RF-7 fan

An audiophile buddy of mine and I performed this mod on his RF-7 Klipsch horns and it made a huge improvement in the overall sound. The high frequencies were just as detailed but it removed all of the fatiguing harshness, especially when listening to female vocals, violins or anything in the upper register. Tried the spray material, but it didn’t do much. We then switched to a Bitumex-like tape, and that did the trick. He was connecting these speakers to some high end McIntosh amps and even when played at moderate volume levels, the overall sonic improvements were instantly noticeable. Klipsch must have recognized this design flaw because they now use some type of rubber composite material in their latest RF-7 III horns. Don’t think twice about it, definitely do this inexpensive mod! Regardless of the musical genres that you listen to, you’ll be extremely pleased with the results.
