Older Advent Floor Standing Speakers...

They're pretty good as you say, one of my friends got some from his grandparents. They do have an impressive bass, not as quick or clean as some newer speakers but good fun to listen to. The original orange tweeters on his went bad, but he got a pair of replacements, metal dome type I think, which work fine (I haven't listened to those much). I think the midrange on these speakers is a bit hoarse or hollow sounding, which is fine but maybe the crossover could be improved to fix it. Heck my speakers have that kind of problem in the midrange too and I'm plenty happy with them.

Of course Advent used to be respected (in the 1970s?), I wish I knew what happened to them. I'll ask my friend if he knows.

Matt -
The original Large Advent was really a classic in its time - and that's probably what you have? Depending on which model you actually have (shiny finish like that eBay link or original walnut, etc.) they are fairly big, solid, bookshelf speakers (honestly - that's how they were sold way back then) and they could last forever. The woofers usually need surrounds replaced (yup, mine did, too) but other than that the vast majority last and last. There were all sorts of "polite discussions" about whether 2- or 3-way systems & crossovers were superior and those Advents were often one of the main "exhibit A's" for the 2-way camp.

As much as technology marches forward, there will still be examples like those Advents of how much things really haven't changed all that much. Heck - the cabinets on those things are probably more substantial and solid than 90+% of anything you could buy new today. Advent was a very respectable company when those things were first sold.

Advent was another company in which Henry Kloss (the K in KLH) was a lot of the brain power. Something curious. Advent is the legal name of a new business before a real name is given. In this case, they just kept the name. Perhaps a tribute to new thinking.

The original Advent was a very handsome, substantial "book shelf" speaker, though at about 25 inches high could be used on the floor. I agree with Michael on the bass. It was quite extended, but not quite as quick or clean as some others of that time. As I recall, the woofer cone was closer to a 10 inch (or smaller) in a 12 inch spider, but made up for it with a very flexible foam surround. This was also significant as the Advent was a sealed box, not vented. By making the surround pliant, with a free air resonance of maybe 15 Hz, you were able to generate a lot of bass. These sealed boxes were known as "acoustic suspension".

The other major innovation was the tweeter/midrange. The Advent tweeter was made of one piece of treated paper with a dome in the center and a wide "surround". What this meant was that the crossover from the woofer to the tweeter could take place at a much lower frequency.

The ideal speaker would be a single point source, i.e., one driver for the whole spectrum. The Advent made the most of a 2-way design.

The Advents (and then later the Smaller Advent) were very popular in the 70's: competing both with KLH and Acoustic Research. Henry Kloss went on to bigger things including perhaps the first front projector system of moderate price.

The one weakness of the Advents was the foam woofer surround. As other companies have found out, foam is good when it is new but deteriorates badly over time, turning to dust.

I know a guy who still has his original Advents. He too had to replace the woofers.

In the 70's the Advents were the speaker to beat.

Hang on to 'em.

Artie

So that could explain why I remember the midrange sounding hoarse, if the crossover is at something like 1KHz. Most 1" dome tweeters are hard pressed to go below 2KHz without significant distortion.

Michael

Yes, most 1 inch metal domes can't handle down to 1,000 Hz.

I think Advent still made some very respectable speakers well into the early 90s....the Baby Advents, the Graduate, the Prodigy, etc.... By that time, Advent also updated and reissued a new version of the Large Advent. During the 80s and the 90s, Advent was one of the brands under Recoton Corp.; Recoton also owns Acoustic Research (AR) and NHT. Last year, NHT was sold to Rockford. Shortly after that, Recoton went belly-up. AR, the speaker division, was purchased by Audiovox; the cable or accessories division went to Gemini Industries. Advent? Don't know.

I hope someone revive this once respected name in loudspeakers.

I'm still using my vintage Large Advents that I bought in 1971 for $250/pair in walnut. I've had to replace the woofer surrounds twice in that time. The woofers are 6 1/2 in. in a twelve in. spider. The crossover to the tweeter was 1500 Hz. The reissued design that came out a few years ago used a completely different woofer. To me they have always sounded like they were playing though a veil. One popular approach in the seventies was stacked Advents - two per side. I'll never get rid of them.

All this talk of "respectable" — good grief, guys, the original Larger Advent Speaker was a freaking classic, one of the best acoustic-suspension bookshelf speaker systems on the market in the mid-seventies.

One of the most impressive affordable setups audiophiles concocted circa 1975 was the so-called "Double Advent System." Basically, two Larger Advents per side in a two-channel music system. One such system I heard at the time featured Double Advents being run by a Crown DC-300 power amp being fed by a Crown IC-150 preamp.

The openness and transparency of the sound was more akin to a good electrostatic, albeit one with good "oomph" in the bass, along with impressive dynamic range — all courtesy of dynamic drivers.

Also impressive was the second model of the era, the Smaller Advent Speaker.

Still running my "New Advent Large" circa 1978 in the upstairs rig. The woofers have been refoamed once, and still look good today.

The "tweeter" is actually a combination mid-range and tweeter, with a doughnut shaped outer surface, and a parabolic inner dome (almost like a Vifa ring tweeter).

The large radiating surface area of this driver, combined with ferrofluid cooling (big back then), easily allowed a 1,500 Hz xo. This driver exhibits an effortless midrange (reminds me of a horn at times), bringing snap and life to snare drum, brass, and vocals that even today is still hard to match.

The Advents far fall short of today's offerings in terms of imaging, depth of soundstage, and inner detail. But for casual listening, they still bring a smile with excellent overall balance and that famous Advent bass.

I bought a pair of powered Advents in 1979 ... They were bi-amped with some very powerful 80 watt amps... and were an amazing loudspeaker...

The Stacked Advents with the right amp was also a wonderful system... Sold a lot of those in the late 70's...

good memories... now if somone wants to talk the Old Electrovoice Interface series...

Aren't the woofers actually somewhere between 8 and 10 inches in size?

Yes, it's an odd size, like 9" nominal, IIRC. They offer really decent SPL (for their time), and get down to around 30 Hz strong.

Craig:

I recall the old Electro-Voice Interface speakers. E-V introduced them at the hi-fi show in NYC (1972?). I clearly recall the marketing effort--small box, yet big bass and wide dynamic range. The Interface used some then-untapped Thiel (not Thiel, the manufacturer) theories, if I recall correctly. I'm sure I still have the E-V brochure buried in a box with other product literature from the period.

They sounded stunning at the show, but I never once saw them again anywhere.

I would love to hear more about them, the good and the bad.

advents are wonderful speakers! i bought a pair, new, in 1978. refoamed about 10 years ago. last year i bought a bunch of parts on ebay, and i now have a pair of doubles in the front, along with a double for the center channel. sides and rear are r-s minimus 7s, which sound very similar to the advents, except no deep bass. rears are going to be custom-made smaller advents, once i get the new bookcases installed in the back of the room.

i picked up a pair in walnut for 50 bux last year, and foamed them for 25. well worth 75 bux!!!

enjoy them, they are hard to beat!

btw, mine were rated at 15 watts MINIMUM, no maximum in home use with musical material. you might try a 3 amp fuse in series with the input lead, per advents recommendation.

FYI, to all those thinking of using these classic speakers in a home-theater system: Remember, they are not magnetically shielded. That wasn't even an issue when the Advents were so popular.

And all along I was thinking I am the only one still using the Radio Shack Minimus 7s....

Alex - Yes, E-V was an early adopter of using the Theile-Small math in their designs. The original Interface:A came with an outboard EQ... I found a pair on Ebay a couple of years ago and grabbed them... and they dusted the JBL 100's...

The Interface D's were a really impressive loudspeaker... Flat Bass into the mid twenties... great sound...

When I was a kid, my cousin had a fantastic pair of 3 way Advents with a 10" woofer, dome mid, and dome tweeter. I fell in love with their sound.

Recently I had a chance to look at them. They're the Maestro, which is a model or 2 above the Legacy line. The foam surrounds are shot and I'm going to be replacing them for her. I can't wait to fix those woofers so I can take another listen to those beauties!

danny tse: i have bought 4 pairs of m-7s over the years. one pair is serving as the main speakers in my parents 40 foot travel trailer. the other 3 pairs are doing just fine as surrounds in my ht setup. they sound great!

at one point, the m-7s were serving as my only speakers in my first surround sound/video system, with the sub under the house, in the crawl space, firing up at the floor. sounded quite good, but they really couldnt put out the dbs i wanted. so, back to the advents!

Andy,

I still have a pair of Minimus 7, which I used as surround speakers in my Dolby Surround setup (this was before Dolby Pro-Logic was invented). I am going to take them out again and mate a powered-sub with them and use them in a bedroom system. These things are probably extremely power hungry.

i would imagine if you used a modern a/v amp and crossed them at 80hz they would work better than the way i had them set up. my only option was to run them full range, with a passive low-pass filter (BIG coil) for the sub. i was feeding about 12 watts to the sub, and it still rocked the house! 75 watts to the m-7s.

oh yeah..... once i equalized the system with a 10 band eq and a pink noise generator. flat all the way across. then i noticed i had forgotten to turn on the sub amp! good little speakers! really limits the max spl that way though.

I also was running a set of stacked Large Advents. In this case I'm pretty sure that the fuse recommendation was a one amp fuse: not three. In fact, my best memory was a .75 amp fuse that I had rounded up to one.

Also, use a sub. After dropping the fuses out of the lines out of carelessness, I blew a woofer watching Jurassic park. They'll take a lot, but they are not unbreakable.

Hi:  I am an original owner of the Large Advents since back around 1970, and have such fond memorys of them.  I blew a woofer over a decade later but stashed them in the basement rather than part with them...I knew they were special.  I then bought a used pair of speakers from Japan.  They were huge and absolutly unlistenable.  I bought them without a listen figuring how bad can they be and the risk was acceptable.  Bad idea.  They were several hundred dollars and less than year later I threw them out and bought a new pair of KEF C95 floor standing speakers, which I like, but they never really blew me away.  For a grand in the mid to late 80's, I felt just a bit wanting with them. They also required two replacement tweaters since I bought them.   I recently tripped on my  balck lab and actually had to tackle one of the KEF's to break my fall.  It no longer plays, and I cannot find the fault.  So I am on a mission for some good speakers.  I see I can get an execellent pair of B&W 630's for more or less $500. maybe plus shipping.  I now see mint large advents could be had for less than 300 delivered.  Since I have backup parts I might do this, but I really want the choice to be on the quaility of the sound.  I recently bought a mono block tubed intergrated amp, which is as good as it is getting for me and I love it  So whats the consences.....go retro or contempoary?  Would I be giving up appreciable sound quaility for retro?  They would also take up a bit more space.  Appreciate the feedback.

This thread is kind of old, but thought I'd respond anyway.  Larry, sorry about your fall over the dog, but maybe that was a good thing.  I've owned a pair of Dalquist DQ-10's since they were new in 1977, which was about the last year they made them--they sold for $1000/pair.   They were and still are regarded as one of the best speakers ever made, but a finicky and very power hungry.  Funny thing is they had the same woofer in them as the original Advents.  I had the woofers refoamed about 10 years ago by MILLERSOUND, in PA. The guy who runs the place, Bill Legall, did an excellent job, was very quick and inexpensive- cost about $50/speaker for an upgraded cone.  The speakers came back and sounded "better than new" with much improved bass, which was a shortcoming of the speaker.  I just acquired a pair of original Advents from a neighbor.  The woofer cones are totally trashed- hardly any foam in them at all.  I called up Millersound (on internet www.millersound.net) and found him still in business and he was, I spoke to Bill directly.  So $35 each to refoam and $85 each for a "works upgrade"  which he said will blow me away with the improvement.  Turns out Bill also owns a pair of Advents so he knows the speaker intimately.  So I recommend you pull out those old Advents and get them fixed up.  I'm opting for the "works" so I'll repost with the results, but that will be a while b/c I'm slow.

 

Regarding good speakers out there.  I've listened to a lot of speakers over the years, and am not impressed with very many.  The industry has gotten crazy with super expensive stuff, and actual sound quality has taken a back seat to "hype".  There have only been a few that could compare to the Dalquist when properly set up, and this includes speakers that cost up to $75,000 (which is kind of ridiculous I think).   However, one speaker that I was very impressed with recently was a QUAD model 22L2, Performance Series speaker.  This is a floor standing tower type speaker with 2 woofers & 1 tweeter .  The sound was very neutral, extremely musical and good solid bass.  They sell for about $1700 pair.   I liked them better than several speakers costing $15k +. They also have some smaller, similar mini-monitors which are cheaper.  You can check them out on www.arisaudio.com.  GOOD LUCK!  

I just unpacked a pair of wireless black Advent speakers from Recoton. I think we bought them in the 80s or 90s. Would any of you know how I can connect them to my new Macbook Pro? My recollection is that the signal went out from the CD or VCR player and we tuned it in on the speakers. I don't recall what the signal type was. I suppose it was radio. Does anyone have a suggestion?
Thanks,
Rita
