I need info on Atlantis speakers!
- Thread starter sloppy
- Start date
Those numbers should normally help, but I'm not finding any manufacturers for codes 905, 122 or 247. Usually the manuf. code is the first 3 digits, but I'm not finding anything for 905 or 247.
The last 3 digits are the date code, so it was produced either the 22d wk of 1971 (122) or the 40th wk of 1977 (740).
I've been told (you might check the other Atlantic/Atlantis threads) that the drivers on these were Peerless. The only Peerless code I find is "Altec-Lansing - Peerless" which is 391. I don't know the history of Peerless or whether it was always part of Altec or once had its own code.
mtlm: Looks like you have a different animal entirely. If that speaker was made by the same co. they must have had a Three that was distinct from the Oracle 3.
Is the tube open at the other end so you can see inside? I assume so if you could get the numbers.

If you ever hope to find a matching original it will help to have a pic of the rear of the driver.
Not to insult your intelligence, but have you confirmed the driver voice coil is open? It's not a bad cap or resistor in the crossover, bad solder joint, broken wire, etc.?

No, the midrange works, the pair of speakers only came with the one midrange.
The speakers were given to me in very bad shape. Was not sure they would be worth saving.
I have another question while I'm at it. One of the woofers had/has some major damage. Wondering what will happen when I use it.
Looks like the woofer was used after the surround gave out. The spider disconnected from the cone, and because it sat for what I'm assuming some time the spider has deformed. I was able to glue the spider back onto the cone in its proper place.
Would/could it help to reshape the spider to its original form if I rotate the woofer in the cab, or would it be a waste of time?
(The first two pictures are the mid range and the last three are the woofer.)

Spiders are flexible -- that's their purpose -- so they can return to their original shape and position. Assuming that you have attached the spider to the voice coil pretty exactly, it ought to be okay as long as you get the surround located correctly. If you haven't already refoamed, I would suggest using balls of tissue to gently force the cone in the opposite direction of the original sag, and give it some time -- a week or two, maybe more -- to readjust. A little moisture might help, too. Breathing heavily on it (which comes naturally to audiophiles) might be good, or maybe a little mist or damp cloth, but stay away from the cone, and don't overdo it.
It will be a lot easier to refoam after than before.
I bought a pair of TruSonic 15 inch woofers that had sagged as far as they could over several decades face up, and over several months this method returned them to perfectly normal position. Boring, but effective.

I assume you are pushing down the high spots on the spider. That is probably a good idea, but not if the end result is pushing down the whole spider. I would guess it would be good while you have the VC shimmed, to make sure that the cone position is high enough that there is a little tension on the spider in order to bring the low parts up.

What you have described is what I have done. All is set to even out the spider and not put stress on the spider over-all. Now If I can find a midrange I'll be set.
I'm also looking for surrounds, I used to go thru John McPeak. But it seems his email address is no more, at this point I have no way of contacting him, any suggestions on surround replacements?

Hmm, this is easier said than done. Impedance and sensitivity are the big things to match. Impedance is probably the same as the overall speaker (8 ohms). Sensitivity is harder to determine. If you can ID the driver and find a spec sheet for it somewhere, that's the best. It's possible to measure it with fairly basic test equipment.

I found a pair of Atlantis 3 speakers at the thrift store today, but passed on them at my wife's pleading. I'd never heard of the Atlantis brand, but they looked to be 60s-70s vintage and incredibly well-built. Seriously, things were like tanks. The woofers were in great condition, and they had a weird inverted surround. Google isn't helping me, and Google images for "atlantis speakers -outdoor" yields one old ebay result with a thumbnail pic that is what I saw, but the auction/link is dead. Does anyone have any information or links? I really wanted to give them a listen
Wish I had see this site years ago, I've always wondered about these speakers. I own 2 of these speakers, they weigh about 50 lbs each. The wife wanted me to throw them away but I have them stored in my shed covered up. I can take more pics later.

Oh yes, definitely worth keeping. Do yours look like the III's elsewhere in this thread? Please post more pics. And the label on that beast looks like it says 63.5 lb. Use proper lifting technique. 
That's a very generous offer. You might want to place an ad in the AK Classifieds forum for more exposure. Likely someone here from your area would take them off your hands with no shipping.

Thanks but I've decided to just donate them.

Have a set for sale! Go see!

Hi. I have just picked a set of Atlantis 3-A speakers up at an estate sale and have been trying to find some information on them. After searching every way I can think to search them it looks like the info you have posted is the only information available on them. I was wondering if you might have any additional information or know where I could potentially find some? Love the covers for these speakers, very different black foam covers with stand up 3D 1.5" circles covering them...very cool look. Not so impressed with the looks of the speakers, though the inverted surround on the 8" Subwoofer makes it a little more unique, but is ruined by the large chrome center cap. Anyway any information is appreciated Thanks in advance
