feet simply slide into the bottom grooves of the SurroundBar speaker. The feet can be positioned to place the speaker flat or at a 10° upward angle. Without the feet, the SurroundBar speaker tilts up 5°.

Note: The rubber feet add 0.125" to the height of the speaker.

Wall Mounting: The SurroundBar 400 CHT's can be hung on the wall using the supplied wall-mount bracket. The included wall-wall mount bracket clips on the back of the SurroundBar speaker without any additional hardware. The mounting bracket should be attached to the wall using a minimum of five drywall or wood screws (sold separately). Make sure the bracket is stud mounted.

Note: The mounting bracket measure 22.75" wide. The bracket adds 0.125" to the depth of the speaker.
