Model number is ht-s7300. It comes with all 2 large front speaker, center, 4 surrounds and a subwoofer for full 7.1 The subwoofer still works, but is starting to show its age. The cat got ahold of it and put a couple tiny holes on it. I repaired it with rtv silicone. Loud bass heavy music sounds great, but for some reason the loud explosions on movies can be off at very high volumes. The original remote is included, but the volume up button does not work. The audessy tuning mic is also included. It's 1200W, hdmi 1.4 with 4 inputs, full HD 1080p, decodes dolby true HD and dts HD. If you have a 4k tv, you can still use an optical cable to hook it up. Let me know if you have any questions
