I have to agree 100% with banders@smart.com I bought a pair of the Klipsch KLF-20's brand new and went through replacing the tweeters and the mid horn with titanium versions and it was just way to bright for my wife and I. This was also done at the same time having the cross overs upgraded and yes the cross overs were the right kind and the most expensive ones to buy. I experienced a similar sound that banders@smart.com went through and my wife and I just did not like what we heard. We also invited friends over and had them bring their own music in order to hear the speakers with all the upgrades and before we made the speakers back to the way they were. All agreed that the 20's sounded much better and a lot smoother and less harsh sounding with their original diaphragms put back in. My 20's are still in my living room after 15 years and sounding just like day one hooked up to a Meridian G57 Power Amp, Classe CP-47.5 pre amp, Onkyo T-4711 Tuner and a Denon DCD-3000 CD Player, and Audioquest wires. You should hear Frank Sinatra voice coming out of those Mid-Range horns, wonderful, just wonderful. banders@smart.com, I have to say you really do know what you are talking about when you say along the lines of using higher quality electronics for the better sound. I would put my 20's with their original diaphragms against anybody's horn speaker with titanium diaphragms anyday.
