big sound at a down to earth price?

Hi,

I visited my local high-end store and end up listening to the large Snells. I walked away impressed with the very BIG sound they threw. While, I could never afford to buy the Snells, I wonder what other speakers out there that can produce a big sound at a real world price (used under 1.5K)? I do have a big room to accomadate larger speakers.

Thank,

Rich
