Been using a Polk RM7200 system for several years now, powered by various Onkyo amps, and I know satellite systems are frowned upon by the bigger boys, I generally can't notice the sound difference unless I hear two systems side-by-side.
With that said, I've recently purchased a Denon 2312 receiver, and I'm going to be giving the RM7200 set to my brother, so I'm in the market for a new 5.1 setup. I'm trying to avoid floorstanding speakers since they're less portable, and my car isn't well suited to moving around floor standing speakers. I live in an apartment, so it's nice to be able to move easily. Some of the recommendations I've seen on this forum are::
Martin Logan MLT2
DefTech ProCinema 60.6
DefTech ProCinema 600 Refurb
Obviously, cheaper the better but if one is drastically better than the rest, then I wouldn't mind spending up to $500. My apartment is pretty small, room would probably be around 15'x15' , and probably a 50/50 mix of movies and music. I would rather not "downgrade" from the RM7200, but I know this is all subjective.
Also, there's someone on Craigslist down the road from me selling an older NIB Infinity TSS800 for ~$300.... not sure if that's a good deal or not.
I'm assuming that at this price range, they're all going to sound very similar? On paper, the DefTech's seem to have better frequency response than the other 3, with the satellites going well below 100Hz... although the midrange drivers on the MLT2 is an inch larger.. Any comments, suggestions, etc is appreciated.
