My point: If you're finishing out the back, you're not using tem as corner horns, but as free-standing speakers. The bass response is now kaput, so you get a sub-woofer. You've ruined the speaker's design (I know some like it that way, but some people never exceed 50 mph in a Porsche, either, and are perfectly happy).
Perhaps I should have titled the post, "How to convert Klipschorns into Belles".
