Powered subwoofer for Heritage series in Technical/Modifications Posted February 1, 2016 Everybody has some good comments. I actually have three LaScala's for my home theater (right, left, and center channels). I could have lived without the Klipschorn just fine, but got a nice deal on the empty cabinet. I want to somehow use it. The money I could get selling it does not matter to me. It might be better to use it in another room as a center channel carrying a mono signal for a stereo system that is strictly for music listening. I have such a room now, with all tube equipment. But it is a little cramped. This is probably a case of status or ego. There is just something about a Klipschorn, even if you have LaScala's. I could get another single one down the road. I would need to put them in another room to have the corners available. I will check out that link. Since I have subwoofers in my system, it sounds like adding a powered sub into the Klipschorn would be more trouble than it is worth.
