I reckon Barefaced cabs are at the pricey end of the small cab market if they are hand-built. Is there an official website?
The Eden EX-112 looks compact but Im not reading anyone recommending it.
I remember someone having a Hartke 4x10 that I liked the sound of but I def want to get a single 12". I have an Ampeg 2x10 but miss the bottom I can get from my old but tonne-weight Acoustic combo with 15" ported cab. I think the 12" should be an adequate and portable substitute.
In terms of volume produced, I had no idea about displacement etc. Will leave that to the experts but all advice is good advice. As said before, cost will decide the eventual choice but hopefully from this discussion and fellow opinions it will be an informed one.
