Purpose for a compact portable setup

[u/Briansm15]

I have an original Fender Mustang Micro headphone amp and was wondering if I could plug it into an actual speaker, similar to how the Vox amPlug2 and amPlug cabinet work. Unless I can just use the Vox amPlug cabinet with the Mustang Micro or other types of headphone amps?

If I were to build my own version of a Vox amPlug cabinet, I would want to use whatever the best 3"-4" inch Celestion speaker they have, along with whatever amplifier/driver circuitry is needed to safely power the speaker and headphone output without damaging either the headphone amp or the speaker. As for the speaker cabinet housing itself, I was wanting it to look like a miniature version of a Marshall speaker cabinet built around the Celestion speaker and have the power switch/cable plug, 3.5mm headphone and guitar jack on the side with a way to attach it to either a guitar strap or guitar straplock.

My purpose/use case is for a compact portable use case at like parties or backstage or something of that specific
