fourxjake Posted July 8, 2001 Share Posted July 8, 2001 Last weekend I completed a long awaited upgrade to my 1979 Cornwall 1's. I had wanted to upgrade the crossovers for quite awhile as I suspected a problem with one. I had lost 2 tweeters over the years in the one speaker and it didn't sound as crisp and loud as the other. Anyway I was excited when Al K. offered the Cornwall upgrade and decided to construct a pair. All ordered items came very quickly ( 1 week ). I also elected to use 1% tolerance North 5.6 ohm wirewound resistors in the crossovers as well as Teflon insulated silver wire, 14gauge, to rework all internal cabinet wiring to the squaker/ tweeter. I used 10 gauge input wire and to the woofer. I'm very please to report the results are spectacular. Al should be awarded some type of design award! These crossovers bring these masterpiece speakers to a whole new level. The quickness of their response is unreal. The high end detail is amazing. The do sound totally different than the originals though so be aware. The first song I played, my heart sank as the squawker sounded all destorted. I believe it takes a while to bias all the Harmony/ Hovland caps but I soon came to realize the recording sucked. If you thought the Cornwalls were unforgiving before on poorly recorded music, with Al's crossovers its unlistenable. The ALK crossovers bring the Cornwalls to another league all together. I can tell you that one would have to spend at least $3,000 - $4,000 on speakers to get anywhere near my 22 year old Cornwalls with Al's units installed.It's amazing what the drivers in these old brutes are really capable of. Needless to say I can go on and on. Overall they are outstanding and highly recommended. I must warn you though, if one is not skilled at electronics and soldering get them from AL. These are more difficult to build correctly than the drawing might indicate. I have an extensive background in the field as well as all the tools to do the job right. If you don't have either, don't attempt to go it alone or you might have a nice pair of bookends. Finally, the completed units are absolutely beautiful with the Solen coils. They are almost too nice to hide in the cabinet! Thanks again Al for a wonderful job! Ken DeGroff Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted July 8, 2001 Share Posted July 8, 2001 Ken, Thanks for the good words! Why don't you post a picture of one of them. I'd like to see it. Al K.

Chris Robinson Posted July 17, 2001 Share Posted July 17, 2001 Folks, I just put in three of Al's networks in over the weekend (2 Cornwall and 1 Belle). I totally second all of Ken's comments above, including his observation of how gorgeous they are. My 12 year old daughter wanted to take one to school for "Show and Tell" ... Anyway, as far as I'm concerned, these networks are fabulous and a wonderful value. Considering how much time we've all spend discussing amps for our Klipsch products, swapping out the networks to a pair of ALK's is likely spending $10 grand on high end amps. I can't believe the beauty of the sound that I'm hearing; I can't wipe the grin off my face. I think Al SHOULD raise his prices for the kind of engineering you're buying. It is unfair to compare his networks to the stock Klipsch networks; they are just too dissimilar. Don't even think about it; just call Al and order a pair today before he actually DOES raise his prices Chris ------------------ Denon AVR-4800 McIntosh MC-2105 (Fronts) Toshiba SD-3109 DVD Klipsch Cornwall I's (LF/RF) Belle Klipsch (Center) Klipsch Heresy (RR/LR) Klipsch KSW-12 sub Quote Link to comment Share on other sites More sharing options...

Jim Cornell Posted July 18, 2001 Share Posted July 18, 2001 OK AL, How much would it cost me to buy enough crossover parts to build 2 pair of crossovers? 4 crossovers!! $1,100.00 is pretty high for me right now, my wife is pregnant again!!

fini Posted July 18, 2001 Share Posted July 18, 2001 Jim, You might consider investing in a vasectomy before the crossovers. I did, and I can tell you I've never experienced tighter bass. Best to leave it to the pros, though. Not a diy project even IF you have the right tools. Quote Link to comment Share on other sites More sharing options...
HornEd Posted July 18, 2001 Share Posted July 18, 2001 Hmmm, fini is as fini does... thereby hangs the xxover tail! Real magic doesn't come cheap. HornEd This message has been edited by HornEd on 07-18-2001 at 10:21 AM Quote Link to comment Share on other sites More sharing options...
Randy Bey Posted July 18, 2001 Share Posted July 18, 2001 so, fini, you recommend a vasectomy to tighten bass response? Quote Link to comment Share on other sites More sharing options...
Jim Cornell Posted July 18, 2001 Share Posted July 18, 2001 Thank you Ed Jim Quote Link to comment Share on other sites More sharing options...
fini Posted July 19, 2001 Share Posted July 19, 2001 Acctually, the vasectomy made my WIFE more responsive. Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted July 19, 2001 Share Posted July 19, 2001 Jim, Sorry I took so long getting back here. I really don't know about the parts cost. I buy the parts in quantity, and direct from the manufacturers, so my cost is probably less than yours would be. YOu will just have to shop around. Al K.

Jim Cornell Posted July 20, 2001 Share Posted July 20, 2001 Al Can i buy a package parts, from you? Im in the Denver area, where do i get these parts at, or is their a website to go for them? If i upgrade one pair ill need to do the other as well!! Regards Jim Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted July 20, 2001 Share Posted July 20, 2001 Jim, No, I'm not into parts kits. All the parts sources are listed in the download from you web site though. Al K. Quote Link to comment Share on other sites More sharing options...
