I have a pair of KG4 3-way speakers by Klipsch. One sounds great but the other has a buzz that emanates from the tweeter horn. For the most part the speaker sounds good, but there is a background "fuzzy" noise coming from it. I pulled out the tweeter to make sure that was the problem and alas, the buzz stopped. I could not, however, find any damage to the dome assembly. The other tweeter sounds fine. I went ahead and purchased an aftermarket dome for the horn, but upon installation I found the replacement to be oversensitive and harsh, not warm like the original domes. Could anybody explain what this buzz is?
I cannot find any dirt in the magnet. Also, the new voice coil has no buzz, and it's VC has about twice as many windings as the old one's.
Does anybody know a reliable part supplier that may have something factory, even if it is used?
This looks a lot like the original, but it's ebay...

I'm a bit confused, since the driver at the back of this horn is by definition a 'compression driver' & not a plain ol' tweeter. Is it a screw-on type or ???.
My guess is, the driver at the back of this horn is a true compression driver, & you "tried"? to put a "typical' tweeter in its place. A regular tweeter trying to push that air mass in the horn will sound all wrong, distort the tweeter diaphram & all sorts. It would be best to replace it with an original driver.

There are 3 nuts that bolt it all together. The part I got claims to be a replacement for this tweeter assembly. The replacement diaphragm appears to be very similar to the original, outside of a larger VC. Does that answer your question?
Ok, I got it, strange? In "pro-sound" compression drivers are divided up by throat size, One inch & two inch, screw-on types (1") and two-bolt, three-bolt (A few) and the "big" Four-bolt types. Being as Klipsch "does their own thing", it would seem they are a proprietary driver. Pro-sound compression drivers are rather giant things appx 6-8 inches in diameter!
I'm surprised somebody makes a replacement driver for your Klipsch. It would seem that these drivers are not an exact match......best guess but not exact.
I would try to get a hold of Klipsch....perhaps their customer service could direct you to that "perfect" match.
Being that Klipsch is such an old & well established company, I would tend to think they can get right on top of your situation.....finding you an exact replacement driver....& perhaps knowing exactly why your driver is sounding bad. My guess outside of dirt & dust contaminating the VC is a fractured diaphragm.

You can every part you need form crites speakers. They make high quality replacement diaphrams for nearly every klipsch speaker ever made. they also make replacement cross overs in kit and finished form. I replaced the diaphrams in my KG-4s with the crites titaniums when I refurbished my speakers. They are a huge improvement and were a perfect fit. I have a hard time trusting products I find on ebay...maybe thats just me. cheers.
I contacted Klipsch and they didn't help much with diagnostics. They also don't have any replacement diaphragms, but the representative pointed me to this product:
Klipsch Replacement Speaker Diaphragm K75, K76, K78, K79, 127103, D-417
I looked at Crites, and a set of his tweeters are $70. Being a college student, that kind of investment is a fairly large chunk of change, and I would much rather go for this $35 route.
That being said, I don't want to buy trash. The dome pictured in the "simply speakers" page looks a lot like the cheap aftermarket dome I purchased previously, but the VC is smaller, more closely matching the factory coil.
Can anybody give me some insight on this product?

The diaphragms at simply speakers look kind of cheap. They might cure the buzz but they might not sound as good as they could. Might....who knows. The kg4 is a great speaker and well worth the effort of repairing the right way. Do yourself the favor and save up a little and get the highest quality replacement parts you can. After I replaced the functioning factory diaphragms in mine with the crites I decided they sounded so good that they deserved a proper face lift with all new veneer and dozens of coats of tung oil. Just my 2¢😀

Three driver two way speaker, dual woofers with a passive radiator and a horn mid/tweeter horn.
Save the money and buy the Crites titanium diaphragms they are in my opinion the best you can get, I think they are better than the stock Klipsch ti diaphragms in my H3 which I have since replaced with the Crites diaphragms. I have used six sets of the Crites diaphragms and find them to be excellent. make a thin gasket to interface between the diaphragm and the motor assembly. A single layer of skived Teflon tape the thin version plumbers use is excellent and you wont have any buss from a mechanical source. Crites ti diaphragms come with a very thin gasket. Hope this helps. Best regards Moray James.

Okay, thank you for the advice! I'll save up and get them, guess I have to deal with the white background hiss for now.
