yep, I've been reading up on ARC2 sounds cool. I like the option of doing quick measurements of speakers or subs to get things set before running the process. According to Audioholics article it works great with multiple subs. I just wish there were more people selling that brand to bring prices down. There is one Ebay seller, but that is a bit scarry for warranty issues even though they offer a 5 year squaretrade warranty. I would also have to figure out what to do with my current speaker positions/wiring. My side Q's are mounted higher up and angled down. The rears are a bit lower right behind the back row. I do have a pair of onwall 22's as well as regular 22's in boxes, hmmm
