I'm looking for a solid 2.1 system for my TV, ideally under $700. My requirements being that the system turns off and on automatically with the TV, the ability to control the system's volume with the TV's remote, and a wireless sub. I've listened to a few sound bars, but all of them sucked so I've come to the conclusion that the best 2.1 system will be one with separate, individual speakers. The only system I've been able to find to meet these requirements is the Onkyo LS3100. Is there anything else out there?
