It is early for me to give a detailed review of this item as I just got it 3 days ago, however I will share what was my thought process when I chose this cabinet and what I think of it so far.
I wanted a cabinet that can sound great for live application while playing mostly metal, I wanted it to be portable without sacrificing tone and I wanted it to be suitable of recording metal at home.
The cabinet certainly sounds big, it pushes air in your face due to it's closed back and delivers a great punch for crushing metal rhythm chugs. I did not expect that from a 212 (expecting less punch), however I am glad i went with this option as for me it sounds as powerful as a 4x12.
Regarding the size, it has about 30 Kg's, fits on the back of a car, can be carried by one person and also comes with wheels - this ticks the box for me the portability part.
Overall, happy with the purchase so far, maybe a 1x12 would have been enough for me (thinking that Petrucci uses a 1x12 on stage!), however it's good to have some extra punch in the back of my pocket as I don't know how my needs will change.
