Karen's got the right idea with the Xtants, you may also want to check out the Soundstream Tarantulas or the aluminum Eclipse 10s...I don't really like any of the Kicker/JL/Sony stuff, if you're gonna buy a sub, buy a GREAT sub and keep it forever
Karen: You're running Boston Acoustics? Excellent choice!
The 6.5 pros? I was checking those out too, but they aren't as easy to find as other brands. Originally I had my heart set on the 6.5 HCCAs, but they were backordered
I eventually decided on the Focal 165K2s
