Can I buy or have built for a reasonable price an Iso box to hold a speaker cab and mic? How large should the box be in relation to the cab?

Hey VTgreen
I think you're looking for something like this ?

It's not cheap though. About $500 if you follow the link to the manufactures page..

I read the review, and with a 20watt Mesa Boogie cranked, the owner says it was TOO LOUD outside the box. What is the point then?
If you are looking for complete isolation of a guitar amp, you either need a correctly built iso room or box, built with the same principles as a floating room. Mass-Air-Mass, TWO LEAF assembly with one leaf decoupled. However, this would NOT be portable, although you could mount it on wheels, and the size depends on the size of the speaker box, and or how much "air" you want in the sound. Look at it this way. An iso box is simply a small "booth", built with the SAME isolation qualitys....i.e. BOX within a BOX, with each shell having a SEALED access panel or doors. The inner box must "float" on resiliant connections(either Neoprene suspension mechanisms, such as pads that the INTERIOR box sits on, or suspended via springs or Risc iso clips. For the INTERIOR shell(box) I would use ONE layer of 3/4" MDF and ONE layer 5/8" OSB, and on the EXTERIOR shell, I would use TWO layers of 1/2" MDF with a layer of 3/4" OSB sandwiched between them. I would leave an airgap of 2", filled with BATT type insulation, and line the inside of the interior box with 2" rigid fiberglass. This would be EXTREMELY HEAVY. But the reality is......
THAT'S WHAT IT TAKES!
if you want Marshall AMP type volume that is isolated.
The alternative is an electronic amp output dampener, or an amp simulator direct to the board. Although I've heard these don't sound REALLY like the real thing.
You could actually build this with a speaker mounted in a baffle as part of the inner box, just like the one shown in the link. That way it is always ready to go, and you can drive it with different amps. It would make it smaller too, as you would not have to accomodate the actual guitar amp, which if it has the amp/speaker box as a single unit, would prevent access to the amp controls. This way, you can run the amp speaker output to a reversed XLR(don't use 1/4" jacks, they leak) for the built in speaker, and another regular XLR for a built in Mic(use an SM-57. This would also eliminate the need for access panels or doors, although personally, I would make an access in the top for adusting the Mic for different Mic'ing axis positions. Remember to seal any penetration for wires from the exterior box jacks, through the interior shell for the mic and speaker. And also, since the speaker would be mounted on a baffle, I would also suspend this baffle via a rubber perimeter seal or suspension springs, and mount the mic on an isolation clip.
If you are interested in this design, I will post a drawing in plan, and vertical sections as soon as I fix my other computer(it has my Autocad on it and is fried at the moment) and also I can fabricate it too! Although, I don't know where you are located, and this would have to be PICKED UP, as shipping would be rediculous, and it would be EXPENSIVE, as this is the same as building a "booth". OR......if you are interested, I can also draw a complete set of plans and a cutting bill as that is what I do for a living, although I would have to charge for it, as it takes time and plotting. PM me if you are interested.
