I just bought a couple of these. The spec says that the top plate
where the horn is bolted to can be removed so that a 1 3/8 18 TPI
type horn lens can be thread onto the 2426. Does anyone know how
to remove the top plate? Do I just turn it counter clockwise real
hard till it moves or do I need to unscrew 3 screws that are located
on the bottom of the driver, where the binding post are located.
Thanks

By topplate I presume you mean the snout on the driver that the horn bolts to. You simply unscrew the snout. Might be harder than it seems, it can take ALOT of pussy to remove the snout. I bought a pair of 2427s, same driver but with a different snout, goes out to a 2" opening. Had to put the snout end of the driver in a large vice and remove the driver from it with a 36" pipe wrench and I needed the 36. And I'd already spritzed the thing with Kro-oil. No kidding. The stainless threads of the driver gall the aluminum threads of the snout. The indentations on the driver cover were perfect for the wrench to bite on, did the job without a scratch.

Kroil! I had a gallon of that stuff that I bought around 1983. I gave the remainder to a buddies dad around 1985. He passed away a few years ago; we were out cleaning out his workshop/shed and I found the can about 1/3 full still. Multi-purpose. Actually some good stuff, eh?
