Forgive me if this question has already been asked, but I didn't see it here anyplace. Does anybody know of some halfway decent 6" speakers that can be bought off the shelf that would fit into a D8443 without having to make any modifications to the box itself? I know they would have to be pretty slim and I'm not changing/adding amps, so they would also need to be something that's pretty easily driven. I would greatly appreciate any pointers that anybody might have.
