One thing I am looking for is any information on the IPC, Simplex XL, Simplex W, etc.

I'm hoping to keep the whole set together for posterity's sake as a piece of living sonic history.

In the mean time I'm searching for more info....

Not sure what you're looking for, but Steve and I had this brief conversation WRT Simplex awhile back:

Originally posted by Steve Schell:
[QB]I found a photocopy of a 1940s Jensen catalog. They picture a W bin, described as type "WK", that looks a lot like the auction bin with tapered sides and sharp front peak but is a larger full size bin. Two models are described, one for two 15" drivers and one for two 18" drivers. Stephens and Electro Voice (among others) made large theatre W bins which are shown in their catalogs. These were made well into the 1950s, long after Altec's introduction of the VOTT.

One funny story- a retired RCA engineer told me that a persistent rumor at the company was that RCA had contracted with a casket manufacturer in the 1930s to construct W bins for them during their slow times. Some of those old RCA bins do have rounded features that suggest that this might have been true.

I have never quite understood the relationship of International Projector Corporation and Simplex. I.P.C. installed complete theatre systems, which usually included audio gear made by Lansing, Altec Lansing, Jensen or others. The projectors were the Simplex brand. Sometimes the Simplex name appears on the audio gear such as the speaker bins. Does anyone know whether I.P.C. and Simplex were separate companies or just two brand identities of the same company?[/QB]

Greets!

It's my understanding that an ex-Edison employee bought a machining/manufacturing plant to build what became known as Simplex projectors, which later became known as IPC as they expanded, with Simplex as a brand name. I know Altec made Simplex branded theater systems and while the components were stock Altec, the cabs I saw were somewhat different in design. Frankly, they performed better IMO, but they were smaller, so required more bins for a given theater size.

So much for my limited knowledge! You got me curious, so did a bit of Googling and found this, which 'fleshes' out my bone thin synopsis: http://www.film-tech.com/warehouse/m...IMPLEXHIST.pdf

Those are some nice looking bins, AA. They look like a mini-211, in a trapezoid box. Can you measure the mouths to give us an idea of their size??

The 210/211 has a mouth of 34" x 60", and a flare depth of 29".
The 815 has a mouth of 34" x 42", and a flare depth of 24".

Thanks.
