Having part of the back removed does not make you lose any lowend. I run my OS 2x12 with the back 1/3 open and it solved the problem you are having. It makes the lowend sound clearer and more full. There seems to be this bogus belief that if your 2x12 isn't fully sealed then you lose your lowend and your amp won't sound tight.
I had the same problem, muddy, congested and just ugly sounding. Removed partial back insert and the cab just opened up. Tight, clear and thunderous room filling low end.
he did not say 1/3 open, he said open all together. lets make this very clear if you're going to make comparisons
i also said it will change the projection of the cabinet - quoted by you saying "room filling" - if the user lives in an appartment and does not want it to be openly projected then the result will be an unwanted side effect.
Yes, but I read it as he wants to "convert it to a semi-open back". Then asked if "opening it up" would solve his problem. I think you then interpreted that as totally removing the back. But I don't believe that was his intention.
But you're right in that totally removing the back with lose lowend, and partially removing the back with disperse the lowend. But it will also clear up the lowend and actually make the sound coming from cab sound bigger. In the end, it makes notes and chords clearer and eliminates the mud from so much lowend bouncing around in a small confined space.
Dispersion is an important factor as you mentioned though. Does the OP want a straight and directional sound, or a wide, full sound?
