Here's an idea, but they're well below your budget. Silverline Prelude. They go only down to 35Hz, but you'll likely not miss the lowest bass unless you're a metal head (like me). I'm a bass hound, and I was darned impressed by these at CES. 91dB/8 ohm nominal...they can be driven by a wide variety of amps including relatively low powered tube amps (I'd guess 30+ wpc).
They cost $1200 new, and can often be found for ~$800 used. Heck, at that price, buy a used pair and try them out. If they don't work for you, then re-sell.
