>A 12" sub is around 40% more surface area than a 10" and a 15" is just over 100% more or double. So more or less two 10's is sort of like one 15. Four 8" is like one 15". Six 6 inch woofers is like one 15".
But only if they have the same motor.
Long-throw sub-woofer motors have xmax exceeding 20mm one-way; while 6-8" woofers often go only 5mm so it can be more like one 15" sub matches the output of 24 6" woofers.
>The only trick you have is that corner placement will give you an extra 6 db compared to wall placement...often this is at the expense of problematic modal problems.
Sure, although you can equalize that back to flat in the frequency domain.
