Patented SDA Surround Technology Delivers a Full Room of Sound
 Get professional surround-sound from a single speaker bar, regardless of your room's layout |
Our patented SDA Surround technology means there’s no need to install rear speakers. SDA Surround creates a completely immersive 5 channel surround experience, as if there were dozens of speakers all around you, all from a single, 43-inch long cabinet. No rear speakers are required. This technology is based on fundamental research into the way our ears process sound and perceive the direction of sounds.
The SurroundBar works in any room; SDA Surround is not dependent on your room's walls to produce the surround effect. 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 or special room characteristics.
Some other single speaker surround solutions bounce sound off of walls and require symmetrical rooms and un-cluttered side and rear walls to create a surround effect. Since the SurroundBar works directly with the hearing mechanism and requires no special room characteristics, it can deliver a room-filling 5 channel surround experience in nearly any location.
SDA Surround technology relies on a mixture of acoustical engineering, psychoacoustic principles and a little magic. The original SDA technology, developed in the early 1980's, was a two-channel technology intended to overcome a fundamental problem of stereo reproduction. SDA Surround utilizes the same basic principles but expands the technology to allow for reproduction of surround sound without the need for rear speakers. This technology requires no reflecting surfaces or special speaker placement and can be connected to any surround sound receiver. It will work well in almost any room of any size or shape and will deliver a surround sound experience for almost all listener locations. Because of the psychoacoustic principles on which the technology is based, SDA Surround achieves exceptional continuity side-to-side and front-to-back so that sounds closely follow the action suggested on screen. It also delivers consistent soundstage depth, even directly to the sides, a quality only achieved by the best conventional hard wired systems. This quality makes SDA Surround seem more like having dozens of speakers around you providing smoother and more immersive surround sound.
Innovative Design with Simple InstallationSeven 3 ½" Dynamic Balance Drivers and three ¾" Dynamic Balance Dome Tweeters deliver clear, natural midrange, high frequencies and lifelike imaging. An aluminum-extruded enclosure eliminates cabinet resonance. The anti-diffraction grille and bezel help create open, spacious imaging. And it's magnetically shielded, of course, for safe placement on or near TVs.
Installation versatility is designed in. You can wall mount the SurroundBar right below your flat-panel TV. Or use the included cradle on a TV stand, a shelf or for set-top placement. The Polk Audio SurroundBar is a welcome addition for anyone who wants all the thrills of surround sound…but none of the hassles or clutter.
