  1. KLH Model Thirty-Two Loudspeaker

    I briefly had a single 32 speaker, and I compared it to one of my Model 31's and I can say that the 32's tweeter, pink fiberglass front and all, was very bright. The 31 was more balanced, and without the fiberglass over the tweeter. Based on this audible difference I thought they were different tweeters, but then it could just be a difference in the crossovers. They were definitely wired differently. The Thirty-One has a single coil, with a 4uF capacitor and a 4-ohm resistor. I think I remember the Thirty-two having two coils and one capacitor.
  2. Restoring KLH Model Thirty-One Speakers

    Thanks for the tip. I pushed in the cones like you said, and they pop right back out. I found a Youtube video of someone performing this test, so now I know what it should look like. Your Twenty-Seven looks great! I can't find a photo of one in decent shape... they are either all banged up, missing the sides, or have missing and/or substitute knobs. Mine was (and still is) immaculate... like the previous owner kept it in the box for decades. There isn't even any dust on the inside, and that is remarkable given the very porous grill that is the whole top panel! Here's my photo album of the whole thing, front to back: https://flic.kr/s/aHskuP1BoR
  3. Restoring KLH Model Thirty-One Speakers

    Thank you everyone here at The Classic Speaker Pages forums. I could not have done this without you. What a wealth of info you have here! Restoring these KLH Model Thirty-Ones has been a rewarding experience, to say the least. I started out with very good looking exteriors, but non-funcioning tweeters and non-KLH woofers with disintegrating foam shrouds. I think they were also tripping a safety-circuit on the Pioneer's amp, as the sound was cutting out, then in after a few minutes of listening. Yeouch! Didn't leave it on long enough to track that one down. I obtained two original woofers and replaced the capacitors and resistors (one in each cabinet). No soldering, just wire nut connections. I simply duplicated what was there. Getting two woofers from two different sources, I was skeptical they would sound similar, but they are well matched. I also bought some sealer for the cloth surrounds, thinking I would need to re-apply. Turns out the sealant on them was still tacky, so I didn't use it. All I have to compare them to are my Klipsch R-15m 85w bookshelf speakers, as they are what I normally run with the big Pioneer system (SX-850 receiver, PL-71 TT). I don't know the rated wattage of the KLH 31's. Although I know they are very entry-level for the KLH line, I really don't know what brands and models ("class") they should be compared to. The first thing I listened to was "All Through The Night" by Cindy Lauper. (Don't judge me! It's just what was on the radio when I turned it on!) Turns out, it is a pretty good test song as there is a wide dynamic range, and lots of stereo action (little keyboard action on the left.... drum or other effect on the right...) After that it was "Beat It" by Michael Jackson. Still impressed with my new speakers. Next, I put on some vinyl: the Brothers In Arms album by Dire Straits. Side one, beginning to end. All three listening tests were of similar results: The KLH Model Thirty-One's are a very good speaker, worthy of restoration. It's my perception that they are a warm but precise speaker. Typical to what I've been reading, the bass is just a little bit light. It's all there... just that I hear it more than feel it. It's not an annoyance, just an observance. The mids and highs are pleasingly well-balanced. I was most impressed with the soundstage, second only to very detailed mids, as the music actually felt three-dimentional. I wasn't just hearing the music, I was experiencing it. It was materialized there in the space in front of me, between the speakers. So there you have it. My restoration and review of these budget KLH Model Thirty-One speakers. They sound great and were worth the time and effort I put into them. I will be pairing them with my KLH Model Twenty-Seven stereo receiver, and Philips GA-427 turntable, which is my next restore job.
  4. Restoring KLH Model Thirty-One Speakers

    As you stated, Kent, I did not notice any difference between woofers, significant nor other. I finally received the resistors and capacitors from PartsExpress yesterday, so after work last night I swapped those in, then mounted the stock woofers and whamm! what a beautiful sound! I am more than pleased with these Model Thirty-Ones. They sound... smooth, like a Shure V15 phono cartridge. The tweeters are the dominant component here. There is more mid-tone coming from them than there is from the woofers, from what I hear, and they sound sooo good. As luck would have it, immediately after my previous post I spotted a new posting on the auction site. It was for a single Model 32 speaker, working great, and for $20.00. Got it. It arrived this morning. I swapped the mystery woofer with this 32's woofer (I know for sure these are the exact same woofers) and I now have a complete, correct pair of KLH Model 31 speakers, serviced and looking and sounding great. Posted the donor Model 32 on the auction site, specifying the substituted woofer, for $25.00 or B.O.
  5. Restoring KLH Model Thirty-One Speakers

    I now have both 8-inch 8-ohm KLH woofers. The two are almost identical. As I said before, one is definitely out of a Model 31... the other is a mystery, with a date stamped in blue ink: "JAN 27 1969" Without seeing the voice coils, the only differences between these two are the voice coil spider. The Model Thirty-One has one more ring that the older woofer has, and the rings are shaped slightly different. Hopefully that doesn't mean a completely different voice coil. Still, it'll be better than nothing. I don't know what purpose the grid-pattern on the cone face serves, but aside from that and the spider underneath, these look identical. I'm still waiting for electrical components from PartsExpress so no sound test yet, but if they don't sound the same I'll still use it until I find another Model Thirty-One or Thirty-Two woofer.
  6. Restoring KLH Model Thirty-One Speakers

    So, all the items needed for the restore project are ordered: * Two 8-inch, 8-ohm KLH vintage woofers. One was specified as being out of a KLH Thirty-One and the other didn't specify any model, but except for missing the grid-pattern of sealant on the cone face, it looks identical to the other one. If it's not an exact match, it's still better than nothing. * Capacitor (2): Dayton Audio PMPC-4.0 4.0uF 250V * Resistor (2): Dayton Audio DNR-4.0 4 ohm 10W * Cloth-surround sealant for vintage acoustic suspension speakers. The cabinets and grills are in beautiful condition, and need no work what-so-ever. I know these are the absolute runt of the KLH litter, but I hear they still sound great in a small setting, with a very smooth, unobtrusive sound. They are what came along at the right time, and at that time seemed to need very little work. They will be perfect for what I will use them for. I even have stands that, aside from being a bit too high, are perfect for their size. I need to cut them down a bit to add weight to the bases anyway.
  7. Restoring KLH Model Thirty-One Speakers

    There is no manufacturer name on them (TI is all) but they are black with red ends and red leads... made in Mexico.
  8. Restoring KLH Model Thirty-One Speakers

    I have another question: If these are 8-ohm impedance speakers, then why is there a 4-ohm resistor in each speaker?
  9. Restoring KLH Model Thirty-One Speakers

    Thanks for responding! There were two 8" x 8-ohm KLH woofers posted there by two different sellers; Last night I bought that one in your photo, and after reading this I just bought the other one. The tweeters look original, though they didn't seem to be working. The capacitor and the other component in the wiring (sorry... I'm still learning!) both look new, and there is no physical signs of damage like on the woofers, so I'm hoping that will get sorted out when I install the original woofers and figure out the wiring.
  10. I am restoring a pair of Model Thirty-One speakers and discovered right away that the woofers don't look original. Can someone please tell me if this woofer is possibly the original for this KLH Model Thirty-One? I don't believe it is, but I'm new to vintage speakers and know manufacturers sometimes substitute components for various reasons. Both speakers have this same unmarked woofer. No name... no number... nothing printed or stamped on them anywhere. They look nothing like what I have seen.
  11. Hello! I am new here. I have been into vintage audio for about 4 years, and in that time I have assembled three functioning turntable systems, two of which are in regular use. I am currently putting together another system. I have owned a KLH Model Twenty-Seven stereo receiver for a couple years, and wanted to find a turntable with a very distinctive appearance to go with the Twenty-Seven's unique styling, and settled on a Philips GA-427. However, I have two parts units I am using to make one complete TT and will be re-finishing the wood plinth to match the Twenty-Seven. Work in progress. For this setup, I have also recently aquired a pair of KLH Model Thirty-One speakers that I now know I paid too much for, as the woofers need replacing. But, life goes on. I have already located one original 8" woofer and am currently awaiting delivery. I once swore I would never buy vintage speakers, (said the same about turntables, too!) but now here I am with a pair of KLH Model Thirty-One's that I am excited about reviving. My, how things change... System #1: Pioneer SX-850 stereo receiver, Pioneer PL-71 turntable / Shure V15 Type III cart with authentic Shure stylus VN35e, Klipsch R-15m speakers. System #2: Pioneer SX-424 stereo receiver, Dual 621 turntable / Shure V15 Type IV cart with Russell EVG aftermarket stylus VN45e, Denon DVD-2800 (used as CD player), Klipsch R-14m speakers. System #3: (in storage and for sale) Onkyo A-8150 stereo integrated amplifier, Philips AF-677 turntable / Philips GP 401 II "Super M" cartridge w/ JICO aftermarket stylus, Sony SS-B1000 speakers.
