as of now the only components I have are the k77s. I'm looking to build 4 way speakers. Woofers will be peavey black widow 1502s, upper mid will be jbl 2105h, and tweets will be the k77. I'm looking for a low mid speaker, so if anyone has any suggestions, i'm open to them. I have no idea what I'll be doing with the box as of yet, I've ordered some books and I'm waiting for them to arrive. I've also got a set of jbl 2441h's that I'll be building a subwoofer or 2 with. I'm figuring on powering them with velodyne spl series amps that i've picked up on ebay. I had originally considered the idea of putting the amped 2241s in the speaker, but since they'll have to be in a portion of the box all to themselves, I think it will make the boxes inordinately big. I've really got no timeframe on this, I'm doing it more for a fun long term project and learning experience than anything, so I'm quite open to any suggestions or information. I'd like to put a website, but I'm sure it will be a few weeks till I get around to designing something.
