Olorin Posted March 19, 2005 Share Posted March 19, 2005 It seems to me that there used to be one of those, but now I can't find it. Am I imagining that, or is there really an ALK Heresy Type E mod? If there is, is it public domain and available in schematic form? Quote Link to comment Share on other sites More sharing options...
J.4knee Posted March 19, 2005 Share Posted March 19, 2005 I just looked and did not see it either. Al....... Quote Link to comment Share on other sites More sharing options...
jorjen Posted March 19, 2005 Share Posted March 19, 2005 There is an "E" Type ALK for the Hersey, I made a set that DeanG wound up with. It is the same ALK network designed for the Cornwall but with a different value swamping resistor. The Cornwall network uses a 5.6 0hm 10W and the Hersey network uses a 4.7 ohm 10W.

tigerwoodKhorns Posted March 19, 2005 Share Posted March 19, 2005 You are talking about a very expensive crossover for a $400 set of speakers. Bob crites can will sell you a set of caps to rebuild your E's pretyy reasonably. If you like, you can add a solen inductor for about $20 ea. There is also a mod to lower the squaker and use a 16 ohn resistor to make up teh difference. Chris Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 19, 2005 Share Posted March 19, 2005 Since Heresys list for over $1100, you might consider the cost of the ALKs a good deal. Marvel Quote Link to comment Share on other sites More sharing options...
Olorin Posted March 19, 2005 Author Share Posted March 19, 2005 Tiger, I'm aware of the relative costs of Heresys and crossover mods. I'd DIY whatever I decide to do, and that's why I asked after a schematic. If the schematic is not freely available it's really not a big deal -- I'll just replace my original caps with some Kimbers or Auricaps or something. The ALK question is as much about satisfying curiosity and knowing what options are available as anything else. Jorjen, thanks for the info. I thought there wasn't much difference there, and thanks for elaborating on just what the difference is. Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 20, 2005 Share Posted March 20, 2005 Olorin, you have PM and email. I checked after I emailed you. The package is still available on Al's site. Go to www.alkeng.com scroll down the left frame to the klipsch icon, then scroll down to the download section, then down to the "B" network download. It's the whole package in a .zip file. BTW, the Cornwall B becomes the Heresy E with one minor part change, which is detailed on the plan. Quote Link to comment Share on other sites More sharing options...
ttaylor Posted March 20, 2005 Share Posted March 20, 2005 The schematic is still on the ALK site. http://www.alkeng.com/dload_xo.html I had previously thought that this crossover might be overkill, but since doing a host of mods to my Heresys, I may well build them myself. Mine have made a fairly good leap forwards in terms of sound quality. Before the mods and while still owning La Scalas, I dismissed the little Heresys somewhat as being mediocre. But now, with a good, equalized sub, they are probably worth the cost of ALKs in terms of investment in sound. I will never sell them, so resale doesnt factor in. And I cant think of another, compact, high efficiency, dynamic speaker for the $700 Id have in them so..... Ive used Solens and air core inductors, which definately improved things BTW. Keep us posted if you build them. taylor Quote Link to comment Share on other sites More sharing options...

Tom Mobley Posted March 20, 2005 Share Posted March 20, 2005 wow, you're fast. be sure to read and understand the last paragraph of the cwdesign.txt file, it has a good suggestion on using different transformer taps to attenuate the mid and high to match the smaller woofer better.

Olorin Posted March 20, 2005 Author Share Posted March 20, 2005 Me, fast? Just don't tell my wife. I did see that about the taps. I infer that has to do with the difference between the K-33 and the K-22? I haven't sat down yet to really study the ALK vs. the stock Type B vs. the stock Type E. It makes sense, though, that when you start crossing the Corwall at 700+ you've gotten yourself really close to a Heresy crossover. It's another one of things that is obvious after you know the answer. :-/ As for the actual build, I figure when I get my Heresy collection large enough I'll be able to A/B the ALK vs. just replacing the aged components with new equivalents. That ought to help me make up my mind, which otherwise seems to have a hard time sitting still. Thanks again. O Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted March 20, 2005 Share Posted March 20, 2005 yeah, it compensates for the smaller, less efficient woofer. >>>It's another one of things that is obvious after you know the answer. :-/ I'm sure that's why God made smart guys like Al, to make things obvious for the rest of us.

Olorin Posted March 21, 2005 Author Share Posted March 21, 2005 Hey taylor, I just reread your post. Sorry I missed replying to you the first time around. You like the Solens? I think I'm going to start by replacing the existing caps with some Kimbers and see where that gets me. That looks to be a good bang/buck proposition, and the ALK schematic is intimidating, frankly. I should start with baby steps. Aside from the crossovers, how else have you modded your Heresys? What you said about the sub caught my eye. See my post "I think I've been had" in General -- seems we agree on that point. O Quote Link to comment Share on other sites More sharing options...
ttaylor Posted March 21, 2005 Share Posted March 21, 2005 Hi Olorin, You can check out this post for pics and a discription. http://forums.klipsch.com/idealbb/view.asp?topicID=61828&forumID=71&catID=19&search=1&searchstring=&sessionID={D26EA750-6258-4566-BDFC-E868B97E4256} Basically, I damped the cabinets, ran a brace between the side panels and mounted the drivers on the front of the baffle. The damping has really tamed the overly "live" (read PA) sound. The bass and midbass is far more articulate and tight. And the imaging, which I never considered Heresys having, has improved greatly. Allowing the horn flares to radiate out as designed,and from a flat baffle (no wood trim and grill protrusions) really has changed the quality of sound. The HF is now airy, and the mids arent as hot. And the sub...well, its now manditory IMHO. Cheers, taylor Quote Link to comment Share on other sites More sharing options...
Olorin Posted March 21, 2005 Author Share Posted March 21, 2005 Wow, REALLY nice work. I love the front-mounted horns, but I'm not sure how thrilled I am with the idea of grinding on my horns. The things we do for love! Quote Link to comment Share on other sites More sharing options...
jorjen Posted March 21, 2005 Share Posted March 21, 2005 Olorin, This is a set of ALK's I made for some Cornwall's I refurbed. The ones I made for the Heresy's were identical except I used Solen's in the Heresy's and AudioCap PPT Thetas in the Corn's. Just for something different. I later built a set of "A" Type ALK's for my Khorns and used the Solen's. Something always bothered me about the top end. Kind of grungy, edgy, just not clean. After trying many different things to correct this with no luck, I finally thought I would try replacing the Solen's with Hovland's and guess what....problem solved. Some might say that the Solen's are good enough, I don't buy it, at least not in the top end anyway.IMHO. Quote Link to comment Share on other sites More sharing options...
jorjen Posted March 21, 2005 Share Posted March 21, 2005 Here is a pic of the "A" Types with the Hovland's. Kind of pricey I know, but worth the difference let me tell you. Quote Link to comment Share on other sites More sharing options...
jorjen Posted March 21, 2005 Share Posted March 21, 2005 I know these are not for the Heresy, but I thought you fellas might like to see them anyway. Hope I am not stepping on your thread. Quote Link to comment Share on other sites More sharing options...
