You should consider getting the DV64's directly from Ed Frias. Ed modifies the cross over, and driver matches the mid-woofers and tweeters. They aren't much more in cost.
From what I have read, they should not fail to impress for a budget speaker. Make sure you get a sub to handle the low end.
Check out the BIC H100 from the Acoustech line. Under $300 shipped with a 12" woofer and power handling that peaks at 500 watts. I have now personally evaluated this sub and WOW. I kills my PSB Alpha SubSonic1 10" sub, and the JBL 12" it replaced. Incredible bang for the buck.

I have attached his BIC Answers sheet. I will be getting two of the DV-62CLRS modded by him. I am going to do a before/after comparison.
