I just finished building a set of these...
http://www.diysoundgroup.com/coaxial-speaker-kits/volt-10lxe.htmlThey blew me away. I purchased them with the ported flat pack to use as surround speakers. Now that I finished them and took a listen, I am dumping my Klipsch speakers and going with more of these. They are some of the best speakers I have ever heard, and I think they are pretty cheap as well. They are also some of the loudest home speakers I have ever heard.
