Is this woofer good for moving 13cu.ft. cabinet ?

I have a cabinet that is 13cu. ft. (Pretty big) Need to know what woofer or woofers to put in cabinets. I want to make it a dual woofer cabinet , but is this woofer the one to use ? what would be good for a 13cu. ft. cabinet , Dual app. ? This picture shows what I want to do. (Image not real) yet. Help !
Asked by: sounds
Actually this woofer would be ideal if you were only going to use one per cabinet. With two I would recommend the Peavey 18" Low Rider which is a perfect match for this volume as a pair.
