Overview Dolby Pro Logic Surround sound The use of a center speaker is a key factor in obtaining a full surround effect when playing sources encoded with the Dolby Pro Logic Surround sound system. Center speakers in a movie theater make central sounds, such as dialogue, clearer and create a unified sound image. Normally, you have to install a center speaker separately, but this speaker system makes it easy to set up a high-performance home theater system by incorporating a high-quality center speaker system into the front speakers. Top view Dynamic Bass Roar (DBR) super woofer system provides theater-like bass sound To provide a theater-like experience complete with dynamic bass sounds, this speaker system incorporates the Super Acoustically-loaded Woofer (SAW) design (see below) in the right front speaker to form a DBR super woofer system. Chamber Drive unit Duct Front view Left speaker Center channel speakers Center channel speakers Right speaker 0 Super woofer I Rear speakers How the center speaker works The front left and right speakers are equipped with center channel tweeters (see above) angled inwards at 30° to reproduce high-frequency center channel sounds. Lowfrequency center channel sounds are mixed with the front channel signals and reproduced through the front left and right full range units. This design produces a high-quality centralized sound image for the center channel which exactly matches the quality of the front channel sound to provide superior sound quality and a unified sound image without a cumbersome external center speaker. What is the SAW design? The SAW design features a centrally-positioned woofer drive unit, two chamber construction, and a long duct. Through precision control of the acoustics of the two chambers, the unit can reproduce powerful ultra low frequencies without muddiness. In addition, we also included two super woofer modes designed to bring the dynamic bass sounds found in movie theaters (mode 1) and concert halls (mode 2) to your living room. Power turns on and off automatically The speakers will turn on automatically when a sound signal is input and turn off when you've finished watching a program and the sound signal goes out. So you don't have to bother using the power switch every time you use the system. 5
