profsbg Posted January 10, 2007 Share Posted January 10, 2007 Considering bidding on Klipshorn at http://cgi.ebay.com/Pair-of-Klipschorn-Speakers_W0QQitemZ280068533468QQihZ018QQcategoryZ61378QQssPageNameZWDVWQQrdZ1QQcmdZViewItem. Can someone provide input on what is needed and approximate cost of upgrade (drivers, networks) to bring them up to top form. Thanks!

soundbound Posted January 10, 2007 Share Posted January 10, 2007 Caps should be replaced because of their old age which does not cost to much. Bob Crites a forum member here sells good cap replacement kits on eBay. He sells new crossovers too if you'd rather. I use a set of his crossovers and really like them! Link provided below. I'd go ahead and do new wire while at it. New wire cost so little. Drivers are hopefully OK and last a very long time. I replaced all mine, but that's just me. Most do not. I heard a big difference, but mileage may vary. http://search.ebay.com/_W0QQfgtpZ1QQfrppZ25QQsassZbobcritesQQssPageNameZSTRKQ3aMEFSQ3aMESOI Quote Link to comment Share on other sites More sharing options...
ben. Posted January 10, 2007 Share Posted January 10, 2007 Well, it depends on what you mean by "top form". I have 76s and I found that replacing the stock AA network with a type A built with Jensen PIO capacitors was a significant improvement. It increased the HF energy to provide clarity, but was still quite smooth due to the choice of components. It's really a matter of taste and listening habits, not to mention system synergy (including the room). I'd counsel you to buy them if they are within your means and practical to pick up. The BIN is fair, even considering the condition. Local Khorns are not all that easy to find. Listen to them (constantly - as if you'd be able to stop) for at least a month to evaluate what needs improvement if anything. Barring any gross defect, the networks seem to be the first thing folks here ditch. Not that the originals were a poor design or junk, but after 30 years, the components are likely to fall short of acceptability. Network upgrades seem to be $200-500 or so. They can be quite a bit cheaper if you can solder, read with comprehension and have the inclination to attack them yourself. Quote Link to comment Share on other sites More sharing options...
Corvette6769 Posted January 11, 2007 Share Posted January 11, 2007 You may wish to ask the seller some history on these. I see that someone has changed components on the balancing network (crossover) on serial number 6N811 but not the other one. If it were me, I would want to know why.

profsbg Posted January 11, 2007 Author Share Posted January 11, 2007 Thanks for the advice all. I sent the seller an email asking about the network in 6N811. Good eyes Corvette6769! Quote Link to comment Share on other sites More sharing options...
profsbg Posted January 11, 2007 Author Share Posted January 11, 2007 Seller says that tweeter failed and Klipsch replaced tweeter and network. Unclear why they would replace with different parts in network, perhaps what Klipsch had available?. Also, how common is it for tweeters to blow in these things, does this mean it was being pushed too hard? I guess it isnt easy to determine the answers to these, but any input is appreciated.

BEC Posted January 11, 2007 Share Posted January 11, 2007 Sounds like Klipsch thought that the tweeter may have failed because of a proplem in the tweeter protection circuit on the network. Probably the networks are the same type, just different capacitors used at the time the replacement network was made. I wonder if the tweeters are different also. If the replacement happened after about 1979, the new tweeter may be a K-77M (square magnet) and the original tweeter a K-77 (round magnet).

JohnA Posted January 11, 2007 Share Posted January 11, 2007 i wouldn't assume they are not in top form as is. listen first and see what they need. Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted January 11, 2007 Share Posted January 11, 2007 This is way out of sequence. First: Buy the Speakers Second: Enjoy them Third: Fool around with their placement and snugging them into the corners Fourth: Continue to enjoy them It is far too early to worry about swapping crossovers. If you are worried about the caps being old, then Fifth: Spend $20 bucks at Parts Express and get some Solens (no need to go overboard at this point with fancy caps etc) Sixth: Continue to enjoy them It is not as bad as it used to be, but for awhile it seemed that the mantra around here was "immediately modify your Klipschorn...." They actually sound pretty good as they are. Good luck on the bidding, -Tom Quote Link to comment Share on other sites More sharing options...
ben. Posted January 11, 2007 Share Posted January 11, 2007 N in the serial number indicates 1975. Wouldn't worry about it - they could've been purchased in 76... Quote Link to comment Share on other sites More sharing options...
