I've built 3 boxes for my old 15w3'* - all without screws. If the box can handle 2 -15 with 1000 watts then I think it works. I've built a box for my 10w7 and it is still completly sealed (hasn't blown apart) - no screws. I've built a box for a 18w3 in a *-10 - without screws. That setup has actually cracked his windshield and sucked and blown his roof in and out so bad that it is now dented in for good. If it can handle that kind of pressure then I think that it works.
I know it sounds crazy to do this - I was doubtful the first time too but don't say it will not work when no one has done it. I wouldn't even think to using crappy liquid nail or just normal wood glue to do this. You need a polyurethane glue that is actually going to laminate the two surfaces together. Yes you will need to have bar clamps or lots of weight to do this. Yes putting dadoes and rabbits will increase the gluing surface thus increasing the strength of the joint but this is not needed since it is greatly stronger then a joint with screws. Screws will actually weeken the joint in a MDF appiclation.
