9.7.2021 Update Over the holiday weekend I made some progress. Installed the new Solen 2.0 uF caps. Wired the Type C crossover to the Type E. Sealed the front motor board, rear panel and all drivers with foam gasketing tape. Lined and stuffed the cabinet with batts of wool insulation. Sound quality has now improved substantially! Most notably is the low end, it is tight and accurate. In comparing these H700's to my other pair of Heresy's these now seem to dig a bit deeper in the bass department. The other huge takeaway is that the sound transparency is back, no longer do I feel the speakers are shouting at me from their locations. As the caps are breaking in the sound keeps getting better and the soundstage wider. Overall I am more than happy with the results. Next step will be the cosmetic process but I'm in no rush to get that complete. For now I'll keep listening to these and enjoying them.

Agreed, that's why I want to try and get some removable ones made up. Best of both worlds.

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.

I have had these Heresy I's for a few weeks now and I think they will do the job for a while... La Scalas are always on the radar but I actually would like some Chorus II's if those ever pop up locally.

Had to Google MWM... Ummm I may need to buy an outdoor venue and win the lottery hahaha

Exactly! And I still use those 1.5's daily.

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.

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.

I second this. Have used it for years. Simple interface and it works great! Even with some of my scratched CD's it managed to rip them without any evidence of the scratches. Good luck!

Thanks Shakey. Definitely seems like a great bunch! Glad you made it back to Klipsch!

Thanks for that, I corrected the subject to 1966. This is something I have debated in my head since getting these. 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 😅

Hahaha they sure are, great way to put it.

Great stuff in there, much appreciated! The crossover section of that doc makes me think I might have a Type C...
