sub enclosure volume question

[SiGSR]

When they say a sub is reccomened for this so-so amount of sealed box volume; do I just look for a enclosure with just the recommended volume or do I have to compensate in the volume of the sub as well in my calculation.

Say I have a sealed box that is 1.25 cubic feet already, and the sub demands for 1.25 cubic feet. Am I fine, or do I have to compensate for the subwoofers volume and find an even bigger box.

It seems like an idiotic and simple issue, but I'm new to this whole stereo thing.

you should be fine...

I dont think you need to compensate for the sub as long as you get the box at the reccommended space. How would you know how much air space the sub occupies?

That's the problem I hope I won't have to face. The only real way I've found to find volume of an odd shape item is to dip in a tank of water... lol.

Thanks for the fast responses.

Generally the manufacturer will tell you the volume which the sub occupies, but since the sub's volume is small relative to the 1.25 cu. ft. enclosure, and sealed box volumes are very flexible, a 1.25 cu. ft. enclosure should be fine. If you are really worried, you can add some polyfill stuffing to the box to make the sub *think* it is in a slightly larger enclosure to make up for the airspace the sub will occupy. But personally, I would just go with the 1.25 cu. ft. enclosure.
