yea someone tried to bid them up, but I still won for a decent price. they have arrived and are in working shape as far as I can tell I took the tweeter out of the one so I can get better access to twist new capacitor in. I am fortunate to live in an area with a lot of electronic manufacturing so my city has not 1 but 3 electronic stores.. I was able to get all the pieces needed for under $5.00 locally (includes twist cap wire things and NY tax, not bad at all and instant, maybe I should have got the crimp joiner things now that I'm looking at it). There is some white powder caked onto the back of the tweeter, I can't tell what it is. There was some thin foam/Styrofoam pieces to protect the tweeter from the wood cab and top paper piece thing.. interesting. I wiped the box out with bleach and paper towel.. it still smells musty.. any other ideas? Also I need help rewiring them.. since I had no woofer to take out and look at for reference. (now all of a sudden all of the pics are vertical aligned on this post... so time to cramp your neck) so.. There is a big round thing and it looks like it is wrapped in copper wire. There are 2 bare copper wires coming out of it. 1 goes to positive incoming line which then goes to a capacitor and then to the tweeter. So I'm guessing the incoming positive signal comes in and meets the 1st bare copper wire and that brings the signal to the big wound up thing and then the 2nd bare copper wire goes to the positive on the woofer? (I'm guessing here), then the same signal is also sent through the capacitor to the tweeter positive. The ground is coming in and twisted to the resistor and then after the resistor it is twisted to go up to the tweeter negative ground terminal. should this bundle before the resistor go to the woofer negative ground or should the incoming black wire go to the resistor 1st then the woofer and then up to the tweeter? I find it odd that it is already capped off. I did not do this. I just cut out the woofers and mailed then out as far as I remember. It's possible but unlikely I put these black wire caps in here but I do plan to use them and maybe return the ones I bought at the store. That said, I only have about an inch (less than an inch) of spare wire coming out of the woofers I got on ebay to connect them. This may or may not be enough to put one of those caps to. Can I just twist it together and leave it as is? What is the danger in that, if any? thanks for any info on wiring.

yes thank you for making that! I think someone pointed me to that recently ?

ah ok. yea thanks.

hi! thanks for the info. I didn't see any model 20 10" woofer listed as 8" on ebay. do you mean this one?: https://www.ebay.com/itm/Nice-Pair-KLH-Model-20-Woofers-Very-Original/333140637789?hash=item4d90bab85d:g:PH0AAOSwe9VcTtH4 I took pictures but then realized you probably meant the back plate stuff where the speaker wires from the amp go to.? I was not 100% sure what you meant about cross overs. I know what they do and the function but have never seen or looked at one. ha. once I get a better pair of gloves and some proper sized bags, I should be able to see everything I'm guessing. I'm not against searching for a 8" KLH woofer set, I'm also not against buying a new (non KLH) woofer either. As I remember they were a little muddy and lacked some bass. maybe a recap would help that? I also noticed a little black hexagon stamp on the back, I can faintly make out a KLH and a 16? 19? I dunno I never noticed it before, ever see one? and this webpage seems to auto rotate my pics.. which is not good because I already rotated them correctly. Appears it is set to have the longest side = horizontal axis automatically I guess, which for some of my pics is not correct, bear with the neck turning. Also the white cloths are there. thanks again

thanks! cool pics. yep 2 way speaker box. 8 inch woofer (but really 8.25 diameter where the screws go) and a 7.125 opening for the woofer itself. 2.5" tweeter, I didn't measure but sounds about right. Mine have the lighter color cloth for the grill (like the model 17 there) not the dark brown pictured. I find it interesting that it is half an inch shorter than the 32, but wider and deeper. Would that give more bass? it is a sealed box.

I saw a thread on here about a model 31 restoration, which gave me hope. long story in 1 paragraph on these: I bought these forever ago like in 1998-1999 as a teen at a thrift store for $20 that included a kenwood turntable. (wish I could find deals like that again). I put them up for sale years later (on ebay ugh) but the winning bidder only wanted the woofers (odd to me at the time but ok). Double my money back and still had like 90% of the speaker, cool. I had purchased (better at the time) decent pioneer 3 ways. tall. big. loud etc. that came with a block party 80's LXI amp that I also pulled out and want to use today.. (don't judge just yet, it's made in japan, 190 watts and has built in 5 eq slider frequencies, that if i remember correctly worked well). The poor Klh sat in my room and then a basement for about the last 10 years. I pulled them out and have had them airing out on the sun porch I have in my apt. Cosmetic: they have gotten better but still smell musty. Any tips on how to get this out? and is that fiberglass in there? I poked my hand around and don't see any wires coming out for the speaker just yet, but now my hand feels like it's getting stabbed by a needle every so often.. ha. The grills are in decent shape but could probably use a cleaning, any recommended sprays or process for this? Woolite spray cleaner? Out side cabinets are presentable. I'd rather the speakers sound good then look good, if I had to choose one or the other. Important spec questions: So I need to order some odd size KLH 8" woofer (really 8.25 outside diameter measured not 8..) and the inside hole is 7.125" not 7".. I actually found these: https://www.parts-express.com/goldwood-gw-8pc-8-8-delmar-series-heavy-duty-woofer-8-ohm--290-314 they are power hungry but they are the right size and ohm and frequency range I want. So I 'd like to order those. the tweeters in the KLH should be fine they worked last I had them running. I noticed that it is recommended to replace the resistors and capacitors? that thread used: Capacitor (2): Dayton Audio PMPC-4.0 4.0uF 250V and Resistor (2): Dayton Audio DNR-4.0 4 ohm 10W would those work for me? he had vintage klh woofers to put in, I do not, I'd like to buy the ones above (unless someone has a better similar priced option?) also what is the difference between "precision audio capacitor": https://www.parts-express.com/dayton-audio-pmpc-40-40uf-250v-precision-audio-capacitor--027-226?utm_source=google&utm_medium=cpc&utm_campaign=pla&gclid=EAIaIQobChMIn76I04fX4wIVBJ6fCh2xdAr3EAQYASABEgJk4PD_BwE and polypropylene capacitor: https://www.parts-express.com/dayton-audio-dmpc-40-40uf-250v-polypropylene-capacitor--027-421?utm_source=google&utm_medium=cpc&utm_campaign=pla&gclid=EAIaIQobChMIn76I04fX4wIVBJ6fCh2xdAr3EAQYAiABEgLeWvD_BwE this is the resistor that I would get: https://www.parts-express.com/dayton-audio-dnr-56-56-ohm-10w-precision-audio-grade-resistor--004-5.6?utm_source=google&utm_medium=cpc&utm_campaign=pla&gclid=EAIaIQobChMI2JDmsrTY4wIVBJ-fCh0YOQ3OEAQYBCABEgK3MvD_BwE would I just cut out the old and solder in the new? soldering inside a fiberglass speaker box might be above me. I've only soldered a few wires before on an open guitar.. I don't even have the iron anymore I don't think. There is (amazingly) a local audio electronic repair place, I could ask them, let them do it, or watch a you tube video. I don't know much about electronics, but I do know different resistors and capacitors work better and worse depending on what you have and want to get, so if anyone out there knows if my choices are good or bad please let me know. also if you have any suggestions on a better capacitor or resistor let me know (and maybe explain why if you have the time, thanks in advance). I will post some pics if you want? Thank you ! for any info or help.

shame that stereophile didn't post any pictures, or did I miss them?

even in 2007, (original posting date) I don't think it had to be zipped. unless poster had dial up? but I used to post 4-5 meg files via dial up in like 20-25 min. in 2006. anyway, if anyone has unzipped version thank you! and much appreciated !

why is that excel file.. a zip file?? is it 1995? even if it was 1995, it can't be more than 5 megs?? does anyone have an unzipped version they can post here? or link to? I do not have winzip or any "unzip" apps. / programs. thank you! looking for info on elusive KLH model 31 thank you!
