That was one heck of a speaker! Good luck finding one.
WANTED - Infinity Quantum Line Soure One, QLS1, Q1's
I have wanted a pair of these for 40 years. I helped my best friend get a beautiful pair out of California. If anyone has these speakers, and wants to sell, please contact me. Walnut or Rosewood both work. Obviously I am looking for a nice air with all working original driver. Thanks.
