The sub im putting in it is a 12"
its a Fusion Jonah Lomu 12" ( FJL-1211)
My Store Ltd - FJL-1211 12" Sub Woofer- DVC 1300 watts (Powered by CubeCart)
1300watt DVC (4ohm each)
Its about 5 years old
From some research the guys that used these for comps etc ran up to 6cu foot enclosures.
No its not ideal but its going to be fun trying to get a 2.5cu foot enclosure in there.
Im toying with the idea of full fibreglass.
