Sealed box - shared chamber vs dual chamber

[I Like Waffle]

Is there a real difference in performance or output between a shared chamber and seperate chamber box for 2 12"s? Im building one tommorow and i cant decide which to pick

[thegreatestpenn]

the divider can serve as a brace so separate chamber can be stronger in that sense. I usually do common chamber on all of my boxes though for making wiring easier

I've allways built separate chammbers for each sub. That why if have trouble from one sub it's easier to know which one it is & if you do buld one chamber its better SQ if you invert one sub to work against the other.

Yes, there is a difference. Which works better is dependent on the box design.
