Yeah, i know, senile old mans stupid attemts at beeing funny, not only joke thou, i often feel it seems Yove forgotten Your inheritance.

The classic american drive units from "the golden age?" 50´s to early70´s can´t be bettered or improved upon, maybe in a technical context, but not as reproducers of music.
They were also, to a large extent, handcrafted, manually assembled by people taking pride in doing a perfect job.
So going back is a good choise, my best time was a long time ago, wouldn´t mind going back (just for a short dash thou, dont think i´d survive one ordinary fridays activities from 1972).

Looking backward in anticipation of what You end up with.

Too often in our progression, we leave behind things should have held onto. I often wonder if we have forgotten more than we have learned....and I am a stupid young wakoo yank.

These all seem to fit the bill of the possiblity of good hifi SQ. Wife is not real keen on the Onken, says it looks short and fat. Women are funny about that sort of thing. What kind of enclosure are we looking at to get 40hz. I cant imagine needing more and I am not a bass junkie. Not saying I dont like it, but wouldn't trade speed and attack for sheer Lf extension. All the above drivers are similar, with exception of TD showing much lower Vas. It does have extremely loe Le, which should be nice for HF extension.
TD15m
AE Speakers --- Superb Quality, Unforgettable Performance, Definitely.

What kind of box size can I expect fomr above drivers for 40hZ -3dB ?

Do you still say 515, giving up low end for better mid?
Or build mid-bass horns.

I can, the 2235 was JBL's 'answer' to all the tube era combo horn cab drivers that couldn’t handle the then new SS amp’s high power/hard clipping, ergo had a high enough Vas, low enough Fs, Qts to get good acoustic efficiency all the way down, so has GW posted any measured specs, plots yet?

If the ‘2236’ is a good choice, my only concern would be long term ability to be repaired in case of an ‘event’.

There’s also TAD, Beyma, Radian among others that make ~directly competing models. After all, plagiarism is the sincerest form of flattery [road to profit].

Hmm, I started this the other day, but see you’ve bought some ‘flavor’ of 416, but would still choose the 515-8G if for no other reason than its Fs is close to ideal for the app’s desired BW, though for sure, I’m heavily biased towards the 515 series whenever it meets the needs of the app.

BTW, in a typical HIFI/HT app with a ~40 Hz-up tuning, the 515 doesn’t give up any noticeable LF output compared to the 416 due to both typically needing to blend to the room’s gain curve, so any LF advantage the 416 might have is otherwise unusable plus the 515 has a higher efficiency as well as a much greater HF BW [the originals anyway], though historically not marketed as such, so the ‘no-brainer’ choice for me if the more exotic offerings are beyond budget.

Which 416 BTW? Original or re-cone? If the latter, then specs tend to be a crapshoot WRT OEM specs even from GPA, so will need to be measured before considering and designs.

I havent actually gotten the 416's yet. I am watching a pair of 416_A's without the cover. Shhhh. Reason I was hesitant on the 515 depends largely on its cost and the fact that I cant seem to find any use except for a A7 type box. I can hear the wife laughing now. I come from geetar family, so I have a bit of an affinity for Alnico magnets. The 515's are $1000. Just cant do that considering all that is left to be bought.

Yeah, all things considered, buying new from GPA is probably the best deal overall. You for sure wouldn't get either of my pair of Bs for a grand.

There is a good possibilty that i will end up with a pair, bur the 416 is a step in. Big Cal has suggested that the 421 is his favorite Altec for mids. This a very inexpensive entry pount as well. I think that they can be reconed as a 416, but cant quite get my head around the change.

It was marketed for horns, so A7, A4, etc., but works fine in a vented alignment also. This ~8.94 ft^3 net MLTL based on the 40” internal height of the 2226 sim doesn’t look too shabby to me once the room’s gain is added and unless driven with a high output impedance or at high average power, I doubt you can hear a difference between AlNiCo and ceramic:
