And why do you think the aluminum tweeter sounded better than the titanium tweeter I read a lot of positive things about the titanium Tweeter namely They are made by a forum member. I've used them for my Heresys and now my La Scalas. They give you a wider sound stage of natural highs, and are very engaging. My titanium tweeter upgrades were brighter, but far less natural and narrow by comparison. If cost is a factor, do the titanium. If it isn't, get these instead: https://www.ebay.com/itm/224152702930?hash=item34308acfd2:g:6jcAAOSwBF5d5TWS Quote Link to comment Share on other sites More sharing options...

No, it's a completely new, aftermarket custom design with a significantly higher quality compression driver. 10 hours ago, Flevoman said: And why do you think the aluminum tweeter sounded better than the titanium tweeter The horn lens is Aluminum but the compression driver diaphragm material is actually Mylar and quite a bit larger at 1.4" 10 hours ago, Flevoman said: I read a lot of positive things about the titanium Tweeter namely The titanium diaphragm upgrade is nice but not entirely different than stock-- a little more detailed and smoother at higher volumes from my experiences but not night and day differences. If you opt for @Dave A tweeters I'd contact him directly through the forum will probably save a little cash versus eBay as they charge fees and taxes. I'd go for the B&C DE-120 driver as they will drop right in the cabinet opening and they're a great sounding driver. https://www.parts-express.com/B-C-DE120-1-Neodymium-Mylar-Compression-Driver-8-Ohm-2-3-Bo-294-5809 1 2 Quote Link to comment Share on other sites More sharing options...

But doing a recap, damping the midhorn or perhaps a titanium diaphragm should fix this It really sounds to me like you need a recap of the crossover that is where I'd start. 1 Quote Link to comment Share on other sites More sharing options...

001 Posted March 9, 2022 Share Posted March 9, 2022 just to clarify the aluminum tweeter thing, the aluminum is the horn casting itself that the member here sells & then uses a different diaphragm. the titaniums use the original plastic horn housing but replaces the original diaphragm with titanium. the alum horns are very nice from the reviews ive read but they are very expensive so all comes down to budget. the titanium diaphragms are a different sound signature than the stock ones, its not equivalent to just turning up the treble knob... they have a crisper sound or as mentioned more "sparkle" & are smoother over their freq range than the originals from my experience with them & what many others that have them describe. 1 Quote Link to comment Share on other sites More sharing options...
Flevoman Posted March 9, 2022 Author Share Posted March 9, 2022 Thanks for the explanation because I did indeed misunderstand. 😅 I thought there were two types of diaphragm, aluminum and titanium OK,it's a whole horn Nice to know this. Next Monday my tube amp will be modified along with the caps of my filter. After this I will continue to see what I can do about mods., I put this as an option.. Thx for sharing 👍🏻 1 Quote Link to comment Share on other sites More sharing options...

Not particularly so since you sell off the old drivers. Looking on EBay will give you good numbers on what you can expect to get and that reduces your overall cost. Tonight K-76 tweets for example are listed for a minimum of $75 each so $150 per pair assuming they sell for that. 1 Quote Link to comment Share on other sites More sharing options...
Flevoman Posted March 10, 2022 Author Share Posted March 10, 2022 (edited) I wouldn't sell my old drivers I guess But indeed this is not very expensive (edit) Or do I misunderstand you and are the k-76 drivers the old drivers and is this the amount they are still worth Edited March 10, 2022 by Flevoman Quote Link to comment Share on other sites More sharing options...

captainbeefheart Posted March 10, 2022 Share Posted March 10, 2022 I wasn't saying the crossovers weren't original with my comment about the resistor, I was commenting on what another person noticed that the resistor type in the network looked to be swapped out by someone at some point.

billybob Posted March 10, 2022 Share Posted March 10, 2022 @Flevoman...I suppose you have gotten a crossover out of speaker? If so, how about a photo of one from the side now... thanks!☕ Quote Link to comment Share on other sites More sharing options...

Since I like to listen to music every night and I don't have to hand over the tube amp and filters until Monday But I will definitely post the pictures here. I am also curious whether or not they are orriginal. Edited March 10, 2022 by Flevoman 1 Quote Link to comment Share on other sites More sharing options...

All the older 2.5cm tweeter lenses have the same size and shape and only the motor is different and perhaps the diaphragm too. The more modern 2.5cm tweeter first appeared in the KP-301-2 if I remember right but all of them fit the same size cutout. There are no K-79's listed right now at any price.

Flevoman Posted March 11, 2022 Author Share Posted March 11, 2022 (edited) If that is true then this would indeed mean that the caps are more than 35 years old. And then the chance of hearing a difference after the recap is more plausible. 😁👍🏻 (edit) I now see that from the left large silver block the screws are completely turned out. I think this is done so that the block can tilt so that you can pull the filter out through the back. This is what I'm going to try 👍🏻 Edited March 11, 2022 by Flevoman Quote Link to comment Share on other sites More sharing options...

I stick an Audyn 68uf cap on there and not one of those electrolytics. Just got done working on a KP-301 which is very similar where that electrolytic cap was swollen and the plastic melted off part of the side. I would not loosen those screws as the input cup crossover might be real tight to get in and out but I have never had much trouble doing so. If you do then remove the woofer so you can tighten them back up. This is assuming they were tight when you removed them and that you loosened them for re-assembly.

Yes the Tractrix tweeter lens first showed up in the pro line in the "II" series; 201-II, 250-II, 301-II etc around 2000. These all started off with the shiny black Poly diaphragms until they eventually switched over to Titanium. I've sold several sets of the k-75, k-76 and k-79 tweeters over the years by the time you subtract seller's fees and shipping costs you can typically count on $100-$120 net in your pocket.
