2 18" HAVOCS what size boxes do they like

[animalbmx1 0]

Im really looking at getting a pair of these to run off my kx2500.1. I can't really find info on box specs though. Does 14-16cuft tuned to 30hz sound to be right.

I own one, have it sealed at ~4 cu ft. 14-16 sounds entirely too big, also according to all the calculators I've seen, the EBP shows it to prefer sealed rather than ported boxes. Good Luck
