Oh yes--DYNACO speakers-those were real sleepers among Hi-Fi folks-sort of forgotten but excellent speakers.And they worked well with their amps-SS or tube.There is a man here at the tranmsitter site that loves Crown amps and JBL speakers-He rebuilds his own JBL speakers.He plays them loud so on occasion has to rebuild his.When I worked at the commercial radio station in Wash DC area JBL and Electrovoice speakers were common staples in radio stations for program monitor speakers-be it at the studio or transmitter site.Was lucky to have a large music shop in the Area-Veneman music-they rebuilt other speakers besides JBL.I would send the stations blown JBL's to them and for less than half the price of a new driver-would get the old one rebuilt-like the same idea as transmitter tubes.And would bet most speakers rebuilt today are for "G" fiddle amps and other musical instrument applications.Makes me think of one morning when I showed up for my early morning shift at the stations transmitter plant.Bad thunderstorm during the night.The site is unmanned at night at the time.I found the JBL speaker grill covers laying the floor-and thought"What the??Why are those on the floor?"then looked up and found woofer cones hanging down only by their leads.Sorrounds completely ripped.Storm blew the amps-the output stages shorted-and the DC blew the speakers.Myer Emco fixed the amps and Veneman music rebuilt the woofers.Used an older pair of ElectroVoice monitor speakers along with a an old Op-Amps Lab amp.The Op-Amps amps came in kits and were kinda fun to build.Marketed to professional places like radio/TV stations and pro audio-the amps would do fine for Hi-Fi use.An Op-Amp IC drove the driver and output transistoers in the amp-they worked quite well.Very serviceable.Easier to fix than Crowns.The Crowns were selected by management because of the name-they are good amps-The Op-Amps were more easily fixed-but not recognized by management "vistors" they would tour thru the studio or transmitter site.In the above incident--the speakers were fused---but the fuses didn't blow!!!Weird!!!!Other times they have when someone tried to play the speakers too loud.This was good with the DJ's.They were good at blowing midrange drivers and tweeters.Something else funny about the blown speakers-those were for the FM monitor amps.The AM speakers wewre untouched!One channel of the Crown amp ran two JBL monitor sepakers-one behind the tranmsitters so you can hear the program if you are working there-other in the front.The second channel of that amp fed to cheap monitor speakers at the tower bases-that was so you could monitor the program and mute the audio for a few seconds to get tower base current readings.Lightening can do STRANGE THINGS!!!
 
dynaudio

i have used dynaudio speaker drivers made in denmark(quite possibly related to or a rename of the "dynaco"speakers mentioned upthread)Indeed very impressive speakers!-i have used them for car stereo purposes in my european cars,had to repair a 6" woofer once the the voice coil wire was hexagon section aluminum.Some '90s volvos used dynaudio speakers,so i tried to buy some used ones on Ebay; apparently the volvo use was known to sound enthusiasts as these would always bid way up...I did manage to score a pair of 6"woofers at a pawn shop for a nice price-they were rebadged "alpine"-not sure when or for how long Alpine put their name on Dynaudio built speakers.
 
Yep B. Danielson!

You are correct. Dynaudio is Dynaco.
VW is using these speakers in the CC and the higher end Passats.
I have them in my 2015 Passat. The sounds is amazing.
Do you know if they are still making home audio speakers? I can't find anything out about that.

"PartsExpress had some Dynaudio woofers in their catalogs around~2000,but they were the very expensive top end versions in just a few sizes-including,IIRC,a very heavy cast frame11"dia.version

I am on Mad Men Season 5 from Blu-Ray. 

I was so delighted to see these Big Boy Dynaco Speakers in the Draper home!

Brent, this is too cool. Sharp eye sir! I think the set staff or dressers really try to be as authentically in the year/decade as possible. I was at Antiques & Beyond (large antique dealer showroom on Cheshire Bridge at Manchester) and they had a pair of these speakers. Pristine condition, they had a "sold" tag on them and from what I could tell they sold for 400.00 / pr. I wanted to open the front of the case but as like the pair above the grill is not easily removable. I have seen several high-end audio components at this dealer. One was a McIntosh amplifier that would still be very desirable and they had it priced out of my league.
 
Hi Michael

I think I know the sellers that had the goodies that you saw.  If it is the same person they get MOST of their stuff from Thrift Stores.  The other stuff is found at Estate Sales.  I see the guy everywhere.  I am sure he says that he sees me everywhere.  LOL!

A pair of Dynaco speakers this size was a good price at $400 as nice as you said the shape was in.  I would love to find a size this size...and of course pay only $20!  I had a friend years ago that had this size pair that his Dad gave him.  The sound was incredible. 

 
 
I keep watching for a decent set of Dynaco speakers on Criagslist but so far I haven't pulled the trigger on any. I suppose I might accept an old set of AR's also. Mostly looking for something from that period.

I own (or have owned, I sold the Mark VI amps) just about every Dynaco product made. Same applies to pre-Rockford Fosgate Hafler electronics. I have really enjoyed collecting, restoring and Resto-Modifying these old classics.

I tend to shy away from vintage speakers. Aging doesn't help these electro-mechanical devices, surrounds stiffen, radiator materials degrade and the crossover capacitors fail. Modern design technology, testing and manufacturing has improved speaker performance over earlier designs. Even if you could have a brand new vintage speaker its accuracy would pale compared to a modern high quality speaker today. It is of course true that high quality speakers are much harder to find now and you are likely to pay a mint for them though. Still we all likes what we likes for our own reasons and I can see merit in vintage speakers.

I do still search for a nice old pair of A-25's, one day I will score a pair. It will be neat to have a full system of an FM-3, a PAS, ST-70 and matching speakers for the nostalgia and agreeable distortions it will bring.
 
Hello Phil,

I think if you found a pair of any vintage speaker that was kept in a good surrounding area as far as humidity being controlled they would be just fine.  You can always tell speakers that were around too much humidity and such. 

Sounds like you have a nice collection!
