    Weird question, and I think I already know the answer. But anyway...
    I have a chance to get a SuperChampX2 head for a reasonable price. Rather than get a cabinet for it, is it reasonably possible to use a PA monitor? The SCx2 is already performing some amp modeling, so I'm thinking for that kind of head I might be able to get away with a PA speaker. I guess I would need to check the impedence is a match. And I'm not sure about the horn, how that comes into play. If this idea just more trouble than it's worth? I would only consider doing it if it saves me cost and effort, not adds more. Thanks,

    As long as ohm are good, anything goes(see below Cipollina rig), however,
    that said, a angular cab, with a 15 hi fi monitor might
    not sound good on certain tunes you play. The
    directional type cabs are that way for a reason.

    Try it. You may want to unplug the tweeter or horn. Or not.

    P.A stuff tends towards full range and a guitar amp straight into it may set your teeth on edge. A P.A -usually- amplifies a mic'd or compensated D.I amp rather than the full amp. You'd be surprised how shrill a guitar can sound.

    Disconnect the horn. Horns sound great when used for F.O.H, ie, P.A duties, but for guitar?, that's a solid nope.

    Try it. As long as the impedance matches, you may like it.

    Note :- If you have a Joyo American Sound or similar, it applies some frequency compensation to reduce the honking glare from P.A.

    It will be very hi fi sounding, deep with a crisp piezo edge to the highs. (from the horn) I used to use one occasionally for duo work. Actually pretty nice for jazz like stuff. But for Blues or R&R not a good thing really. Might be nice for home playing, but not gigging. The woofers are usually quite warm sounding without a horn. In a band mix the sound seems to disappear fast.

    A big chunk of the sound of a guitar amp is the speaker choice, and cab.

    Found this interesting

    I have run a Fender GDEC 3-30 into a Peavey SP-5XT PA speaker.
    It sounded ok.
    I was just experimenting.
    Not sure I'd want that as my only option.

    For many gigs (in another lifetime) I took a pair of Peavey floor wedges, took out the piezo horns, replaced the speakers with E120s... ran stereo, dang, huge, killer.

    but with the stock speakers and horns connected, was possibly the worst sound I’d heard in some time

    If you usea multi fx with cab sim it should sound fine. My Boss me 80 sounds great thru our PA when i use the recording out jack that kicks in the cab sim.

    I have an old square (not wedge) Klipsch PA cab I used to use as a 1x12 speaker cab, but to do so I had to pull the horn, cover the hole, and replace the woofer with a guitar speaker.
    Pretty boxy sounding little box so I also replaced the closed back with two panels of some scrap ply like the top and bottom panels on a combo.
    Eventually I got better cabs and it sits unused now.

    A PA speaker setup will IME sound like crap with a guitar amp designed for a guitar speaker, which the XD is.
    A modeler designed for a FRFR cab might be OK with a monitor, but a monitor might not even qualify as FRFR.

    The flip side is you can get a PA head to sound close to a guitar amp by running it through a guitar cab.
    Speakers are a huge part of guitar sound.

    Sounds like a recipe for a fizzy and boomy mess. VHT makes a nicely priced 1x12 and the speaker is pretty good.

    Thanks for the input!
    My thinking is if I am in pinch for a cabinet, I can grab a monitor and just repurpose the cabinet housing itself. Take out the PA speaker and horn, and put in a guitar speaker.
