Thanks for the link GM
I apparently have a lot to learn about horns.

The 32 is a curiosity as I have read somewhere that is sounds more natural than the 811B. All subjective I think. You would need to do a serious experiment with optimized crossovers and drivers and matching woofer systems to really determine any differences.

Yep, too bad I don't have any test equipment, am tone deaf, and just plain deaf.

753C definitely uses a 15" Jensen. Cone is softer than the bakelitized paper PM15 and such we know....and sounds better than my accumulated Jensen experience would lead me to expect.

The best sounding 753 version is the A which uses the 752 PM horn tweeter and 722A driver. Pretty rare though. I closely compared the "A" and "C" a few months ago. I formerly thought the 722A was a PA driver based on looks but it plays really great midrange. Live and learn.

I think the 757A is a big step up from the 753 series though.

There is more going on with this 753 speaker than meets the eye. According to on old RCA engineer I talked to, this speaker was carefully dialed in for phase delay, a concern of WE engineers since the 30s (594A driver). I'm intrigued by the very high DCR of the inductors. I forget the figure but over 1000 ohms, I think. So much for damping factor, which is probably precisely the point.

Over the past year, I have been messing with 32B/C horns and 414s. I ran the 414A full range in a small Onken and cut in the 802g/32 very high first order, like 8k. Then I switched to 728Bs in 3 cu ft sealed cabs and did the same thing. Both experiments sounded pretty dang good...to the point where my further crossover experiments sorta never happened.

I'll get to it, maybe...

To my ear, a metal or plastic 32 horn smokes the 511B in overall musicality and listenability, but I am a known staunch and highly vociferous 511B and 811B hater. Gave the 811B another shot, for the 10th time, vs the 32s then gave them away to the guy who bought my Onken cabs.
