gigantic Posted September 1, 2022 Author Share Posted September 1, 2022 I took them to my workshop today and opened them up: K77 tweeters, K-55 Squawkers: & K-22K woofers, although these will be replaced with the same spec woofers that I'm getting from @dtr20 1 Quote Link to comment Share on other sites More sharing options...
gigantic Posted September 1, 2022 Author Share Posted September 1, 2022 The tweeters had a fair amount of cadmium oxide buildup on them: They cleaned up nicely with some denatured alcohol: The crossover network looks relatively clean: it's a type C, as expected: those caps seem sketchy...

gigantic Posted September 1, 2022 Author Share Posted September 1, 2022 finally, for today, I did an preliminary pass of filler for the staple holes, gouges, scratches dings and chips, then applied sanding sealer and grain filler. Tomorrow, they'll get a coat of primer and another pass of spot putty to fill any dings still visible after priming. 4 Quote Link to comment Share on other sites More sharing options...
gigantic Posted September 1, 2022 Author Share Posted September 1, 2022 back to the crossovers: it's my understanding that the Type C crossovers were matched to the K-22 & K-22-E speakers, which were 16 Ohm. My recollection of these speakers is that they sounded clear, but they also sounded quite dull, with very little bass. I realize that low-end thump isn't the strong point of these speakers, but given the 8ohm woofers, would it make sense to change the capacitor values to Type E?

Typically, they had 16Ω K-22 or K-22E woofers, although this seems to have changed later in the run, to 8Ω K-22-K & K-22-R woofers, along with a change to the type E network at some point with the H1.

I realize that low-end thump isn't the strong point of these speakers, but given the 8ohm woofers, would it make sense to change the capacitor values to Type E? so this keeps getting misdirected: My late build H700s are indistinguishable from H1 speakers, which have 8 ohm Alnico K-22-K woofers, except for the Type C network, which was configured around 16 ohm K-22 & K-22-E woofers. While I will most certainly test them with the OEM network, I'm going to assume that the original OIP capacitors have decayed and are no longer in original spec. Given that replacing the caps with modern construction resistors of equal value wouldn't be the same as the original network and that this specific configuration of tweeter, squawker and woofer were ultimately updated by PWK to the Type E with the flipped polarity for the mid and tweeter, would it be best for the performance of the speaker, used in a 2 channel system, as well as the primary drivers in a 7.1 surround system, to use the type E network and upgrade the capacitors and inductors to that spec? *I have no interest in selling/flipping them and I would posit that the "improvements" that I've made to the cabinets, while aesthetically better than they were before I began and arguably better than new, have nullified any resale value these might have had, which given their condition, was negligible, except for parts.
