I had a widebody 1X12 combo for awhile and that thing sounded HUGE. They have the MC90 and a 3/4 closed back, just like the matching 1X12 extension cab. I noticed the 23" combo and matching cab have a more open back, like 3/4 open. I guess that gives you a bigger sound from the smaller cab but do you lose any of that tight bottom/bass projection?
