I've always bought pioneer 6.5 or 6x9 because their highs sound great. That's back when I have 2 p3 12" subs to back them up.
In the mirage, however, it's impractical to put a sub.
With that said, being an audiophile, I'd want y'alls opinions (preferably experiences) on speakers with best bass.
In fact, I might put pioneers up front (for highs) and whatever the best lows for the rear.
Go.
edit:
I'm looking at > 50RMS speakers. Planning on purchasing a 4ch 100rms per channel pioneer amp.
