Is too much air space bad for subwoofers?

No, it will in fact increase output. A larger air space means more air to compress inside the box as the cone moves, which means less resistance on the cone, which means more cone movement allowed, which means more output (whew).

Does polyfill make a difference?

its not really that the sub thinks the box is bigger….it changes the acoustical properties of the enclosure. when you stuff any box full of fiberous material it slows the backwave. in doing so, you create better low-end frequency response.

Will a bigger box make subs louder?
