Hello,
I recently purchased the full 7.2 system. It sounds great, and I am mostly happy. But, like others have mentioned the subwoofers barely put out any bass at all. I have played with the position, distance, and level settings. It's pretty pathetic I have two subwoofers that should bring down the house and they barely make a sound. Also, while playing music only one subwoofer actually makes sound, the other is barely moving the cone. I verified both subs work by turning them off one at a time and playing music through them as a 7.1 system.
The next problem is that the surround DSP modes seem to do absolutely nothing. I can send a full 7.1 PCM signal at the control center and get great sound out of all my speakers. But while playing 2.0 PCM music through Bluetooth, I select all channel stereo surround mode and still only hear music through my two front speakers. Also, none of the dolby or DTS surround modes do anything with a 2.0 signal. Only sound out of the two fronts.
