This Instant Home Theater is about more than creating sound far beyond what any TV speakers can produce. The 9000 is about transforming your flat panel into an amazing home theater experience. Polk technology and innovation make this possible. For starters, youll hear superior center channel intelligibility thanks to the Optimized Center Array, a feature that employs all of the bars drivers. Then, like real component systems, we use the critical 80Hz crossover point for bar and sub to minimize localization of the sub and create the ideal blending. But perhaps most impressive, weve created a component quality sound bar that reproduces true 5.1 channel audio in DTS or Dolby Digital. When you augment those surround formats with our proprietary SDA® Surround Technology, youll hear why the SurroundBar 9000 IHT is the best sounding bar/subwoofer system.
