I love the Klipsch KLF series. I've wanted to acquire a pair and modify them with new baltic birch cabinets. In December, I found a pair of KLF-20's that were the perfect candidates. New 1" thick baltic birch top, bottom and side panels were constructed. The crossovers were re-capped with Dayton Audio 1% precision poly caps. The tweeters were upgraded to Bob Crites Titanium.
