Upscale Audio is closing out the Triangle Heliade @ $700/pr new. This is a little over your stated limit, but the speaker was competitive at its list price of $1400/pr, so it's worth at least thinking about. It's a good looking, good sounding, easy to drive tower speaker with a smallish footprint. The only real downside in that response below app 40hz is MIA.
Good Luck
