Look at EMP, HTD, Arx, Aperion, Ascend, HSU, DIY..if that's your thing....can't think of any others right now. Oh, the Focal 814v from A4L is a good buy in this range also. There's plenty of reviews out there for the EMP's, Aperions and HTD's. I say this like always....you can't beat EMP and Aperions 30-day trial if you can't audition. It's a nice thing to have before buying, realizing you don't like them (aka...same boat you're in now) and having to sell them or return them for a small loss.
