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...//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

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?
