MickShrimpton Posted August 17, 2021 Share Posted August 17, 2021 (edited) Hi Everyone - I'm new here to this forum but not to the Klipsch line of loudspeakers. Maybe I will do a separate intro post and list off my collection. Onto the reason for this thread. My newest acquisition is a set of 1966 H700's. They were bundled by the seller with a mismatched set of Heresy I's. I originally went to go look at the Heresy's and while I was there he asked if I wanted to see one more set, and like any one of us would say I said "definitely". Once I saw these beauties I knew I had to have them, I asked what he wanted for them and he said if I took the other set he would thrown these in for and extra $100. SOLD One speaker is in amazing shape and the other is meh. The one looks like it has possible water damage judging by the seeming water mark and staining on the front cloth. Luckily that looks like the extent of the damage as the woofer and crossover have no visible signs of damage or corrosion. I hooked these up and they sounded terrible, I immediately knew something was up. When I opened them up, I immediately knew why they sounded like crap. Why someone would do this to these speakers baffles me... 😢 they took out the tweeters and mids and replaced them with some cheap no name paper cone junk. The replacements weren't even in line with the cutouts. And while they were at it they hot glued everything in place and made a mess. The pics will better explain. I am just happy the EV K-22's were left untouched and look to be in amazing shape. They sure are some beautiful looking woofers!!! That being said these guys are screaming for a rebuild to bring them back to their original glory. From what I could find online these should have came with K-77 tweeters and K-55V mids w/ K700 horns. **I do have wanted ads in the Garage Sale section for each if anyone has some for sale.** I figure this thread will give a story as to why I am searching for these. I have reached out to Crites and have been messaging with Michael about my options should I choose to go with Crites. I am thinking I want to stay with the K-55-V / Atlas PD-5VH for the mids and go with the Crites CT125 tweeters for the improved higher end response. Crossovers are another story. The stamp on the crossover plate looks like it says 4RC. I cannot seem to find anything online about this H700 crossover. Would this be considered a Type C?? If anyone with more info on these can chime in please do. Michael over at Crites is looking into these but I haven't heard anything back yet on this type of crossover. Anyway, that's the story with these, and be forewarned this will be a slow moving rebuild but I will keep this thread up to date with progress to hopefully help out others should they choose to do the same. Thanks for taking the time to read this novel of a post! 😃 Edited August 17, 2021 by MickShrimpton Corrected year from 1965 to 1966 in subject and body.

MickShrimpton Posted August 17, 2021 Author Share Posted August 17, 2021 Water damage. If anyone has the best method to clean the cabinet up and get the staining out of the cloth please let me know. I would like to keep the original cloth and not change it. Would just some wood restorer clean up that water line? 1 Quote Link to comment Share on other sites More sharing options...

Part of me wants to just get these going as fast as I can and enjoy them. I did find some square driver K77's here in the garage sale forum that I might buy just to get them going. But I do understand keeping these authentic, they might sit longer going that route... and having a pair of Klipsch sitting dormant has been driving me nuts 😅 Quote Link to comment Share on other sites More sharing options...

MickShrimpton Posted August 24, 2021 Author Share Posted August 24, 2021 Thanks to some awesome members on this forum I was able to source a pair of K77 tweeters and a pair of K-53-K mids to get these things going. Thanks @RickD and @justonemore! I also bought some K700 cast horns for when I eventually find some K-55 drivers to do these things right and keep their original character. Will update once I get these drivers in. Hoping the crossovers have held up over the years. Actually has anyone heard of the "4RC" crossovers that are in here? Are these considered Type C crossovers? I heard back from Michael at Crites and he stated he hadn't had any experience with this type of crossover and for me to just buy some new Type E's. I would rather keep these and rebuild if needed. Problem is I can't find anything about them. Pics can be seen above on my post #4. 1 Quote Link to comment Share on other sites More sharing options...
AndreG. Posted August 24, 2021 Share Posted August 24, 2021 I´m being a bit silly now; everytime i read stories about one of you guys finding some old Klipsch speakers and fixing them up, i get a bit jealous. Sometimes i wish it were so easy to find some here in Germany. Here, if older stuff turns up and even if it´s almost junk, people still demand ridiculous sums for them. But it´s always interesting and fun to read and gives me ideas. 1 Quote Link to comment Share on other sites More sharing options...

But it´s always interesting and fun to read and gives me ideas. They are definitely hard to come by in my area as well. Just happened to be in the right place at the right time for these. Seems it was meant to be in this case and ended up making a friend with the guy that sold these to me. I love this hobby and the connections you make sometimes are even better than the gear involved. Hang in there Andre, something will eventually come your way. Quote Link to comment Share on other sites More sharing options...
MickShrimpton Posted August 30, 2021 Author Share Posted August 30, 2021 Update 8.30.2021 Got some parts in the mail last week and had the time to install the tweeters and mid squawkers. I did have to modify the mid K701 horns a tad to make them fit in the H700 setup. What I did was use a K700 horn as a template and Dremel out a piece of the flange. Pic attached for reference. This allowed it to clear the K77 tweeter flange. Fit like a glove. I also removed the original fabric and plan on cleaning it before re attaching to the motor board. I have also been pondering the idea of having some replacement grill covers made and attaching the original cloth to those so they can be removable. These H700's look amazing with the covers on as well as off, those K22 EV woofers are so pretty. For the meantime I am going to run them as is without covers. After the drivers were installed. I buttoned everything up. Now mind you I did not seal the cabinets or drivers. I put them back together as they would have come from the factory and boy they sound sooooooo flat. No bass whatsoever and they don't have that soundstage that my other pair of Heresy I's have. That's my comparison by the way, It's night and day. I am chalking that up to the crossovers needing a recap and the cabinet not being sealed up. I have a PE order in for some gasketing foam and caulk, new Solen 2uF caps and screws. I am hoping after all of that these things come to life. If anyone has other suggestions on how to improve the sounds please let me know. Stay tuned. 1 Quote Link to comment Share on other sites More sharing options...

AndreG. Posted August 30, 2021 Share Posted August 30, 2021 Looking good so far. With those woofers i´d really opt to go without grilles ( says the guy who usually doesn´t like his speakers sans grilles.). Hope You can get the sonic problem fixed... 1 Quote Link to comment Share on other sites More sharing options...
