so, those have the KLH mids/highs? not the janszen 130U?

and has absolutely no problems. This is my 17th year; there is no question as to my status. I've seen them come in totally paralyzed, and walk out. Sometimes it takes years; keep up the physical therapy they say. You didn't say how long since your accident. Good luck to you, I hope you have access to good help. :thmbsp:
Brian, I don't know how a guy would do this without destroying the cabinets; there are no screws, they are glued and completely sealed. The drivers may be removable, but the grills aren't. There is a bit of resonation that bracing may reduce... but that might be my ears or the amps or WKW. Surely the x-overs need help but..... :scratch2:Brian said:I suspect the bass module could stand some bracing and the x-over some new caps to get them up and running right.
I hear you Brian. The low-efficiency design of these and working the amps at 16Ω makes the large and sensitive meters show the jumps to high levels very quickly, even at low volumes. The needles bounce from 20-70W at one setting; 50-110W further up the scale; max w/o clipping is pinned from 90-redline. I only went about half-volume, and it didn't max the speakers out, but don't have reason to drive them that hard again.Brian said:Congrats on getting them. Be careful as to the power. Remember these were designed LONG before high powered amps were out and for a community that primarily listened to classical, chamber and vocals at polite levels so easy to burn out the drivers. Also, they are old and age should be respected.
It is probably fortunate for them that my hands don't work. Before I broke my neck, I worked on an early model KLH that was glued together. The back didn't come off, and the woofer wasn't very cooperative.Brian said:As for getting to the x-over; its been so many years since I had my hands on a set of these I am not sure how to get into them. 1st look closely around the perimeter of the grill and see if either tacks or staples can be seen. The were made in a period when many grills were inserted into the cabinet and then the baffle so the box has to be opened to get the grill out. So they could be either tacked on or not removable externally. I think some of the early KLH 6 owners can advise as to hoow to get to the x-over when you can not remove the woofer (for whatever reason) as the woofer on the early 6 is bonded to the baffle.
I don't hear any flaws, so will keep them as-is, listened to through sheets, in my living room. I live alone and actually spend little time there now. Thanks for the background info... any more, sites etc.? I have found little on these.Brian said:Good luck with then and thank you for saving a truly great piece of audio history. These preceded Art's hybrids AFAIK and were specifically made to accept his array. The AR1w was not designed with his array as a design criteria so hence, I think the KLH 1 with the JansZen may have been the first designed as such hybrid dynamic woofer / electrostatic stereo speaker. The fact that you have the even more rare 5 addon system make you set even more exclusive and interesting.
prior to my discharge from the Army. Working on tank engines for them 13 years had its affects, especially the later gas turbine M1.I got it, Brian, with a little research. I see some JansZens on eBay... they sure are expensive! Might be in the best way for me to get into electrostatics though. I wonder how well they survive and how to fix them.Brian said:The sound of the 2 modules whould be different but that is not the fault of KLH design.
