Overview Built-in center speakers let you enjoy 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 Infrared type rear speakers for full surround sound and easy installation The rear speakers supplied with this speaker system use an infrared receptor to receive signals from the front speakers so you can have a complete home theater that lets you enjoy the maximum surround effect without a profusion of unsightly speaker cords. 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 left and right front speakers to form a DBR super woofer system. Front view Left speaker Center channel speakers Center channel speakers Right speaker Main duct Chamber Drive unit aL Super woofers Rear speakers How the center speaker works The front left and right speakers are equipped with center channel speakers (see above) angled inwards at 15° to reproduce the center channel sounds. 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 main 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 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
