wlg235 Posted April 22, 2011 Share Posted April 22, 2011 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 Quote Link to comment Share on other sites More sharing options...
Guest " " Posted April 22, 2011 Share Posted April 22, 2011 blown tweeters. you need to listen real close to the tweeter with a rolled up magazine yo really get a sense if it is blown or not. Quote Link to comment Share on other sites More sharing options...
chisoxpurdue Posted April 23, 2011 Share Posted April 23, 2011 Yes the tweeters are what would most likely be blown. The caps will need to be refreshed. I would love to hear about the A/B with klf-20's. Quote Link to comment Share on other sites More sharing options...
wlg235 Posted April 23, 2011 Author Share Posted April 23, 2011 Well I've got these home and hooked up to the Denon 3300 inthe gym for the moment. Condition wise...these far surpassed what I thought Iwas getting into. They're HOL build, and the cabinets can stand on their ownjust as they are right now. The grills are pretty near perfect, sept for maybeone 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? Quote Link to comment Share on other sites More sharing options...
chisoxpurdue Posted April 23, 2011 Share Posted April 23, 2011 Two ways to test the tweeter horns. The way I test them is I roll up a towel and place it in the mid-range horn. Then I can hear if the highs are coming from the tweeter or not. Other people listen for it differently. I am sure they will pass along their info. No matter if they or blown or not, crites titanium diaphragms would be an improvement at a later date. Just a helpful tip for later. Quote Link to comment Share on other sites More sharing options...

Groomlakearea51 Posted April 24, 2011 Share Posted April 24, 2011 Caps, replace midrange driver gasket, and make absolutely sure that the back is sealed. Over time it gets "leaky". Use speaker 1/8" thick gasket tape from parts express. There is alot of things that can be done with the Heresy's ranging from a simple caps change all the way up to replacing the woofer with the K-28 (H-III), new K55's (Atlas PD5VH's), different crossover configuration (e.g. E/4500) and using the CT 125 tweeters.

wlg235 Posted April 24, 2011 Author Share Posted April 24, 2011 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. [] Quote Link to comment Share on other sites More sharing options...

wlg235 Posted April 24, 2011 Author Share Posted April 24, 2011 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. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted April 25, 2011 Share Posted April 25, 2011 Correct; in mid-late 1983, the K-53/701 combination was substituted for the original K55/700 midrange. See: http://forums.klipsch.com/forums/t/103886.aspx Quote Link to comment Share on other sites More sharing options...
wlg235 Posted April 25, 2011 Author Share Posted April 25, 2011 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 [] Quote Link to comment Share on other sites More sharing options...
wlg235 Posted April 26, 2011 Author Share Posted April 26, 2011 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 Quote Link to comment Share on other sites More sharing options...
wlg235 Posted May 1, 2011 Author Share Posted May 1, 2011 Thoughts on bi-wiring these Heresy's? I know that it's an option with the new III's. Pros/Cons? Quote Link to comment Share on other sites More sharing options...
wlg235 Posted May 3, 2011 Author Share Posted May 3, 2011 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.

Rusty Melton Posted May 3, 2011 Share Posted May 3, 2011 How does it sound, was it worth the effort? I just bought a set of them and have been thinking of doing the same thing. Quote Link to comment Share on other sites More sharing options...
wlg235 Posted May 3, 2011 Author Share Posted May 3, 2011 How does it sound, was it worth the upgrades? I just bought a set of them and have been thinking of doing the same thing. 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.

wlg235 Posted May 4, 2011 Author Share Posted May 4, 2011 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 Quote Link to comment Share on other sites More sharing options...
