Question: it seems like I have a good original set of early Cornwall II's with desired component drivers. The can style capacitors have a lifespan, so replacing them is expected in order to maintain sound quality. It seems that replacing them should not detract from their originality. There are multiple options for updating the capacitors. None of them, to my knowledge, are an exact replacement. There's the Dayton/Sonic path (among others, I'm sure) and the JEM path. From what I'm gathering, the JEM supplied capacitors might be a better match to the original. That seems like a good goal to me, to attain the original sound the speakers were able to produce. Do the other options (Sonic/Dayton/others) improve the sound in anyway? Thanks for the loads of help so far!

Woofer measured at 2.5 Ohms, Mid 10.2 Ohms, Tweeter 11.5 Ohms. So it sounds like the tweeters need to be replaced?

The wires are soldered onto the speaker tabs. Would it suffice to unscrew the wire running to the crossover? Yes, it was set to Ohms and the leads were in the right sockets on the meter.

I opened one of the speakers to measure the impedance. All of the measurements were fluctuating and holding the test leads firmly on the tabs didn't seem to help. For the K33J's, the readings were 0.4 - 1.1 with the occasional 0.F. The K55V's were 0.6 - 1.0. The K77's were 0.5 - 1.0. Any suggestions on how to refinish the cabinets? The tops have some wear from (probably) being used as furniture.

Thanks for all of the advice and support. I by pulling the rear panels off and measuring the impedance. Maybe that will be a telling sign if anything is astray. Thanks again!

I listen to things from the 80s (think Tom Petty, U2, among other pop of the times), 90s (Soundgarden, Audioslave, Pearl Jam, etc.), 00s (Radiohead, Better than Ezra, etc.), and some heavier bands from the same time range. I also like classical guitar and occasionally listen to Jazz. Right now I'm wanting to build a audio system. I have a mid 00s Onkyo receiver/amp and Pioneer CD player. I'm also hoping to find good suggestions for best bang for buck sort of components, so any suggestions would be much appreciated. I don't necessarily feel the need for loud music, but often (currently) turn it up so I can hear a nice range of frequencies. My guess is if I could get good range, 75 dBa would be nice, but that's hard to get at the low end. The local hifi store closed down many years ago, so I don't know of many brands/models to reference my tastes to. Here's a nice photo..

While in high school in the 80's I got a personal factory tour at Klipsch in Hope and was able to see their sound test room, assembly areas, and got to talk with an electrical engineer. It was a great day! So, all these years later, I now have a beautiful pair of early Cornwall II's, but the sound isn't as impressive as I remember. From everything I can tell, everything inside the cabinets is original and I would like to do some upgrading. I'd like to get some advice on where to begin. I found the Crites website and have been pricing cross-overs and new drivers. What I don't know is benefit of going with the Type B or Type B-2 crossovers, and how decide on Sonic or Dayton capacitors. I'd also like to find out how to tell if the woofer, driver or tweeters need to be replaced. They visually appear to be in good shape.
