I just bought a sub and the specs say that it needs a 1 cu. ft. box. I
would think that the company would allow for the space that the driver
takes up in the box. Is this a proper assumption.

Also, when I mount my driver should I cut away the carpet that is glued
to the box? In a 1 cu. ft. box should I bother with coating the inside
with a sound deadening spray?

"I just bought a sub and the specs say that it needs a 1 cu. ft. box. I

No. But most subs will have a spec sheet that'll tell you what the basket's
displacement is so you can take that into account when building the box.

"Also, when I mount my driver should I cut away the carpet that is glued to
the box?"

Yes.

"In a 1 cu. ft. box should I bother with coating the inside with a sound
deadening spray?"

I've never used a spray, so I can't comment on that. I've always had
excellent luck with polyfill stuffing.

No. There will be volume specification of the driver for different
mounting positions (above or below surface, facing out or facing in).

Cut away the carpet so it doesn't bend the sub's basket between the
screws. A thin rubber gasket or a thin cured layer of silicone gasket
on the box works well. Many gaskets creep under high pressure so
re-tighten the screws a day or two after installing.

I haven't tried any kind of spray but you need something to prevent
echoes of the midrange that can get past a crossover.

I need to know why the sound deadening is to be done (spray, polyfil etc).
Since I assume that the box is used to increase the bass effect.
