Im making a box for my T1 soon. Its going to be 2.25 cu ft @ 32Hz. To make the box can I just use woodglue plus screws to hold it together then caulking on the inside for that airtight seal plus carpeting on the outside? is that pretty much it? and for the whole for the sub, do i just cut a circle then just screw the sub right in? or is there more to it?
