When creating an enclosure and the specs say for an ideal box it needs 1 cubic feet sealed, does that mean I need to create an enclosure that is larger than 1 cubic feet so that when the woofer displacement is subtraced, it'll be left with 1 cubic feet?

 

Usually....read the fine print...I've seen a few that include the speaker displacement.

It's a good idea to run a program with the published specs. Box size is a trade-off between good transient response + higher power handling (smaller), and better low frequency extension + less power (larger).

I read a survey that said that the average consumer prefers a box with a Q of around 1.0, which is a bit on the small side in my opinion.

I think a lot of recommended box sizes are also weighted towards the small size to entice buyers into believing they can fit more subs. That may be the "ideal" box size for the manufacturer...

 

If the specs list the speaker displacement, then I guess it's not included?
