@zinda, That's a long first post, welcome to the forum.
I think you are a little confused regarding crossover caps and ESR.
Hint: ESR is a non-issue for XO caps. We are talking audio frequencies here, not RF
How much of High End Audio is Horn Speakers?
An audio friend of mine had been discussing my future speaker purchase. We discussed, Harbeth, Devore, Spendor, Audio Note and other more traditional speaker brands. A week or two later he called an asked me what speakers I had purchased. When I told him Klipsch, there was a little silence on the other end of the line. Our call probably ended a little sooner then usual. I could tell he was disappointed in my purchase. Is it the Klipsch name that illicits this type of response or is it Horn speakers in general? After thinking about some of the other Audiophiles in town, a good deal of them are on the low power high efficiency speaker route and more than a few I know are using Horns. Does anyone know how the high end market share is divided? Is there a stigma associated with certain lower cost Horn speakers? Or is this just Klipsch? I now own a pair of Klipsch Cornwalls and am enjoying the journey associated with tweaking the sound to my taste. Is there an unwritten rule that friends don’t let friends buy Klipsch?
