highest output from two smaller subwoofers?

I believe you want each driver in it's own rear chanber, firing into the same front chamber, so it's like a mirror image? In that case the front volume figure sreten has given you needs to be doubled, and you tune the front section to the frequency as given. That could be accomplished by one or two or even three ports, it depends what diameter pipe you use.

Hi,

If the above is the case you need 3 15L chambers.
Two outside tuned to 33Hz, the centre one tuned to 80Hz.

/sreten.

Surely you mean 3x 30 litre chambers.

Hi, nope, the sim shown is for 2 drivers in a box, /sreten.

OK I thought it was for one.
