    "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.

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

    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.

    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?

    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...
