The center speaker makes dialogue and other centrally positioned sounds clearer and the sound image more unified. For this reason, true home theater systems use a center speaker equivalent in quality to the front speakers and positioned very close to the screen image. With its "enhanced theater mode speaker system", the SA-VAI offers a simple, high-performance home theater system that produces high-quality center channel sound with only two front speakers. In this system, high-frequency center channel sound is produced by center channel tweeters, situated in the front left and right speakers and oriented inwards at an angle of 30° (see diagram), and low-frequency center channel sound is produced by mixing with front channel signals and reproduction through the front speakers. The result is a high-quality center sound with the same high quality as the front channel sound, and a superior, unified sound image for maximum surround sound effect. The SA-VAI incorporates SAW-type super woofers in the front left and right speakers to form a DBR super woofer system. The SAW design features two inner chambers and a centrally-positioned super woofer drive unit. Through precise control of the acoustic characteristics of the front and rear chambers, the system reproduces ultra-low frequencies with high power and clarity. The SA-VAI features a SAW-type super woofer in both left and right front speakers, producing powerful sounds for impressive movie effects. 5
