I was wondering if anyone else has used Hi-Vi drivers in their DIY projects. I have a pair of F6's and a pair or RT2's in my speakers. What have you done with them? And what kind of X-over did you use? If you have no idea what i'm talking about, go on over to http://www.dulcet.com to check them out. One look at the response curves (more like straight lines!) and you'll see how awsome these are.
