?Best speakers for a 2000 sq.ft loft?

anything really huge Pipedreams, Genesis 1's or similar, that's alot of air to be moving your going to need alot of power also suggest VTL Wotan 1200 amplifiers.

Your M-Ls should work fine as long as you sit in the near field. Place the speakers in the free field (a good thing) and seat yourself near a wall (for bass reinforcement). There's no need to pressurize the entire room.

the new b&w 800 seires will work well because they love an open area as such. Good Luck Gino

I saw an ad for the Genesis 201's here yesterday for less than half price. These are 4 towers w/multiple driver arrays. Two of the towers are bass/subwoofers, and the other two are tweeters and midrange. this is an incredibly good-sounding system, it blew me away, though I ended up with the Genesis 500's because I didn't have near enough room for the 201 system. If you've got $10,000, you should try to hear them.

If you want to stay with Martin Logan, a pair of Prodigy can fill up a 35'x60' room very nicely.
