Gonna need a 30A circuit for that beast, or 220-240VAC @15A:

Progress! :)

"Get ready, collectors" :rotfl:

I'm old. Presentation blew chunks as far as I'm concerned.
FWIW, 24:50 gets you to the "Luxury" element.
Won't get that time back.

D220Ti test condition? on a 45º exponential horn, on-axis (HL14-25 plastic trumpet).

Unless that is your application, that test is useless without interpretation.
Look at the spec pdf (available...

Selenium D220Ti is a $50 driver from Brazil and is a screw on driver.
JBL D2415K is being sold new for over $300 (even used on eBay), is .8" exit, and bolt-on (would require an odd adapter and could...

511 horn maybe? 802d being just the compression driver. Fun/efficient setup for a lowish-powered tube amp.

Just noticed there's a slimmed down version in the works (sans balanced i/o) for a bit less:

Interesting (thanks for posting the link), but also uninterested.
Kind of sad looking vs nostalgic, and I’m not in the licensed-tech powered-streamer demo
It will probably sell.

A four-way system would be my initial/personal suggestion then, perhaps a more modern iteration of the formula.

Having a mid-bass driver makes a difference. There are multiple build examples with...

Looks nice and very clean!

For your next project, is this anticipated as a 'period' setup and a stock driver JBL system complement?
Is biamplification an option? (e.g., Tubes on top)

Well, congrats and condolences. An unfortunate start for a fairly reasonable sounding system.

Can you define 'flat' a bit more? e.g., no bass or no highs?
Just one speaker or both?
Can you put...

Haha, from like 50+ feet away (please).

2360 w/ appropriate horn contour/EQ. Sounded awesome. EQ’d low end (a bit... I’m not a basshead or subs would have been necessary). Had 2226 w/spacers in the 4560s. I believe I had SL dias in 2446...

Main thing is that the schematic shows electrical connections -only-, not physical or location/placement.
Also it gives no clue to keep track of which end of a component is which (unless, like an...

1) Happy New Year

not mine 😅

No expert here, just what I’ve picked up along the way :)
(and a 416b/511b set waiting for action).

IIRC, folks have flipped that cab, which gets the mid/woof up higher, and blocked off the horn...

A5 - 515 variants
A7 - 416 variants

The horn and driver were also varied over time and options. Looks like A5 usually had a large format compression driver (288) and bigger horn.

Expecting...

As a minor addition to the good advice already provided, the screen in the dustcap can come partially loose, and IIRC, there's a metal disc glued to the center of the magnet on at least some 416...

One could... 2425HS or 2426 w/o the spin-on flange, but this sounds like a dead end now.

roughly similar, but no (from what I can see).

Seriously. Anything else is last-resort kind of stuff for a factory system.
Hope there is some success with the dealer, etc... that would be fantastic.

Off topic:
I need to get back into a mode...

Thinking outside the box a bit... TruExtent Be diaphragms might at least get you a matching pair... probably less than 1/2 your new driver quote.
Would take some serious homework to make sure they'd...

Haha... glad to be useful.

Sooo... not touching that poll with a ten foot ... oh, never mind.

Might want to give this a look for fun:
