Are they firecrackers on the bottom of the cab?
I surely have seen 804's/806's in the Frazier blue with Frazier decals.
I don't recall ever seeing an Altec cone driver of the same convention.
Without being disrespectful, i would opine that Jack Frazier subscribed somewhat to the PWK school of economics where the sourcing of drivers was concerned, and then tried to make the most out of them via cabinet and horn engineering.
They certainly used EV drivers in the later and larger Fraziers like Texans. The Frazier F-1277 woofer is a perhaps modified, perhaps not, EVM-12L.
This is a Frazier X-15 with an Altec compression driver and CTS or Jensen woofer:

Wow I just noticed all those caps. I count 16 caps and a single coil between them. I am guessing they used a bunch of smaller caps to equal a larger value?
There's a second coil hiding off to the left side, it's axis oriented 90 degrees to the other coil. Bundling them in masking tape is a practice that carried on into Fraziers made in the 90's.

Gotcha I see the second coil now. Looks like a simple second order xover then
Correctomundo and at the values that most Altec, horn speakers require should be done with caps and resistors IME, but gave up 'beating this drum' long ago as a lost cause.Originally Posted by Elitopus1
Maybe by now there's some good info on the subject for any interested even if it's just for power factor correction capacitor banks and [now obsolete] industrial primary resistor motor controllers.

No doubt, the pioneers figured out early on [1936?] that a 2nd order XO wired inverted offset a horn's driver back in time to align 'close enough' [<1/4 WL] to the woofer and if the woofer was physically aligned with the horn, then it could be wired in phase and time aligned.
Fast forward to the '80s? and all of a sudden someone [guessing another now prominent horn manufacturer and/or one marketing cone dome 'monkey coffins'] 'invents' this very mature knowledge, making Altec in particular look like a dunce, which in retrospect they were for not making a 'big deal' of it way back when beyond the 'A' series horn intro; or W.E. for that matter, 'grandfathering in' Altec Lansing.
Nowadays, time/phase alignment is mandatory to the point of passe' in prosound and pretty much all decent consumer, DIY to boot with the advent of cheap/free computer measurement software, relatively cheap calibrated mics.

Its a good thread when we go from talking about Altec duplex, to Frazier, and end up with a Rush song. Thats how they all should end!
Weird, I was thinking similar as I read this while listening to Guns n' Rose's 'Paradise City' on the only 'classic' music radio station left in Hotlanta. Now if it only went back far enough for me............ Oh well, got gifted several of those PBS 'best of' sets some years ago, plus there's the on-line jukebox's, so got it covered from 1920, my parent's time.
