re-read please and put it back;
it isn't related to preceding tomtt's post in any way,especially because is posted before his last editing.
I demand explanation what is the reason.

I love Altec too, over the past 15 years I have found myself restoring quite a few A4s and A7s in cinemas around sydney. My favorite find was a former CINERAMA modified multicell horn, lead lined and sand filled, It sounded amazing, if you have a standard one I do suggest you modify yours, you would never regret it!!!

Personally I would be carefull of running Altecs to loud as apparently a few theatres burnt down in america when the original valve amps were replaced with hi power IC ones . They are plenty loud enough at 60 w

Other thing worth trying

open cell foam inside the box instead of fiberglass, pointy style (matress underlay) placed directly behind the woofers helps break up the standing waves that reflect back through the cone.

anyway enjoy



anyone know how much a couple of original A4 crossovers are worth, I have some altec horns and compression drivers lying around ect

I don't have any Altec speakers per se, but I used to use a 511 on top of a JBL 15 for my bass guitar rehearsal rig.
Now it's just stting unused in storage until someone buys it.

Hi Mr M,

I was hoping we might see you here. I agree with your thoughts but...

This is really just something to scratch an itch or repair a wound, I'm not sure. I haven't built anything to speak of recently and have the 811's sitting on the shelf gathering dust. The darn 825 cabinets are in the garage with me while I work so I keep looking at them. Again and again I stare at them. And then it hits me, the horn that is, it falls off the shelf right onto my head.

I had a vision. I knew what I had to do.

One thing led to another and the mids were on their way. What can I say? I don't try and suppress the signs, I simply go with them.

I have lined up the flanges on a double slotted board with about 1/2" between them and supported the backs. Looks pretty good.



My name is Cal and I'm a speakerholic.

Yes, to my surprise, the WAF is way above average. That's the first speaker I have that gets wows from the female visitors.

The version with 902 and tractrix horn wasn't accepted so well

"Had to sell 'em to moved to Oz??? Why? They have more room than they know what to do with down there."

I have 95 acres out the back door. And no big Altecs running at the moment. I wonder if I could borrow Cals on New Years Eve.

I mentioned Model Nineteens some time earlier today, when I should have said model 9's. The 19s weren't here then.

You big horn guys have frightened the home models, so I'll break the ice with these Atlantics. I haven't much info on them. They are similar to the Model 1s. These were made April 81. The bass driver is similar to the 755. The magnet is smaller, and the cone slightly different.

I have been looking for the original data sheet, without joy. I got these for nothing, with a NAD Model 120 Tuner amp thrown in. That's good value.
