To be specific the early Iconic cabinets where the top, bottom and side
plywood edges are visible on the front
Needing the measurements of the Front Baffle cutout
for the Rear mounted Speaker.
The width of the side of the frame like appearance it forms
also possibly radius of the curved corners
Viewing the 1943 catalog The outer dimensions are easy to find.
39.5" High
25.5" Wide
17.75" Deep
Need the front frame measurements
I am basically using the model numbers from the 1943 catalog
Page 2 , Figure 1 and Page 3
Specified as Model 812, 812-PM, 814, 814-S
all basically using the same bass cabinet
with different options for field coil or
permanent magnet and higher gain amplifier
for phono/microphone
Which is why I titled the thread as So.
But if anybody has other useful Numbers, Model
Numbers or Search terms related to the Iconic
please suggest or provide links.
Only interested in this cabinet/baffle style
The General Purpose Model
Early Cabinets where bottom/sides
plywood edge is visible on the front.
Links, Discussion, Owners, useful search terms,
and Plans
Incredible welcome.
Far as Snobs and Negative Technical
Jibber, about why its old and no good.
I DO NOT CARE ! DO NOT POST
Positive discussion, fans and plans

You know the overall width and height. Print out a picture and measure with a compass and you will be pretty close. They probably used 3/4" plywood so thats another point to work from. When printed if the width is 5" then 5/25.5 Is your ratio. Multiply any compass measurement by 25.5/5 to get what you need.
Good point and might come to that.
I was thinking a overlay in SketchUp
Was just hoping a owner or actual Lansing plans
might pop up.
Even possible builders of replicas
Its hard to title a thread
there is plenty of detailed plans for
many " Iconic Cabs"
These early cabinet plans just dont show
With extensive searches and terms.
Which is strange since there seems to
be a lot or good amount of replicas
out there
Hi WhiteDragon,
I think that a friend may still have a pair. How much in a rush are you?

1943 catalog calls it 812 ,814
must be the total system name.
Finding better results since the cabinet has
been identified as a 612
Just numbers I'm finding in searches
As mentioned in OP was hoping
others might have more specific info.
Or search terms

That would be great.
Either way more info may pop up in the meantime.
But actual real owners are Golden
since they could confirm actual measurements.
Measurements for the sake of my project.
Likewise any info / archive that may be valuable
to other people
The overall look for some reason is captivating.
And the historical part of it is amazing as well.
From the overall dimensions, this cabinet
seems very well suited for many Live sound 15"
drivers for a alignment needing med/large
volume.
Guess they got it right from the start.
T/S parameters / Reflex
are associated usually with 1970's
from the Lansing Story seems
it dates back further to late 30's
Referred to as " Resonate Baffle"
Hi WhiteDragon,
since the potential owner lives under the Internet rock, I have just sent an e-mail with your picture to a mutual friend, who visits form time-to-time. So we'll have to wait.

Bingo !!!
Be great to confirm this since the 1943 catalog might be stating 39.5"
Tall , including the Multicell Horn.
Actual Cabinet Height 29" ??

This is the drawing I remember, though otherwise all the ones I've seen listed/dims are 29.5"w/flush seams such as in Altec's 1945 catalog through at least the '70s:
Well, it was the original thanks to Les Paul.
Yes, the more I studied the pioneer's work the more it became obvious that they had it figured out to the limits of the available technology for the various intended apps of the times.
Yeah, 1936 is the earliest I know of. Here's a barely readable description once blown up of the 812 you want that appears to be 29.5" also.
Yes interesting.
Might have found a interesting fact.
It does seem in 1945 is where the " Utility Cabinet"
Name was used.
Most the photos I see is the silver painted versions.
And it is when the plywood edges are not visible on the front.
So the 70's plans and the 1945 catalog
both show 29.5" height
Beginning to think the early 1936/37 to 1944?
where the plywood edges are visible
" General Purpose Models "
Might have been a 1/2" shorter at 29"
I got the plans posted from this thread
Altec 612
Made by a owner
Be interesting to know? or so it seems...
very early cabs are 1/2" shorter, with
visible plywood edges on the front.
I dont why but the whole visible edges
thing, really looks cool to me.
Such a statement in simplicity
I'm just happy to have dimensions
and laid out in sketchUp.
Everything seems to line up, and is
symmetrical according to what was posted on
the Lansing Heritage post.
If I was rounding the edges and painting it silver.
I would definitely use the 29.5" height.
Guess I'm just curious if factory cabs
had that much variation.
Or if the early cabs were shorter.
Either way, still happy and can work
out additional braces.
And looks like 3x 3" round ports
will fit on the inner baffle.
I will be able to tune to whatever
driver I end up using.
Glad the 25.5" width stayed consistent.
Since Im working on a 24" Exponential
Horn for a Mid

Hi WhiteDragon,
I am glad that you found the dimensions because my friend just e-mailed me that our mutual friend sold the Iconic a few years back. However, the drawing in post #13 is the measurement that my above-mentioned friend (Steve Schell) took, so you can be confident that it is correct.
Just in case you still have some doubt, there are few posts regarding Iconic in the following links, so perhaps the people already have plans?
