Those compressed air SSSSSCAT can's work great, and double as great fun to use on family members and coworkers. I purchased two of them when I first got my drum kit and was paranoid about the cats scratching up the drum heads. They went near my kit maybe twice at most... Set em up on book cases or around corners to use on family and friends []

I ran the Anthem ARC this afternoon just so that I could see where the Heresy's are at after the upgrade. The software sweeps the entire room to evaluate the effect of the rooms characteristics on the test signal. The below graphs are the result of six test sweeps per speaker measured at 6 different positions in the room. The dotted BLUE line is the target and the RED line is the actual measured signal as effected by the room. It's a fair grafical reference as to what one might expect to see by upgrading the caps on the crossover, changing the gasket in the midrange horn, and resealing the back cover of the speakers. While changes are subtle...they're measurable.I think these graphs support changing the tweeters to Crites CW-125's

They sound great! Well worth the $75 for everything shipped. I can run another room sweep to show before and after measurements, just for curiosity sake. Maybe tomorrow since it's going to be raining in the afternoon.

Performed a successful routine surgery on the Heresy's today. Updated caps, new midrange horn gaskets, gasketed the entire inside lip on the backs of both speakers and installed the slanted risers. I was impatient and installed the risers unstained. Looks aweful...but I'll stain em when I have the materials on hand. I'm more comfortable with saying good bye to the klf-20's whenever the opportunity presents itself. []

Thoughts on bi-wiring these Heresy's? I know that it's an option with the new III's. Pros/Cons?

Spoke to Bob Crites for a little bit yesterday, just so that I could put together a shopping list for what I may want to do gpoing forward. I opened up the back of both cabinets, to familiarize myself.Type E crossover. No surpprise there. I'll probably to the rebuild myself. Both speakers have soldered K-55-V midrange drivers. I'm pretty happy about that. So far I'm planning on getting a roll of 1/8 x" 1/2" speaker sealing tape (It's non existent on the cabinets right now), Crossover Repair Kit and the Heresy Slant Risers. Still need to test the tweeter. What I'd like to know, is if any members have purchased aftermarket speaker spikes. If so, how easy are they to install? Thanks...Walt

Heresy's are in the living room and the next step was to run the Anthem ARC for the new speaker configuration. Below is the measured frequency responce of the Heresy's as effected by the dimensions and furniture in the room.The most recent measurements for the klf-20's are shown at the bottom of the picture below. Interesting that the bass coming out of the Right Front is significantly higher than the Left Front. The speaker if firing directly into a 5" high carpeted isolation deck that I keep my drum kit on.It's about 2' back from the deck. Looking at the klf's graph...there's no difference due to the increased height of the woofers. Pretty cool to see it actually measured like this. Due to the size of the klf's I'm most likely not going to try and A/B the two pairs of speakers. I'll use the information shown below as the reference. I'm hoping that somebody more knowledgable than myself might be able to interpret the measurements and suggest what I may want to address as far as component changes for the Heresy's. IE: complete crossovers vs caps...etc Thanks...Walt []

So would this be pertinent? K-53-K, K-52-K, K-52H, K-57-K, K-58-K, K-59-K, K-61-K, and K-62-K. Beginning in the early to mid 1980s, we see a different type of midrange driver from those above used in some Klipsch speakers. This driver is derived from a Heppner driver and adapted by Klipsch. Early versions of this driver had the phase plug as a separate metal piece that was in front of a plastic piece holding the diaphragm. This type also had a threaded metal "nose" that allowed it to be screwed onto a horn.

Thanks for all of the input so far. I've been a lurker in the community since around 1999 when I picked up my klf's. I've already pretty much made up my mind that the Heresy's are going to replace the klf's in the living room. I lost a pair of Heresy II's back around 1995 and I have fond memories of them. I'm in a 16 x 14 living room right now...but antisipate moving into a smaller place in the not too, too distant future.The klfs just take up too much real estate to shine. I guess I'll just keep this thread going, since this is going to be a "potential Heresy project"...because I don't know how far I'll go with making changes to these HOL's. I'm a big traditionalist and I couldn't be happier with finding a pair of 1981 build Heresy's. But the klf-20's will go back in the boxes, since there's no way I can use them in the gym. They'll go up for sale to fund whatever upgrades I want to do to the Heresy's. I don't want to hi jack my own thread and turn it into a sale thread. But...these klf-20's were THE pair used at the Tweeter Etc head quarters in Cranston, MA for training. They're currently connected to an Anthem MRX 500 receiver with 12' Bi-wired MIT Terminator 2 cables...which obsolutely transformed these towers from screamers into something warm and powerful. Like I said...they just require more real estate than I'm going to have to work with. Unfortunately...I need to wait until tomorrow to start the swap. Please keep the ideas coming. I definitely need some guidance with the Heresy's. []

Well I've got these home and hooked up to the Denon 3300 in the gym for the moment. Condition wise...these far surpassed what I thought I was getting into. They're HOL build, and the cabinets can stand on their own just as they are right now. The grills are pretty near perfect, sept for maybe one slight pull in the fabric. I got to listen to some half speed mastered vinyl while I was still at the owners home, and my heart almost broke that I was taking these from them. I heard warmth out of these speakers that I've never gotten from the klf-20's.I'm actually already considering the Heresy's going into the livingroom in place of the klf's. I've got a Velodyne HGS-12 that is more than capable of taking care of any loss of bass between the klf to the Heresy. I'm just going to relax for a few days and get used to hearing the different nuanses of the two pairs. I'm in no real hurry. The Heresys sound great just the way they are. But I'll check out Bob Crites site to price up new caps. How would I go about testing the tweeter to check if it's blown?

I'm picking up a pair of 1982 Heresy's tomorrow and I wanted to ask the community if there are any potential issues that I should look into once I get these home. I originally thought these were II's...but a quick browse through the interweb seems to peg this manufacture date to the original Heresy. I'll know more once they're home. I'll take some pics and "maybe" open them up to see how the crossovers and cones look. Seems I'm going to have an abundance (well, abundance for me) of audio gear around me after picking these up. I'm going to need to A/B these with my klf-20's to decide what I want to keep in the living room. I recently picked up a new Anthem MRX 500 receiver, but kept my Denon AVR 3300...so I'll have some decent audio to hook up to whichever pair of speakers find their way into my gym.Then there's the Ohm's and Polk's...lol
