It depends on how many drivers were in the bass cabinet. They had a version with a single 15" and a version with 2 15" drivers. Then there were the horn varients. While they were essentially Altec 288B drivers...their Simplex numbers were LU-1104

Yep, they are the Simplexs with the 15 cell horns and two drivers. Used A4 to describe them figuring that most everybody would be more familiar.

The Fox in Detroit had their cinema speakers on a lift that rose from beneath the stage floor to expose the speakers and then lowered to make the stage floor level again. That was a lift like were used for organ consoles only much larger in scale.
That was "The Fox Movietone Lift" which was installed in the big Fox houses for use in the Fox theaters built in the silents period as sound shorts (like the Fox-owned Movietone process) were transitioning in. You'll find a Fox Movietone Lift in other Fox houses of the same period, like the Atlanta Fox. I can't remember if the NYC Roxy's stage construction was revised to include a Fox Movietone Lift when Fox bought into it during construction. Early RCA speakers in stage houses were often flown with the screen frame or "screen setting", & the Vitaphone HF horns rolled in behind the perf screen hanging from a track slightly lower than the top of the prosc. Modifications occurred during the transition to & optimization for sound pictures: one of the most obvious was that in the Fox houses, a 'pod' designed to integrate withe the theater's decoration containing the HF horns was added above the proscenium. Often they were hanging from cables, sometimes attached. The one at the Atlanta Fox was attached & so still there. These later-added pods were not used only in Fox houses.

Why do i get a feeling someone is thinking of flying a trio of them
Striking the screen speakers is a huge problem. A Fox Movietone Lift-like arrangement is the slickest solution, but trap space underneath the stage is just about as valuable as fly space. I'm thinking about a situation now & the best I've been able to come up with is putting casters on the bottom & back of the cabinets, then striking them by rolling them against the back wall & cranking up on a winch until they're out of the way - that will realistically be about the level of the fly gallery or about the height of the prosc. The wall at the back of the stage is probably the least critical space-area, but the speakers would need to be high enough not to interfere with backstage movement.

If you've got a crossover catwalk across the back of the stage at fly gallery level, you'd winch them to storage just below the catwalk. The problem is the stage radiators (please don't tell me they've mistakenly removed your stage radiators from the back wall, I don't want to go into how they work in the house HVAC arrangement again). Right now, the only solution presenting itself is 'tracks' of some kind of channel steel running just in front of the radiators, & neccessarily standing out from the back wall the width of the radiators. Castors on the back of the cabinets would theoretically run in the narrow tracks as the speakers were flown up the back wall. Or get all jammed up somewhere between stage level & fully out requiring some damn Spiderman act on a ladder to get them up & down.

The Simplex W cabinets? Blast from the past....
