  1. Hello all, EDIT: Also, I found that using two amplifiers and bi-amping the tweeters and woofers to separate amps allows for better control on the harshness of the tweeters! Also, if you have vacuum tube amplifiers, I heard that vacuum tubes are less harsh and are less anxiety-inducing than solid-state! I wanted to make a post to address an issue I have been "tolerating" for about a year now with my Klipsch RF-62IIIs which is the harshness coming from the Tractrix horns — harshness on high frequencies (around 2.5khz to 5khz) which I can feel hurting my ears which leaves my ears physically sore for a few hours after I stop listening to music. I found a YouTube video where someone adhered automotive sound dampening foam to the outside of the horn on the inside of the speaker cabinet, after following the video, I noticed an improvement in the harshness, but I still had the problem. I decided to put foam on the inside of the horn and noticed an improvement again. I have added three layers of foam to the inside of the horn and one layer on the outside. I also recommend adding foam to the throat of the horn to fill in the gap (without covering the driver) between the throat and the line that can be drawn from the base of the driver out toward the listener for further acoustic dampening. Klipsch is aware of this problem with the horn harshness as you can see the newer speaker models have a silicone dampening material inside the horn, but I recommend Klipsch sells a better engineered version of my solution in varying degrees of dampening or opt to design a speaker without a horn for once because I plan on selling my speakers and getting speakers without horns because I value my hearing and cannot continue to tolerate the ear pain. Here is my design using the automotive sound dampening foam if anyone wants to try my modification: https://drive.google.com/file/d/1NXgl6Dhet2LYhwqq3Pf3OWMHwco11R5a/view?usp=sharing Hope I save someone else from hearing damage!

  2. Greetings, Long time Klipsch owner but new to forum.. just picked up a very lovely sounding RC-7, not sure why I waited so long., now being used as my center channel. Since Crites passed recently,, my condolences to his family and friends, .. and it looks like DeanG is retired from retirement,, who is reputable to take on a crossover rebuild/refresh? While my new used speaker is working as expected, it is original and stock so I am sure at a minimum the caps need updating.. after 12-15 years, maybe more? Thanks, Mike
  3. I have decided to embark on a Heresy Restoration/Rebuild project, estimated cost to be ~$1500 I found a pair of Heresy I cabinets on e-bay, the condition and the finish looks good. Crites has all the needed drivers and X-Overs, along with the risers. I used Crites for my Forte II (1989) modifications (X-over and tweeter diaphragms) and was very pleased with the results. Is there anything else to consider? Do I need to seal the cabinet seams?
  4. Calling all Bill Fitzmaurice fans! There is a table tuba that someone is offering me that has an unusual modification. The builder set an extra inch of room for the woofer driver than what was written in the plans and, as a result, the horn has an extra 6 inches of length I believe. I'm wondering how this will affect the frequencies and if it renders the subwoofer useless. The builder claims that he cannot tell any difference--but wanted me to know for the sake of transparency and specifically pointed me to you all. Any advice is appreciated! Thanks all!
