Hallo
Maybe you will find this speaker too small, but it should have a good sound and "bottom" despite its small woofer.
I found them cheap (they were painted sliver) and last step is to provide them with oil and new suspension.
It is great too see other DIY projects, so here is mine. I dream one day to own a pair of L300 Summit.
More pictures to come.
Best Hi-Fi regards from Denmark.
