guitar cab with built in tube poweramp

[El Chiguete]

Has anyone ever made for themself a guitar cab with a built in tube poweramp? The idea behind it if to have a 4x12 cab but just use the top 2x12 and on the bottom part place a poweramp section, that way you would just plug the pedalboard or rack in to the cab and you are good to go!

I only found an old and rare amp that used something similar to my idea and is this. here is the picture and description:

So anyway, coming back to my initial thought, maybe even you could even use the speaker holes to make a cover to add knobs and switches of the poweramp section (Presence, boost, watt options, etc?).

Tech 21 makes the Power Engine for modelers but I would think that someone might of though of combining their favorite tube poweramp with a cab to use with there rack or pedalboard.

There are the Atomic Reactor 2X12 60W tube cabs.

Hey El, there are lots of variations on this theme, the main one I spose putting it all in one cab ala combo amps.  Some reasons you may not want to put a tube poweramp inside a speaker box (e.g. quad box) is microphonics (although may make desirable sounds ??), speaker cabs tend to get thrown around, I was always nicer to my Marshall head or my rack than to the cabs LoL and heat (probably no a great idea in a closed back cab). Also then you have to run power to the cab(s), like active speakers, it's a pain and watch out for ground loops.

I think R is right,doesn't sound like a good idea to me,a lot of vibration going on in there.
