bullwinkle Posted March 23, 2006 Share Posted March 23, 2006 Just purchased a pair of Heresy speakers 1983, birch unfinished. Not here yet, but, I heard somewhere that it might be a good idea to update the crossovers. Also, I saw a pair that had mdf 3/4 " thick replaced the back panels. I didnt get to hear them. Any one have input on these mods? How much are new crossovers? I obviously will listen to them before I make any changes. I'm new here and just to fill you in, I listen to vinyl rnr, jazz, occasional classical. My source is thorens td 150 and 145 through a marantz 2235 and a marantz 2275. Just got back into audio and really having alot of fun. Thanks for any input. Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted March 23, 2006 Share Posted March 23, 2006 Congratulations on your new arrivals. Actually I will give advice that is a bit at odds around here. I would suggest not doing a thing to them for the next several months. Simply get used to them. Take some time on positioning them both in the the room and relative to your listening chair. This can easily go back and forth for a couple of months. Try rearranging the furniture also. I am serious. This could have a much more profound effect. Enjoy, -Tom Quote Link to comment Share on other sites More sharing options...
ScorpsFan Posted March 24, 2006 Share Posted March 24, 2006 Gotta agree with PrestonTom, best tweak for my Heresy II's was to place them on the angle stands to point them up and to toe them in a bit. That way, their output appears focused so sounds like voicing come directly from the center of the 8' area between each speaker. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted March 24, 2006 Share Posted March 24, 2006 Best bang for the buck update on crossovers is simply to have the caps replaced. BEC (Bob Crites) can do this quite reasonably. Your Heresy's will sound like they did when they left the factory, which was BTW, very good. They will probably sound good when you set them up. 23 years is along time for the caps on the crossovers though, and they have probably drifted off spec. Fresh caps and you will be delighted with the sound. Quote Link to comment Share on other sites More sharing options...
hwatkins Posted March 26, 2006 Share Posted March 26, 2006 Couldn't agree more with Dee here. In my book the Heresy is the best bang for the buck speaker I have ever encountered (excluding DIY) and I suggest refreshing the caps and listen for a bit as they were intended to be heard. In the end most folks would rather upgrade the tweeter which really can be quite good. Again - BEC is a good source for all. Quote Link to comment Share on other sites More sharing options...

bhendrix Posted March 26, 2006 Share Posted March 26, 2006 Hey, Bob, have you tried the Crites 125 tweeter in a Heresy with the crossover lowered to 4500Hz? That may sound really good. I still have the 125's in the CornScalas and continue to be delighted with the openess of this combo. Quote Link to comment Share on other sites More sharing options...
Deang Posted March 26, 2006 Share Posted March 26, 2006 With a first order filter, you should maintain at least a three octave spread. Quote Link to comment Share on other sites More sharing options...
bhendrix Posted March 26, 2006 Share Posted March 26, 2006 Hi Dean, Does a three octave spread mean that the lowest c/o point for the 125's in a Heresy would be 5600Hz? (700 - 1400 - 2800 - 5600) Please help me understand why . . . Thanks!! Quote Link to comment Share on other sites More sharing options...
BEC Posted March 26, 2006 Share Posted March 26, 2006 I haven't personally tried that. But, DaddyDee has a set of Type E Crossovers modified like that to try in Heresys with the CT125 tweeters. I don't know if he has installed them yet. Bob Crites Quote Link to comment Share on other sites More sharing options...

DrTUBE Posted April 1, 2006 Share Posted April 1, 2006 Hello I read quickly the suggestions of the specialists, and I agree : test your HERESY speakers "as is" before ! But I can give you some suggestions for an improvement of your HERESY 1, as I (and one of my friends) have got the same speakers. Personnally, I felt that tweeter and squawker (mid) were to high in level, even when placed in a corner or in a shed. Taking some measurements showed that the K77 and the K53 were about 10dB over the efficiency of the K22 (woofer). In addition, the impedance curve showed a huge bump to nearly 80 ohms between 3 and 5KHz. This doesn't work with my amps, and probably will not work very well with your amps too (heavily feedbacked I think). Please find the schematic of the Xover mod I have done on my and my friend's HERESY 1. I insist that this mod is EASILY installable and removable, without altering the original KLIPSCH components. If you are interested by the measurements, please let me know, I'll try to send it to you. This mod decreases the levels in a far more correct way, and make the impedance bump quasi-dissappear. And of course, tone is much better... But it's nevertheless a matter of personal taste ! Quote Link to comment Share on other sites More sharing options...
