    After reading about the dispersion characteristics of 4x10s and vertical 2x10s, I’m looking at my 4x10 and thinking of adding a switch to go between the two configurations. Has anyone done such a thing? If so, how did it change your sound?

    You may be better off wiring it so you can remove the high frequencies from the left (or right) two drivers. I have no idea what cutoff frequencies or how to do it. However, Barefaced does this with their 4x10, 6x10, and 8x10 cabinets.
    It allows one side only to produce the higher frequencies, allowing for better dispersion.
    I'm sure a search on TB will have better information on this type of modification

    Yes by switching off one of the vertical pairs

    The big question is whether the cabinet is divided internally. Its for certain you don't want two speakers active and two being pushed about by the pressure changes in the cabinet.
    If the cabinet is suitably divided you next have to figure out the wiring to get a suitable impedance. Then connectors. If you use jack sockets it would be possible to do something clever involving switched sockets, but generally Speakons are not switched (there is an exception according to the Neutrik web site, but its a PCB mounting type).

    Convert 4x10 to 2x10:

    Sell 4x10, then purchase 2x10. :D

    u already have two vertical 2/10's, they are next to each other

    2xSVT210av = A great sounding, more convenient 4x10.

    The thing about that dispersion talk is about using 2, 2x10 stacked vertically one on top of the other. By turning off two of the tens, you still have the cabinet, on the floor. You've solved nothing I'm afraid.

    With a normal bass and a good player.

    all the mystical magical dispersion is meaningless
    4x10 works fine.

    but if you wanna go vertical
    which yes in true science helps mystical magical dispersion.

    instead of a 4x10 which became a standard for bass more towards the late 70s and went full on in the 80s

    the other standard which achieves pretty much the same max SPL
    is the other standard for bass way way way before the 4x10

    The 2x15
    totally amazing concept
    and yes a 2x15 is already vertical
    and it handles way way way more power than a 2x10

    otherwise you use a crossfire or splayed 4x10
    which gets superior dispersion
    Sunn made them a zillion years ago.
    but they " look funny"
    so people dont think they work or sound right.
    in reality dispersion is superior
    but nobody will ever buy them lol

    so you just go back to the good old 2x15

    or yes you can use the stupid waste of driver .5 alignment
    or you just use a 4x10 or a 8x10
    run your signal to the main with the amp or DI like the rest of the planet
    and completely ignore most the dispersion magic
    and just use a freaking 4x10 or a 2x15

    You can lo-pass the left side drivers so they only provide content 500Hz and below. The right side stays full range. That will solve the weird dispersion/interference you get from side x side drivers as it typically affects frequencies above 500 Hz. You’ll need a big inductor. I did that to a 410 I used to own.

    AKA .5 alignment.

    That’s what Barefaced does.

    Do those crossfire cabs actually have useful properties, or were they just one of those things that seemed like a good idea until real science was applied?

    Well how many do you see in use today?
    Exactly! :)

    I do not understand why you wouldn’t just sell what you have to get what you want. Unless what you are asking for is a half-functional cab that weighs more than it needs to?
