Jdiesel87 Posted May 13, 2023 Share Posted May 13, 2023 I just grabbed a pair of Quartets in Oiled Oak sight unseen for $400CAD today. Cosmetically they are pristine, unfortunately, when I got home and hooked them up something seemed "off". Messing around with my calibrated microphone I was able to confirm that there no output above 8000khz and when I popped out the tweeter assembly and measured the resistance with my multi-meter confirmed that they were both shot. I am conflicted about whether I should replace them with something similar to stock or go with titanium diaphragms. Seeing as I've never heard them with any tweeters I have no frame of reference to base my decision off of. I will also likely be replacing the capacitors in the crossover network at the same time as well. Other than Bob Crites for the titanium diaphragms, is there another reputable source for K-76 diaphragms. I am located in Canada which may influence my choice. Looking forward to getting these up in tip-top shape. 1 Quote Link to comment Share on other sites More sharing options...

Good morning and congrats on the new Quartets! It wasn't that long ago TI tweeters were pretty much the norm around here wherever they were sourced from and Klipsch has used them in their extended Heritage line for almost 15 years or so. As part of my refresh efforts when buying these speakers that was one of the first things I'd do is swap these old tweeter Diaphragms out. As far as parts sources goes Speaker exchange and Simply Speakers are good resources they have a lot of factory parts: https://www.simplyspeakers.com/klipsch-replacement-speaker-diaphragm-k75-d-417.html?redirect=1 1 Quote Link to comment Share on other sites More sharing options...

I just went ahead and order the titanium ones from Bob Crites. I feel like as far a modifications from the original design, Bob's titanium diaphragms are very regarded and acceptable drop in replacement and an overall improvement. It ended up being a bit more than I would have liked to spend but I feel like I will still be well ahead bases on the price I pairs for the speakers and their condition. 1 Quote Link to comment Share on other sites More sharing options...

Jdiesel87 Posted May 15, 2023 Author Share Posted May 15, 2023 Titanium diaphragms are on the way! I threw in a capacitor kit just to have as I wanted to optimize the shipping costs. I just went with the "copper" level caps because I suspect they are the closest to stock as possible and I was worried about swing to far to the bright side with the upgrade diaphragms. At first I had planned on just replacing the diaphragms and leaving the crossover be but the more think about it I like the idea of just doing it all now and being done with it. 1 Quote Link to comment Share on other sites More sharing options...
Iteachstem Posted May 15, 2023 Share Posted May 15, 2023 If you don't like the Ti diaphrams ( I didn't when I put them in my KLF 20's) simply speakers has a nice set that's easier on the ears for $20 and if you buy it from their ebay store they are usually $19 each with free shipping. https://www.ebay.com/itm/114931807079?hash=item1ac2783367:g:OSAAAOSwV1BhFFKE&amdata=enc%3AAQAIAAAAwBwtcPz9UFhIRoIbVPArgk2aTiUhzll1RlPPIvK%2Fly5ewSHJNaGEaQK3ZJsF7CgCn8DPZbjZUhupzqz6jIlcdoVauj30DEKohR14L3XTkJ29aZwx1bIBSATuj9KTbpbvxmYUK123RWywHoVMdVyOvBgVfSUAp4TfW0hSlB6bmkiV41P6xsQk0ublazLSVpKwXSoywT1Yqs%2BiAAuGHecmW%2BEK3mUIKwkgMrvPHtP2%2BZGO6vYa7m4qrqjnCYPkP6beBw%3D%3D|tkp%3ABk9SR7yv-oeEYg Quote Link to comment Share on other sites More sharing options...

You should swap the diaphragms first maybe give them a couple days before replacing the caps that way you know what change you're hearing. 3 Quote Link to comment Share on other sites More sharing options...

Is there any possibility that a damaged crossover network could have been the root cause of the diaphragms going in the first place? I'd hate to replace them and have the new ones go on me too. That is my only reason for doing everything at once, I agree with your otherwise with the single tweak and listen approach. Quote Link to comment Share on other sites More sharing options...

Tweeters are typically the first thing to go when the volume is pushed too high I've had to replace several pairs of them over the years back in my party days, Had a friend with CH-II's out in his garage with Carver A-760x (380x2) and had to replace his a couple times. I've bought and sold dozens of Klipsch speakers over the years with that tweeter type and never once seen a faulty crossover be the cause of a bad tweeter, not saying it couldn't happen just based on my experiences probably not. Another option would be to do the re-cap first and let them settle in for a few days, get used to the sound that way then replace the diaphragms but then you wouldn't know how they would sound with the factory crossovers.

Jdiesel87 Posted May 16, 2023 Author Share Posted May 16, 2023 Thanks I will just do the diaphragms for now. I do have an LCR meter that I can test the caps with, if they are in spec I will leave them. Quote Link to comment Share on other sites More sharing options...

Cap choices have been debated here for decades (subjective sound qualities) now the only "approved" choice on this forum is JEM, which if staying true to factory spec is your goal it's really the only choice. As far as the tweeters I've tried them all seriously doubt you'd be be able to tell a difference between the ones you bought and factory but it is nice to stay with OEM when you can.

Jdiesel87 Posted May 16, 2023 Author Share Posted May 16, 2023 (edited) On a side note, I have really been enjoying the speakers even without the tweeters. I spent the last few days listening and think I settled on the best position for my 13'x24' room. Speakers on the short wall, about 3' from the side walls, 7" from the back wall, and toed in slightly with the main listening position about 9' away. I not able to put them right into the corners like many suggest due to the placement of my turntable and record stand. I find the bass to adequate but not boomy. Music sounds lovely on them but I've noticed that vocal/speech sounds a bit muffled or veiled, almost like something is speaking from the next room over. I especially notice this if I put on a movie or show. I don't know if the tweeters will make a huge improvement on that front but I don't want to cast a final judgement until they are replaced.

winglet Posted May 16, 2023 Share Posted May 16, 2023 Functioning tweeters will make a HUGE difference. My quartets are far from muffled sounding. Quote Link to comment Share on other sites More sharing options...

Placement sounds about spot on with my experiences any closer to the corners and bass gets stronger but the soundstage seems to collapse Tweeters should make quite a bit of a difference but these speakers are high sensitivity so good source will result in good sound not sure what gear you're running but that can make a huge difference if playing digital files or streaming I'd recommend something with a newer / good DAC or decent stand alone DAC.
