DonT Posted August 10, 2019 Report Share Posted August 10, 2019 I picked these up with a Sansui 1000X and all of it was REAL cheap. They are going to need some work but if they sound even close to my KLH Fives it will be worth it. Quote Link to comment Share on other sites More sharing options...
Doug G. Posted August 11, 2019 Report Share Posted August 11, 2019 Yup, get 'em fixed up so they sound new. Those are probably from 1973 or so, with those serial numbers. Doug Quote Link to comment Share on other sites More sharing options...

And it was the second day that they had the sale so everything was half price because they couldn't sell it the first day. Think about it? These sat there for a whole day at $10.00 for the pair and no one bought them. She was real happy I bought them because she didn't want to carry them yo the trash! She said she had a nice Bose system anyway ??? Quote Link to comment Share on other sites More sharing options...
DonT Posted August 14, 2019 Author Report Share Posted August 14, 2019 Parts are ordered and on the way. The cabinets on these have stains but I think they will clean up real nice. Quote Link to comment Share on other sites More sharing options...
ra.ra Posted August 14, 2019 Report Share Posted August 14, 2019 New foams and capacitors. Refreshed cabinets and grilles. You'll be very pleased. Quote Link to comment Share on other sites More sharing options...
Guido57 Posted August 15, 2019 Report Share Posted August 15, 2019 Nice find! Just for grins, could you post a picture of the crossovers when you open them up as there are several iterations of the crossovers in these speakers. Just curious.

DonT Posted August 15, 2019 Author Report Share Posted August 15, 2019 They are the first version with 2 16uf capacitors. Thanks to guys like Pete for the great Schematic. Quote Link to comment Share on other sites More sharing options...
DonT Posted August 15, 2019 Author Report Share Posted August 15, 2019 I think it is cool that the "Cheese Cloth" inside has the serial numbers on them as well. Quote Link to comment Share on other sites More sharing options...
DonT Posted August 17, 2019 Author Report Share Posted August 17, 2019 Well they are re-foamed. Now I just need the capacitors to get here. I hooked them up as is but they sound muddy compared to my KLH Fives. I am hoping the new Dayton caps change that. But for now I can start making them look better. I think they will clean up nicely.

ajfink Posted August 20, 2019 Report Share Posted August 20, 2019 The new capacitors will likely open them up! Let us know what you think. Quote Link to comment Share on other sites More sharing options...

The Advents look a LOT like the Fives but are not nearly as good IMHO. They're good, just not KLH Five good. I'm sure once you have the crossovers rebuilt they will sound very nice, but you won't be tempted to dump the Fives. But what a great find! Those AND the 'sui! Lots of people tell me they got rid of their vintage gear and bought a little Bose system that "sounds just as good." Then I invite them to listen to their favorite music through my AR=91s and they're left speechless ? Quote Link to comment Share on other sites More sharing options...

Then I invite them to listen to their favorite music through my AR=91s and they're left speechless ?" We had a friend and his wife over from out of state. She's a classical concert pianist and teacher. My friend and I were listening to jazz trio recording in my 1st floor "music room." The French doors were closed, but you could still hear in the rest of the house. My wife and his wife were in the kitchen, talking. All of a sudden, the door bursts open. It's my friend's wife. "Where is that piano? Who's playing? What......?" AR9's, powered by 400 distortion-free Parasound 2250 watts per side. Me, smiling. JKent is about, oh, 100% correct. People just don't know how absolutely stunning truly great audio is. Stunning. Jaw-dropping. Quote Link to comment Share on other sites More sharing options...

I had a newer set of Focals and after a week of listening and everyone telling me how much better they where than my KLH I sold them on ebay. They couldn't even compare to the KLH in my personal opinion. Quote Link to comment Share on other sites More sharing options...
ajfink Posted August 21, 2019 Report Share Posted August 21, 2019 By the by, have you considered converting these to the Rev.2, 16uf/8uf crossover versions? I did this to one of my pairs, and it's obviously an added obnoxious step, but thought (and this is a big ol' shrug from me) is that the newer revision was better.

Guido57 Posted August 21, 2019 Report Share Posted August 21, 2019 I think PeteB preferred Rev.2 and also pointed that the "dot" inductors could be problematic. Quote Link to comment Share on other sites More sharing options...

Yes, and when I rebuilt mine I went with Rev 2 and heavier inductors. BUT the original inductors have a higher DCR than the heavier ones and were part of the overall design and voicing. I would recommend sticking with original inductors. Kent Quote Link to comment Share on other sites More sharing options...
ligs Posted August 21, 2019 Report Share Posted August 21, 2019 Some Advent woofers have inverted rolls some have the regular out-facing rolls. What gives? Quote Link to comment Share on other sites More sharing options...
DonT Posted August 21, 2019 Author Report Share Posted August 21, 2019 I am going to keep these as close to original as possible. I like to preserve the history as well as function. If I don't like how they sound I can always pass them on to someone who does. Quote Link to comment Share on other sites More sharing options...
ligs Posted August 21, 2019 Report Share Posted August 21, 2019 Speaking of keeping these as close to the original as possible, It is interesting to note that the original Advent woofer has inverted foam roll as in this instruction video.

DonT Posted August 22, 2019 Author Report Share Posted August 22, 2019 I got the new caps in and WOW it made a huge difference! Now they sound like something Henry Kloss made. Still not quite as good as the KLH Fives but real close. All I can say is I LOVE yard sales! So far I have got the KLH Fives for $10.00 and now these for $5.00. After rebuilding both pairs I have about $130.00 in 2 pair of great speakers! Quote Link to comment Share on other sites More sharing options...

Doug G. Posted August 23, 2019 Report Share Posted August 23, 2019 Masonite ring woofers have inverted roll surrounds, all of them, or SHOULD have. The later all-metal woofers have standard mount with the roll poking out, or SHOULD have. The only way they get switched is if a subsequent owner changes them or a "professional" changes them.

Doug I hope no one is confused about mine because I installed them just like you said Doug. They are inverted. If it looks different to anyone it must be an optical illusion of my picture. Oh and I have been listening to these stacked on my KLH Fives and I LOVE them like that. It just sounds great! I think I might still keep my eye out for another pair of Fives though ?

Doug G. Posted August 28, 2019 Report Share Posted August 28, 2019 Yes, the optical illusion is common with the Masonite woofers where they look like the rolls are poking out when they are not. There are subtle clues to tell. Doug Quote Link to comment Share on other sites More sharing options...
Frank Braswell Posted December 2, 2021 Report Share Posted December 2, 2021 after watching the video and your comments you have answered my question about the purpose of the masonite ring on the OLA woofer. now i feel confident about doing this myself. thanks for sharing your knowledge.
