I just purchased a Theater Research TR-6010 system off of ebay for 75 dollars, shipping included. This system is said to contain a sub, 5 satellite speakers and a remote. I have read the posts about the scam going on about Theater Research systems and I was wondering, have I been duped? I just want to use this for my dorm room at college and at 75 dollars, i thought that was pretty good. What I need to know is, will I need a receiver to use this system? I need to know anything and everything anyone knows about this system, and if anyone has it, please post the sound quality. Thanks so much!!
