ShaughtUp Posted April 20, 2022 Share Posted April 20, 2022 Having inherited a pair of Klipsch Heresy speakers and having been told incorrectly it seems, that they were Heresy 2s,(the paper label had faded to illegibility) I took note of the kits available from Klipsch to upgrade to Heresy 3s. I sent in pics and serial #s, waited months for the kits to become available and purchased 2 for under 6 hundred bucks delivered. The instruction sheet mentioned an earlier model with a round input cap that this kit was imcompatible with, whereas I had no hole at all, just a terminal strip, and my original drivers were mounted from inside, an E2 crossover to the sidewall with the large silver oil capacitors. I now realize these are Heresy 1s even less compatible with this kit, but I made it work. The slots on my Heresys were narrow as they were not designed to pass drivers through the front, and the metal horns were narrower, with a thin flange compared to the new plastic horns, so the holes had to (gulp) be widened with a wood rasp including the woofer hole, and because the new wider tweeter driver had to pass through the front I had to cut a slot between the mid and tweeter holes, grind plastic off the bottom flange of the plastic tweeter horn right up to the mounting holes, and cut away a slot in the flange of the top of the midrange horn where they still overlapped. Finally I had to cut rectangular holes in the back panels with a drill, a forstner bit and a keyhole saw to accept the beautiful new crossovers. I sense you all shaking your heads and cringing out there, but the speakers sound AMAZING, transcendently beautiful clarity, the tendency towards glare on bright material is reduced, they are more dynamic, the bass goes a little lower and they play a little louder, SO worth the 3 days of cursing experimenting and worry! Klipschs are emotional laser beams with good single-ended amplification, they PLAY MUSIC! 4 Quote Link to comment Share on other sites More sharing options...

Marvel Posted April 21, 2022 Share Posted April 21, 2022 Don't know who told you what model you had. The original Heresy has a terminal strip and removable back. A cursory look around the forums would have told you that. Quote Link to comment Share on other sites More sharing options...

ShaughtUp Posted April 21, 2022 Author Share Posted April 21, 2022 True Marvel, was not a member here until I ran into difficulties with the install however- So after I cut the slot between the 2 horn holes on the baffle, the tweeter horn had to be carefully angled in, then moved into the midrange horn hole at one end, then the mid-horn/driver was squeezed through and moved to the other end of the midrange slot, the tweeter could then be slid up and into place. Once both horns were mounted a small piece of plywood cut to fit tightly in the slot was coated with shoe goo rubber cement and pushed into place from the inside, sealing the slot between the horns tightly. 2 Quote Link to comment Share on other sites More sharing options...
