  1. a little late to the party, nice day for yardwork up here Regarding the tweeter, I have one poly, two phenolic and one titanium diaphragm I just hooked up to the meter. It looks like 8.5 is an average reading between the lot. Parts Express has the polyswitches for peanuts, and if you are in the States the Crites and SimplySpeakers titanium diaphragms are free shipping (over $50). SimplySpeakers looks to have a phenolic “style” replacement too but they are not original equipment. I really liked the titanium TWEETER diaphragms, some don’t, so do your research on those. I recently put the phenolics back in the 301s to sell them and did not find anything immediately lacking in their presentation, they just sound better to me with Ti diaphragms. They sounded even better with Dave A’s LMAHL with the DE-120s, the same lens with the DE-10s needed a little attenuation, to my ears. If you are going to replace one, you may as well get a matching pair and have a spare, that you’ll never use, lol. When you get them up to snuff be sure and let us know your impressions. Cheers,
  2. Covid killed a fair market, too
  3. Maybe this is the replacement ? Interestingly the crossover on this model is 750 Hz, very close to the Cornwall 4.
  4. those are real, and they’re spectacular
  5. yikes, are the tweeters still tweeting ?
  6. @Jeff Matthews, everything changes when you change anything, whatever balance you have now will be different if you take a different path. Whether you like the change or not is entirely your business. Different is fun too, but the engineers had a plan. It looks to me like you have type A crossovers in there right now. I am going to ASSUME the tweeters are the round magnet Alnico version and the K-55 is the single phase plug version as well. The type of drivers in your speakers are an important consideration when choosing a path. There are limits both in frequency response and power handling depending on what drivers you choose to use. If you like the way they sound now, new polyesters will preserve that presentation. Probably make it a little clearer considering the age of those capacitors in there now. @jjptkd’s idea about trying different caps is a great idea. With a little effort and a very small outlay you can be sure which path you prefer. I really enjoyed a pair of Crites A/4500 crossovers I had recapped with polyesters in a pair of LSIs (before Crites offered a copper version), albeit with aftermarket tweeters. When pushed a little harder they held it together better, but at low to moderate levels, the “bright” Sonicaps were more revealing. Your ASSUMED alnico tweeters won’t appreciate being pushed hard, so that is a serious consideration, replacements for them are not falling off trucks. IF I understand the driver complement in your Khorns correctly, I would expect the type A crossover using a K-55 that rolls off at 4500hz to sound very similar to what I was using.
  7. @Kopek, Klipsch had a couple of sleepers I didn’t know about until I found this forum. A little taller and about the same size as the Forte’s footprint, but only in black, the Tangent 4000, and especially 5000 are outstanding performers.
  8. @susan, the crossover and midrange driver might help narrow down the year a little closer if you can get a picture of them
