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
- 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.
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
