Deang, thank you. I found your great tutorial here “building the type AA”. It saved me huge amount of time. Second crossover installed today and finally I have parsel with tube amp. Next few days I am going to enjoy the music.

New crossover has been built with the same nominal of all parts as original one. Already installed into one speaker. The most significant changes in sound in mid range, especially vocal. When two speakers play together old one takes all attention, like it sounds louder. But new one plays definitely cleaner, the best word is - less colorization. My first impression - new parts in crossover make sound more balanced. I was looking for more highs in a beginning, but now I have a feeling that mid was playing to bright and took all attention. I will finish second crossover soon and will see how stereo going to play.

Almost 100% found an issue. I did replace two blue capacitors 1.5uF on a one speaker in a tweeter path. Yes! Huge diffenent if comparing to another side. I had only pair of Mkp Audiophiler 2.2 uF ordered from China. Bells came back! Just in case ESR meter reads 0.5 Om for old stock capacitor and 0.1 Om for new one. Now I know where to move - rebuild crossovers.

Tube from a paper towel holder did the job! Tweeters are not dead. Thank you for your advises. My setup is probably too weak to reproduce all frequencies diapason. I am going to work in this direction also will move crossovers on a separate board and recap capacitors. The more I listen Heresy, the more I like it.

Hello, I am new on a Klipsch forum and never heard any klipsch speakers before. But as a try I purchased pair of old Heresy II. Cosmetically not perfect, but drivers sims to me are working. Cabinets have round cup terminal on a back. Crossover looks very simple. My first impression with a sound - WOW! Very dynamically! I would definitely like to restore them to original specs or do minor improvements where it is possible. I`ve read that there are some mods possible - Ti diaphragms on Mids and Hights, crossover mods... Currently I am using simple yamaha receiver. Waiting for Yaqin MS-13s tube amplifier from Hong Kong. Hopefully will have it before summer. Lol. What I would like to improve - lack of high frequencies. H2 sounds very dynamic in a middle, but there is no highs. Custom build speakers (Scan-Speak D6600 tweeter + Focal 165W mid) with the same receiver sounds much higher. I am not sure if tweeters are working properly, I mean there is some sort of sound came from tweets, but very week level. If someone in Chicago area (north suburbs) can help me evaluate my speakers and tell if they are OK? it will be awesome. I am afraid of doing any modification before find out what is wrong. Could you also recommend me "must to do" list if it exist: Just for example: - replace capacitors in crossover, - move crossover to separate board, - Ti tweeters diaphragm ... Thanks, Elisei
