I have another thread for my HT, but I figured these were two very different topics. As part of our attic renovation and theater build we are also adding a bedroom and full bath. In the bath we are doing a steam shower. I use Sonos for whole home audio and would and have an extra ZP100 that would power a set of speakers...question is, what speakers do I get? I was wondering about marine speakers that Polk makes for boating. They need to be vapor proof and pretty much splash proof. They are not for critical listening, but would like them to sound decent. Any ideas? The cavity in the wall will probably only accomodate a pair od 6.5s...maybe could get some 8 inch, but it would be tight between the joists. Any recommendations?
