When you build a subwoofer cabinet how do you account for the mass of the speaker in the volume measurements? If you were to calculate out a 4.5L box but then put in a giant sub wouldn't that reduce volume?

Yes, subtract the volume of the driver. Some sub manufacturers give it to you. Though I dunno how a giant sub could go into a 4.5L box. Giant subs usually take giant boxes where the volume of the driver is insignificant.

I figure 3L for our 12" driver, 5L for our 15" driver but in the box sizes our subs use it really doesn't make much difference. Changing the temp. 6-7 C makes more of a difference or changing the box Ql.


In smaller box sizes it can become a bigger factor.
