GRS 12PF-8 12" Paper Cone Foam Surround Woofer
Specs say 11.69" cutout diameter & 12" overall diameter. I don't see how this could be correct. What's the true cutout dimension?
Yes the cutout listed online is incorrect, the actual cutout for this woofer is 11.0625"

This speaker + Grs 8 paper cone in "woofer" air space 2.1 cu ft ?
I found these great cabinets this weekend at a yard sale.Drivers were bad. wanted to use this  12" which I already have 6 of and the  grs-8 paper cone which I own 2 of, in the same air space wired in parallel with the dayton 3way crossover set to 4ohms.question is my internal volume of the entire cabinet is 2.9 cu. ft. and the space after bracing and enclosing the "woofer"area is 2.079cu. ft. is that enough space for this 12" and it's little brother the 8" together for the low end? Thank you.
Unfortunately you never want to mix two different woofer sizes in the same airspace. There is no way to properly model this and the smaller of the two will always be fighting the pressure of the larger, plus there is no benefit in the long run anyway.

can this be used as a subwoofer and be loud with 80W?
This would not be ideal as a subwoofer with that much power. You would be better off using something like the DCS305-4 below.

how good or bad would this work in my tower that has 2.239 Ft3 even though the woofer optimum sealed volume is 2.92 ft.³? my tower has a 2 inch tweeter and a 4 inch mid range if that will effect anything .
Yes this will still work in that volume as long as it is sealed.
