The reason we read the caps with our meters is that when you removed that hard substance covering them (you know the goop that's on everything, especially the screw heads for the binding posts?) there was nothing left of the markings that you'd expect to find!
Silly Advent and their "seat of the pants" approach. You'd think HK never expected us to be mucking about in his stuff over 30 years later - lol.

But, I don't think Advent actually purposely put 13s in the originals. 'Course, somebody along the line could have changed them like you said. Was there any value printed on the caps?
I suppose they could have drifted down to 13 from 16.
EDIT: You did NOT say "somebody" could have changed the caps. You said maybe Advent did. Read more carefully Doug. Hehe.

I'll refine and fill in your chronology, for future reference.
Henry Kloss was at Advent in 1975 when the first prototypes of the
stamped aluminum frame woofer were produced, and he approved them for production. That was early 1975. That year, Advent posted a loss,
and was recapitalized with new investors. Henry was thereafter
excluded from product determination decisions - that was late in
1975. Henry dissociated himself from the company after that to pursue
private video projects that led in 1977 to the founding of Kloss
Video Corp. It doesn't appear that quitting Advent Corp. was a
clean or sudden break. Andy Kotsatos, the designer of the Smaller
Advent, remained with the company another couple of years, and was
responsible for the design of the New Advent in 1976/7. The speaker
foundered among profligate competition.
Advent declared bankruptcy reorganization in Mar. 1981 and entered into an agreement to be acquired by Kloss Video. That fell through,
and the bankruptcy petition was amended to liquidation later that year. International Jensen was an autonomous unit of the Esmark Corp.
in 1982 when Jensen acquired the assets of Advent out of bankruptcy
The Jensen unit itself went bankrupt in 1995, and was acquired by Recoton. There is further history with Thomson Electronics and
Audiovox, but I'll elide that.
Essentially, 1981 marked the end of the heritage Advent lineage.
The fried-egg and ferro-fluid tweeters as well as the stamped frame woofer were dropped from production in 1981. (The Smaller Advent
had been discontinued some time before, in favor of the newer Advent/1, 2 & 3). All of the Advent badged speakers you named which
were sold in the 80's were wholly Jensen designed, and all the components were Jensen. They were all, to say the least, unremarkable
speakers. Jensen reincarnated the original Advent Large in 1994 as
the 25th Anniversary Limited Edition. It had the stamped frame woofer
of the (old) New Advent Large and a remanufactured black 1" soft-dome
square-magnet tweeter. It wasn't quite a match for Henry's cloth- annulus 1.75" KLH-6 style tweeter. Times had changed. and the speaker
had a short run.
The current Audiovox/Advent products bear no lineage with either the 80's Jensen speakers or the 70's Advent Corp. speakers, as you note.
They look like rebadged Recoton speakers to me.

I am adding some speakers to other rooms in the house using a Niles ss-6 speaker selector, and am wondering what the impedance of the Advent/1 speaker is? If the second set of speakers are selectable between 4 and 8 ohms which should I select to get the most from each pair of speakers? Thanks, the newbie

1) About the only thing on a woofer that truly seems to wear out is the surround (foam types that is) and i've never seen the cone itself break down except from outside causes like water damage or physical abuse (babies, pets, etc).
2) in 1997 when I ordered woofers from Advent for my 14 year old Advent "Babys" (I didn't know about refoaming kits back then) the woofers I received were *almost* the same though the cone material was not as felt-like as the originals.
I would be a little wary of "upgraded" woofers - a good speaker consists of a carefully integrated woofer/tweeter/crossover system and many times (in a woofers' case) a tweeter or especially the crossover is designed to make up for a specific deficiency in the woofer. So if a different woofer is used, the tweeter's/crossover's "settings" so to speak will not fit well and the speaker system's overall sound could be audibly affected.
If the surround is falling apart this could cause the cone to become misaligned and the voice coil (the unseen electrical part pushing the cone) could scrape against the internal magnet structure and permanently damage the coil, rendering the woofer useless & unrepairable.
The surround supports the outer edge of the cone and also provides a specific amount of compliance to allow the cone to move the desired distance back & forth with a specific amount of power. If the replacement surround is much too soft or much too stiff, bass output will be audibly affected.
4) I sold them for three years at Best Buy and I liked their sound & consider them to be worth repairing. And I agree that they are very attractive speakers. We sold many of them almost for that one reason alone.
Acoustic-suspension is very rare these days. Off the top of my head the only company that uses this design in most of their speakers and is *not* a tiny boutique manufacturer (i.e. relatively easy to find so you can audition them) AND has a great rep is NHT ("Now Hear This"):
Any company that uses yodeling on their front page can't be all bad! :^)
I would love to own a pair of their Classic Four floorstanders for a stereo-only/no subwoofer music system I am trying to put together.
This company was also affected by Recoton's mismanagement but they survived. Heres' a story about that which includes a link to a story about NHT's cool/quirky founder, Ken Kantor:

I am new to this forum - I just found it today. I searched the forum before I decided to post my question and I found a similar post from 2002 and it had not been answered, so I thought there would be no harm in posting a similar question in hopes that somewhere here could help me out with some information.
I have a pair of Advent Laureates that I purchased used in 1993 (serial # 3046514072). I really like these speakers because I think they sound lovely, though I'm hardly an expert. I do prefer acoustic suspension designs because I prefer bass response that is tight and accurate and not overwhelming, and I've always preferred two-way over three-way speaker configurations. These speakers have served well but about 10 years ago the rubber surround started separating from the cones (my limited research has revealed this to be a common problem). At that time, I was able to reattach the surrounds with glue. That worked for a couple of years but now the surround itself is not only detached but deteriorating. I've found refoam kits on ebay but wondered if they were close enough to factory specs as to not affect the quality of sound. Also, I wonder:
1) Should I expect these woofers to last this long? Am I wasting time to re-foam them? They seem like they are in fine condition otherwise but I'm no expert. How long can you expect a paper cone to last before the wear and tear of repeated sound reproduction cause the material itself to break down?
2) Is there a viable replacement woofer available? I've seen supposed "upgrades" available online with more durable and advanced materials but I'm wary that they may not be as well-suited to the cabinet design and crossover wiring as the originals.
3) Am I damaging the woofers to use them while the surrounds are in such condition? What is the exact function(s) of the surrounds? (forgive my ignorance).
4) I know these were manufactured after Henry Kloss left Advent and it had been acquired by Jensen, but is it the general consensus that these are decent speakers that are worth repairing and holding on to? They seem to me to be very well-made. I suspected that the front and top of the cabinets were a veneer over particle board and was surprised to find out today when I removed one of the woofers that the front board is indeed solid wood throughout. I've heard that dense particle board is probably a better material for speaker building, but I was impressed nonetheless that they used real wood. I think these speakers are beautiful, and hope I can get many more years of use out of them. I have a feeling I couldn't afford modern day replacements to match them in quality and styling. Is there even a two-way acoustic suspension home speaker being manufactured by anyone?
Sorry for a long-winded post, but any help and info. is much appreciated.

AR isn't *total* junk IMO, but bears no resemblance to its former self; according to their site Advent has been reduced to selling mobile video gear. :^( Those weird looking home speakers, supposedly rebadged speakers from a German manufacturer, AFAIK aren't on their site anymore.
As bad as sales for home audio components have been the past few years, as much as part of me hopes, I can't see Audiovox devoting any time/money to resurrecting even a respected name like Advent:
1) only people @35 years old and older will even know what Advent was all about;
2) the biggest group of listeners/buyers of music are people younger than @25;
and (here's the clincher)
3) from what I've seen, most people under 25 think anything larger than an iPod is "old-fashioned". I think if they were shown a typical console stereo system from the 1960s, they would need a jolt of oxygen to stay conscious: "Oh....my.....gawd......that thing is HUGE!!" :^)

PMJI, but I've found that wetting the dust caps first then applying vacuum cleaner suction straight from the hose in small steps sometimes works.
If it makes matters worse, sue someone else - lol

Silly Kent :^)
If they are the original Advents (with masonite woofer surround) they would not have a 13uF capacitor in them but rather, either 2 16 uFs or 1 16uf and 1 8uF. The first is the series capacitor for the tweeter and the second is the resistor bypass capacitor when the switch is in the extended position (the cap. lets more high frequency energy to the tweeter).
The 2 16 uF version is the earlier one used until about the middle of 1975 and then they switched to the 16/8 uF version. The resistor was also changed along the way from 4 ohms originally to 3 ohms sometime in the early seventies.
The 8uF cap. holds back more of the lower upper frequencies and the tweeter doesn't have to work as hard to reproduce these freqs. thus maybe smoothening out the response or perceived response.
Also, these are 2 way crossovers, not 3 (only 2 drivers).
All of my Advents have the later configuration, having all been built in 1975 or 1976 so I have never heard (except for in the early seventies-too long ago to remember) the earlier ones. I know Jerry (BoldEagle in the forums) likes the later version and has changed his to this config.
This harshness thing seems to be something that some claim bothers them and others don't really experience it. I, myself, don't think they sound harsh (unless the source is harsh).
I would check out the crossovers and make sure everything is OK there. There is a schematic available in the library section of this site and you can get the values of the components from it.
Ask more any time.
Doug/anybody: could you give us a rough range of ser. No's for the 16/16/3 types and the 16/8/3 types?
Carl's Custom Loudspeakers
Posted 03 July 2009 - 07:33 PM
I don't know exactly when the changeover was but maybe from serial number 150,000 and higher are 16/8/3?
My utilities are all later and all are 16/8/3. I believe this was the combination until the end of production of the original Advent Loudspeaker.
I have also noticed that there was a change on the black tape on the tweeters that may correspond to the electrical changes. Earlier tweeters have the tape going all the way across the masonite square and on the later ones, it stops and is cut off straight before it gets to the left edge.
I don't mean, of course, that the tweeters are different. Just that this may have been a simultaneaous change with the electrical changes.

I am looking for the specs for the Advent Mini speaker. There does not seem to be any information generally available. Thanks in advance for any help you can provide!
Posted 09 April 2010 - 06:17 PM
Unfortunately, I don't know anything about the minis.
