My Frankenspeaker: with 1957 Altec 803A & 802D, crossing over around 1200hz.
Jensen Triplex cabinet. Love the 803A but my being petering out to soon. Will try the 414A.

Cool setup!
Seems to me that the 803A might squeak up to 1200hz but I'm wondering if that little horn can play comfortably down that low. I haven't tried it yet myself.
Altec LF specs on some horns are a bit ambitious, or perhaps tuned for presumed lo-fi applications. I have scavenged 32b horns with cheap 720 PA drivers attached as used for full-range paging/announcement service.
The 414A/Z can play full range without sounding scratchy and garbled, so you can get the crossover out of the vocal range and to a point where the horn is cruising easy.
As reported above, I was digging the sound with 414A full range and the 32B horn floating in at 6k or so, first order, but the setup could easily handle a 3k xover and all of the drivers would be happy. The 414 and the 32/802 were extremely well matched in "flavor" and a natural pair.

Thanks Joe. The horn will eventually end up in the cabinet with the driver facing up. My set-up sounds much better in the 828 horn cabinet, blends nicely. I've gone mono for a few years now, really don't miss the stereo effect and much easier to integrate into my home.
