Anyone have real world experience with this driver? Seems as though its the ferrite version of the N314T (same diaphragm)?
It looks like its only downfall is it falls off abruptly @ 13k…… could this be eq’d or would adding a (super) tweeter be necessary?

It's rated to 20 kHz, so historically one uses CD horn EQ* to flatten it to 'x' HF limit.
*RLC (aka frequency shaping) network or pot with HF bypass cap

Correct it's the electrical scheme of the pot Altec used. I said it didn't have one, the pioneers didn't need it, but we ideally need one to bypass the pot to keep the extreme highs from being shelved too.
So these psd3014-16 are on closeout special at the Eminence site on Reverb for $79.99 if anyone is interested…..I picked up a couple and some H14EA horns to try out (the unable to pass up a bargain disease!)
Theres hardly any information about them on the web?

What else do you need to know? I mean with a 411 Hz Fs/800 Hz power rating it's a 'brute force' PA horn driver just as advertised, so for HIFI/HT apps it can be used much lower and at typical fractional power will be very low distortion IF the horn is large enough.
Consider Altec/GPA's 802-8G 1" exit driver with a measured ~686 Hz Fs does just fine @ Altec's rated 500 Hz/2nd* on its 511 expo sectoral horn (~200 Hz eff. cutoff) and IME @ 800 Hz/2nd on a pure (conical/parabolic) DIY WG.
*a few disagree, but easily tweaked to 'taste' 😉

Got them today, didn’t realize how big/heavy they were (Even though it said it right there in the specs) good thing these H14EA horns are stout (1/4” thick cast aluminum) I’ll put them in the round tuit pile …….probably be a couple weeks before I can play with them. 😎
