I have a feeling that with anything less than horns, you're going to be disappointed.
Used set of Illusion Audio or Image Dynamics full or mini-bodies with a stout 7"/8" midbass would be my choice. Bi-amped, of course. You could run one of those Morel 3" VC beasts if you want something with high power handling, or a Peerless SLS...
For the amp, hard to beat the value of something used...you can pick up a PG M series 4-channel for peanuts, and I'd trust something like that before a low-level Hifonics.
