Any good recommendations? I'll probably buy off of eBay to save some cash.. thinking of mbQ, diamond, or Boston Acoustics... any other recommendations? Must be very crisp, clear, and accurate.

I have Infinity presently with JL SE40T tweeters..infinity is stock, but its gold series running off of stock 180w 4-channel amp. Will be replaced by MTX Blue Thunder 4-channel amp. Sounds OK presently, but bass really drowns out the highs when I crank it.

EDIT: And does anyone make a component 6x9 set? Or is it basically only available in the 2-way, 3-way, 4-way, etc..?
