Pictures of the original Speakerlab SUPER 7
« on: 30 Sep 2012, 11:08 pm »
Here's some pictures of the speaker that Danny's SUPER 7 speakers are named after. If you had a pair  of these in the late 1970's, you ruled the world. I got these from a guy on craigslist about 10 years ago. I thought he was going to cry when I wheeled them out the door. This guy had built double thick cabinets that were an inch and a half thick in back and I think an inch and 3/4 on the sides. These are Heavy with big magnets and overbuilt cabinets. Speakerlab at the time recommended sealing all the drivers in with silicone, and you can see that in the pictures. Also, there are volume controls on the back for the mid and high frequency horns.






















I"m sure these speakers have seen some loud parties. If they could talk, they would have to be in the witness protection program. I think the woofers were configured in a "Nestorovic" alignment in which the 10" woofer decreases output as frequency decreases, while the 12" woofer increases output as frequency decreases, and they both cover the same frequency range. I might be wrong about that. Maybe somebody else knows what I'm talking about?
Btw, I'm looking to sell this pair for $100, and I can bring them to RMAF, but No shipping. I'm in Denver.
These speakers are "white dog approved" and digital ready!

Those  are Samoyed Dogs. Also known as Sammys. The top picture is Ruby, who is 3 years old, and the bottom 2 pictures are Ruby's mother Maggie, who is 8 years old. Samoyeds are used by indigenous tribes (also named Samoyeds) of northern Russia, and were used in the arctic expeditions. Very smart and people oriented dogs.

There were a number of "revisions" to the 7 model.  It's difficult to tell if those are earlier (original) 7's or a slightly later version they called the Super-7's.  (There were even later versions of the Super-7's with a different driver compliment.)
You'd need to look inside at the midrange compression driver to tell for sure their vintage.

Anyways,  I purchased the very first pair of Speakerlab 7 kits from their store on 45th and Roosevelt in Seattle a loooooong time ago.  :)  I had them for years.

You could buy the kit with an already cut front baffle and then you supplied all the other particle board to build the rest of the box.  The cutout for the Electro-Voice tweeter was rectangular, but on the sides there were a couple of half-moons required to fit the round portion of the compression driver through.  This left a couple of "vents" that had to plugged.  The Speakerlab guys recommended tongue-depressors for this job.  :)  The fella that built your speakers has done something similiar with the small strips above and below the tweeter.
The woofers were CTS models that had decent performance and the tweeter was the classic Electro-Voice T35.  I can't remember the model number of the mid driver.  It was the weakest link in the design.....IMHO.

They used to have speaker building gtg's on Saturdays that were a lot of fun.  Good times.

Cheers,

Dave.

Wow, I think those are some really early versions. I remember a very different looking model.

Thanks for the info, Davey. I never noticed the strips on the top and bottom of the tweeter. Also, it's cool to have the first example of such an important speaker. Did I mention that I have the first pair of LS-9's ever made? :thumb:
Danny, you said the 7's that you saw looked a lot different. Were they taller, and did they have a 6" midrange on top, a 1" tweeter below that, a 10" woofer below that, and a 12" woofer in the rear? If so, those were the DAS-7's. They came after the super 7's. I loved those speakers, and still have a pair my brother-in-law helped me make in the early 80's. I rocked on with those for over 10 years .

The pair that sticks out to me was a four driver design. I want to say it had a dome tweeter, a large dome mid, and two woofers. There was an ad for it that pictured a body builder from the back side holding one of these big speakers up over his head. And the header said Super-7.

Hmmm... That design doesn't ring any bells with me. Sounds a little like the ADS speakers that were popular in the 70's and 80's though.

Yeah, the later versions had a symmetrical layout with a couple of different driver compliments.  Unfortunately, if you Google or Bing images of these speakers many of the photos/captions are incorrect.  :)

I wouldn't call the original midrange/tweeter drivers unorthodox.  At the time, those drivers were used in a wide variety of speakers, both in the professional world and for many domestic designs.  I think a person might be surprised how many of the T35 tweeters are still in everyday use.  :)

We were still (essentially) in the low-powered amplifier era, and high-efficiency designs were commonplace.  The Speakerlab K-horn was a kit version of the famous Klipschorn, and the fellas at Speakerlab produced many of those kits.  Imagine a speaker that could play at very decent SPL levels with what we would call a headphone amplifier nowadays.  :)

Everything turned upside in the decade after that.  Amplifiers became much more powerful and speakers became much smaller.  It was the downfall of the speaker design industry.....some would say.  :)

Cheers,

Dave.

Yep, I think that was the one that the body builder was holding over his head.

So, doing some more research, there were 2 generations (at least) of the super 7's. The ones Danny saw were the later versions. The ones I have are the earlier ones. The other model that jparkhur found with the 5 drivers is called the "Delta I type 5". Speakerlab made a lot more drivers and speakers than I was aware of. They made their own woofers and some mids and tweeters as well.
The later versions must have been pretty heavy judging by how tired the weightlifter looks.

I live in Seattle and was a frequent customer and lurker at the speakerlab store, from the very first days in the early 70s. In those days I owned models .1, 1, 2, 3, 6, super duper7, and 30.
The super 7s in the top pics were the original versions, with the wooden slats to cover the round holes where the magnet slipped in, and walnut veneer cabs. They did not have a Nestorovic alignment, which came years later.
There was another top line version for awhile, the "Super-duper 7", that used the 350 cycle midrange horn from the K-horn, mounted on top of the woofer box, with the big EV horn tweeter. I owned a pair of those. Can you say "Rock and Roll"?
Later the walnut veneer was replaced by vinyl. Still later they used "wave aperture" horns for mids and tweeters, similar to the Klipsch tractrix geometry, vertically stacked with the 12 and 10, in a larger box. Still later they went with polypro midranges and woofers, leaf tweeters, etc., which really weren't the same speaker at all. The drivers were far cheaper than the EV and Atlas horn drivers they had been using in the classic 7 models.
They got connected with  Nestorovic for  the woofer section of the model 30, which was pretty good but used cheap mids and tweeters, and for the 50, which was the best speaker they ever made, and a truly great speaker, similar to the delta shown above (with glass tops, a la JBL).

The speakers you own are very cool, and a giveaway for $100. If I was local I'd be at you door, for sure.

It looks like you are going to have to go back to the drawing board to redesign your new ones.   :duh:

Hey Jonbe, thanks for all the info. I didn't know the history of Speakerlab was so complex. The superduper 7's sound awesome. Are you sure you can't make it to RMAF? I'd be glad to bring them there. I'm selling them cheap because I got them cheap and I want someone to have some cool retro mancave speakers or garage speakers. Or they could go in a museum. Other than my museum that is. Really, someone should open up an audio museum, and maybe build it next door to the rock and roll hall of fame.
Hmmm.. if you hung out at Speakerlab, and Davey hung out at Speakerlab, what're the odds that you  guys know each other?
Sounds like it was almost as much a social club as a speaker company.
Here's a posting about the model 50's I found
