Hi there,

I need to build new boxes for my subs. T\S params says I should go for 1cu of internal vol. My problem is, how would I calculate how much the speaker itself displaces, not being uniform and measurable, and I'm not going to drop it into a bath of water and measure the change.

Thanks

best way is to look at manufactureres specs, if they are not there, you can calculate the total cubic mass of the subs. Now this number would be much higher than the real displacement, but it would give you the idea.

Just find the formula to find the volume of a culinder and do the rest of the math. It is a complex equation tho.

if it doesnt list in specs u could email or call and ask.

Thanks lads. Don't remember seeing the displacement on the specs sheet, I'll have to root it out tonight.
