I'm preparing to build an enclosure for the Adire Tempest driver using
Adire's plans called the "Adire Alignment". This will be a 7.56 cu
ft box with two 3" diameter ports. The sub is downfiring.

Redesign the box for vertical placement of the loudspeaker. You will
like having done this in 10 years. Just my opinion, ymmv.

I have all the plans and needed wood measurements, however, I have
concern about how to stuff the recommended 4 lbs of polyfill. By
filling the entire encolsure evenly with 4 lbs of polyfill, I'm
concerned that there is some risk that the polyfill will settle around
the back of the driver or into the port tubes.

Any suggestions about how to prevent this? Could I use some type of
screen material or perhaps an additional brace (with numberous holes)
placed above the subwoofer?

Gregs suggestion on how to keep the polyfill in place will still apply.

Thanks to all who have responded. I believe I will use a combination
of sticking the polyfill to the sides and perhaps using cords or twine
as a net above the driver and ports.

As far as mounting the driver for a vertical alignment, I'd like to
know more why I'd appreciate this design in 10 years. Unfortunately,
I have two toddlers who haven't learned to keep out of my
electronics. Having the sub mounted underneath would offer a bit more
protection than if it were side mounted.
