HT-S990THX 7.1-Channel THX Certified Home Theater System

$1,099 MSRP

Setting the Quality Benchmark as the World’s First THX Certified Integrated Home Theater System

The HT-S990THX is the first system to meet the parameters set by THX for overall system performance as opposed to separate loudspeaker and amplifier performance. In effect, the HT-S990THX represents a high-performance, powerful multichannel solution that combines the convenience of all-in-one systems with the performance of much higher priced separate components. With full THX processing capabilities—THX ASA-derived playback modes (THX Cinema2, THX Music Mode, THX Games Mode)—you can be assured that this system brings out the full potential of surround sound for all entertainment options. Equally as important, Onkyo’s Wide Range Amplifier Technology (WRAT) gives the system a perfect base for stellar amplifier performance. Also, the HT-S990THX’s compatibility with XM Satellite Radio® and the iPod® offers a completeness to this home entertainment system that has rarely been seen before.
