No it won’t work, too flexible. If this is the direction you want to go I suggest Googling Sonosubs. You should also consider Marty sub enclosure or just a sealed enclosure which will be much smaller. By your question I’m guessing you have very little knowledge on subwoofer building (don’t worry I’m not much ahead of you) so I suggest going with an enclosure designed specifically for the Ultimax, there are lots and they will all get you evicted.
