Yikes, now I want to keep them. Oh well, I can only protect so much of what I have. Thank you JeffW.

Hang on, I think I concluded this thread too soon. I got out some Mills 5ohm 1% resistors and they read 6.6ohm. So this proves the 5.7 reading is probably considerably higher than the actual dcr. ...

Thanks, that answers my question.

I have a pair of 2405 tweeters and in preparation for listing them for sale, I took the dcr reading, and was wondering if the low reading I got was indicative of any problem with them. On my cheap...

Rereading the paper on Linkowitz-Riley (LR), I missed that the shifting of the vertical propagation of sound, due to butterworth filter design was frequency dependent (see fig 1a).

I am considering building a new passive crossover, if there is a better design than the LX5 (else replace the caps and check the resistors). In reading a paper on the Linkowitz-Riley (LR) filter, I...

Thank you speakerdave, that's good news.

sidney, with new Apollo s7

Is that the proper reading for the resistance (the reading was taken with the signal leads detached)? I had them out to do the brake fluid treatment, so I figured I might as well check the...

I've been searching and reading here for over a man day now, and thank you all for the excellent reference material. It seems the woofer in my Apollos was used in about all the highest quality...

I picked up a pair of apollo c51 s7 speakers last week. They have nice cabinets, so the cabinets stay. I will replace the surrounds on the LE15A's myself. I presume some of the crossover...

Is it generally accepted that the 136a and 2235 woofers are superior to the LE15A?

I need to start a new thread on c51 modification. I will restate this question there, and see you all there,...

Thanks for the welcome, and I think Widget answered my question about date. There is a surround guy in the Phoenix area, and years ago he told me that he refuses to put foam surrounds on the back of...

I bought a pair of c51's with the LX5 crossover (pictures attached). I read that the older ones before ?1973 with alnico drivers were better. The serial numbers on the cabinets are 53154 & 53155. ...
