Def Leper Posted September 8, 2005 Share Posted September 8, 2005 I'm new to the forums, and would like to review suggested Cornwall modification hints. The oft-referred-to thread "Cornwall Mods Glossary" is nowhere to be found. Even a search on "glossary" yields only a few threads where people have referred to this thread, not the thread itself. The search routine is also a bit random, and repeated searches on the same keywords seems to yield different results almost every time. Can anyone post a link to the actual thread? Background: I recently picked up a pair of what were probably among the last Cornwall I-series made, produced the week before Christmas in 1984. I'm replacing a diaphragm in one midrange driver, but other than some veneer wear, the speakers are in excellent condition. I would like to welcome the speakers to a new millenium with some modifications that will offer improvements that a deaf old geezer can hear, but that will not make them look like the south end of a northbound DeLorean time machine.

intotubes Posted September 8, 2005 Share Posted September 8, 2005 A crossover upgrade or capacitor replacement is supposed to yield the best results as far as audible modifications go. Some have added a brace in the cabinet (newer CW's have a front to back brace). If you change your mind and want the DeLorean, you can turn them into a "CornScala" or a DBB (double bass bin).

Deang Posted September 8, 2005 Share Posted September 8, 2005 That was the year of transition. Before making any modifications - identify the drivers and networks. We need to know what you have in there. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted September 8, 2005 Share Posted September 8, 2005 ARRRRRGGGFKGGGGGRRRRRR I started that thread and a ton of work went into it. I looked too, it's gone???? Maybe it was one of the ones that didn't make the transition--- yet? There were a lot of photos and diagrams on it. Michael I was able to SEARCH and find them on the old bulletin board. http://forums.klipsch.com/idealbb/view.asp?topicID=51942&forumID=71&catID=19&search=1&searchstring=&sessionID={BA2BC161-428D-42B5-B843-A35DB0134D73} Quote Link to comment Share on other sites More sharing options...

colterphoto1 Posted September 8, 2005 Share Posted September 8, 2005 Great, now BillH will want Cornwalls! It cost you a fortune to come over here to sell me those KG's, didn't it? LOL Michael Quote Link to comment Share on other sites More sharing options...

colterphoto1 Posted September 8, 2005 Share Posted September 8, 2005 uh, yaaaa. Those be fairly modern Cornwalls. You don't have to do the caulk mod with the K601 horns. I'm told the K57 is as good as the K55. I have this configuraton in my parts bin for my single vertical center Cornwall. Michael Quote Link to comment Share on other sites More sharing options...
D-MAN Posted September 8, 2005 Share Posted September 8, 2005 I don't think the search function goes past the date that the forum software got "upgraded". You got to search the earlier history threads by hand. Some fun! DM Quote Link to comment Share on other sites More sharing options...
Def Leper Posted September 12, 2005 Author Share Posted September 12, 2005 Is there any consensus from forum participants about the new Cornwall type-B crossovers offered by Bob Crites on ebay? As mentioned before, my late-model Cornwall I's have the B-3 crossover. Also, thanks everyone for the comments on the original thread. I think I'm going to pass on the solid silver wire for the speaker connections and apparently my later model midrange horn doesn't need damping but the woofer brace seems like an easy and useful mod, along with perhaps the felt sealing gasket for the rear hatch. I might do the crossovers, too. Any opinions on the following from the aspect of negative impact on sound quality? -Eliminate grill cloth system -veneer the front plate (no kids to poke fingers in drivers) -1" riser -front to back tensile brace to preload the front and back plates (maybe two of them) Thanks again for all the helpful replies.

Replace the old caps Install the additional 3/4" sheet over the back plain Brace the motor board Replace the K600 lens Replace the mid driver Replace the K77 In that order of improvement Regards, Terry Quote Link to comment Share on other sites More sharing options...
