I built 4Pi's with the Eminence drivers- Omega and PSD 2002 and was very happy with them. Very good bang for the buck and everyone who heard them liked them. I later upgraded the comp driver to the B&C DE250 and only did 1 side at first. The improvement was very noticeable to everyone who listened, and I later got some JBL 2226's, and again, the difference was well worth the extra bucks. So, get whatever you can afford- they are all worth the money you pay & give good value at the different price breaks.
