Just got the plans is there a way of doubling the design for 2 X 12" (Faital Pro 12HP1020 neo woofers)cabinet? How would I start to modify this design. Any thoughts I was also thinking maybe 2 X 15"? I need it to run from say 60Hz-2.0kHz for 2 X 12 or 60Hz-1.0kHz for the 2 X 15" woofers.
Thanks, looking also for 12" WO as subs.
