It's $200 for a 4x12 cabinet, so it's not going to be the best. Hard to say without plugging in your amp and playing through it.
Are you saying you need 2 4x12 cabs to play in your praise band? I fear for the congregation. Do you normally not mic it because you don't have extra mic channels on the mixer, or you'd rather not? No one today needs a double stack; few acts that have them actually even have both top and bottom plugged in!
oh no, I don't need two stacks. that would be scary... this Vox cabinet is just a little smaller than the one I have now an it would fit in my car easier and be easier to load/unload because I'm usually loading/unloading by myself.
And also, I really like the Vox cab for it's looks...
So mainly, I want it for the convenience and for looks, but not if that means I have to sacrifice sound quality.
