I have a PA mofo 15, And I can't seem to find its displacement. How's .25 ft^3 sound? reasonable?

prolly way to much, if you have the manual it will say in there. otherwise try to find the specs online. prolly around .1-.15

This is basic high school chemistry, duh!
Fill a tub with water... Measure the water amount, insert your object, and record the new water level.
Subtract the two, hello to your displacement...:crazy:
or you could contact the company...

I've looked online and in the manual, Yet no displacement. Maybe i will call the company.
But prolly not b/c I'm just that lazy. Yes, This is right folks. I AM that lazy.

Displacement as in Vd or how much space the subwoofer will take up in an enclosure?

At first I tried the water, But I couldnt figure the displacement from that its harder than it seems. So I contacted the manufacturer, via email. But now the sub doesnt work. Do you think the water messed it up?
