So now I will have to change my tweeters? or will it be just fine? I can wait to hear what my lascars are supposed to sound like You will not have to replace tweeters. The Type AA is designed to be used with the stock K-77 tweeter. Like @jason str said, if you switch to the A/4500, then you would need to change to a more robust tweeter as the K-77 crosses at 6000 Hz and will not survive the lower 4500 Hz XO point. 1 Quote Link to comment Share on other sites More sharing options...
klipsch1 Posted November 10, 2017 Author Share Posted November 10, 2017 I just bought this pair of k77 from eBay and I'm wondering if a made a big mistake? they don't have the Klipsch badges on the back. are they original klipsch or after market? will it make a big difference if they are 8 or 16 ohm? I paid $225 Canadian with shipping Quote Link to comment Share on other sites More sharing options...

They are pretty well marked as Klipsch K-77. I'm not sure what you mean by "badge." I can tell you the wires look exactly like OEM Klipsch wiring. It does make a difference if they are 8 or 16 Ohm. I believe the K-77 is 8 Ohm, the K-55-V mid driver is 16 Ohm. Quote Link to comment Share on other sites More sharing options...

They were designed to be used together. I only mentioned the K-55-V because it uses the fairly unusual 16 Ohm driver and you asked about 8 Ohm vs 16 Ohm in the K-77. Sorry for the confusion.

klipsch1 Posted November 10, 2017 Author Share Posted November 10, 2017 what would be the difference between the k77 round back with the badges and ones with out the badges? Quote Link to comment Share on other sites More sharing options...
Deang Posted November 10, 2017 Share Posted November 10, 2017 Those are nice, quit stressing. Those are what we call round back K-77s, and have Alnico magnets. They don't have the quite the extension of the newer square magnet types, but the Alnico magnet K-77's have a large following. The part numbers can get confusing. "K-77" is the Klipsch designation. Early units were made by University, and were referred to as the T-35) Later units were made by Electrovoice. The earlier, round magnet versions are not quite as robust, so be sure to use, or reuse the zener diodes that are in the tweeter circuit of the Type AA. Early versions of the driver came in both 8 ohm and 16 ohm versions. It does make a difference -- do you know what you bought? A nice thread was recently started on these ...

klipsch1 Posted November 10, 2017 Author Share Posted November 10, 2017 I actually asked the seller to cancel the transaction. I have la Scalias with k55v with spring connectors . I'm going to put in k55v with the soldered connection and I also purchased a AA crossover rebuild kit from bob crites. Now the reason for my initial question was because the lasacala had 1 round k77 in it and the other cabinet had a square k77. So I wanted a matched set of round k77. What is better 16 ohm version of k77 or 8 ohm version ? one set has metal badge on the back and the other set of k77 doesn't. what is the major difference . thanks Quote Link to comment Share on other sites More sharing options...
Deang Posted November 10, 2017 Share Posted November 10, 2017 Don't worry about the "badge" issue, all that matters is whether they are "Klipsch" or not. 8 ohm is preferred, which is what was used with the Type AA crossover network. Tell the seller you want DCR readings from a multimeter. This will confirm 1) that the diaphragms are good, and 2) what impedance the drivers are. 2 Quote Link to comment Share on other sites More sharing options...
muel Posted November 10, 2017 Share Posted November 10, 2017 From the different versions I've heard I don't think you are going to hear any difference between those assuming they are functioning properly. Slow down and get your caps replaced. One of the mistakes I have made is changing multiple things at once. Make a change and live with it for a week or two to get a feel for it before you do anything else. 1 1 Quote Link to comment Share on other sites More sharing options...
