Good day sir back in 1976 Klipsch Pro was a big thing in the New Orleans area a Salesman came to a distributor of Klipsch in Gretna and played an album that had a flute Concerto in it that produced enough sound pressure that actually cause you to fall to your knees because of equilibrium,, pressure. My question is is there anybody left from back in the days can tell me what the name of that album was they were ran through a pair of LSi with a crown DC amp I've searched around and I cannot find it thank you for any input you can give me on this Sent from my SM-G900T using Tapatalk
