No such thing as a Jube with a Peavey bass bottom. What makes a Jube (short for Jubilee) is THE bass HORN, not a k510 on top or K-402 (I have both) med tweeter part. I also have well as a second pair of modified Jube-clone bass bins with 3 K-31's inside, which I will, rightfully, call Super Jubes.
Roy himself admitted to making the "mistake" of naming a "Jube Scala" when he put a 510 on one LaScala bin, creating the mass confusion in the process.
Paul Klipsch is the one that came up with the name Jubilee primarily because it outperformed his original Klipschorn in measurement AND Listening (once he heard it, is whan he named it). 50 years after he designed his X2 prototype bass horn that became known as the Trademarked Klipschorn.
