October 22, 200816 yr wait for jacob.......... if i had to guess going off my install it would be some where around 3 cubes ported on a single 15
October 22, 200816 yr They don't need alot of room - 2.5 cubes would be acceptable, most people use 3 cubes.
October 22, 200816 yr Author wow! i think thats what i been looking for...a 15" sub that dont need a big box
October 23, 200816 yr Yeah the nightshades dont need terribly large boxes. Jacob reccomended some guidelines for me for the 12" nightshade. I ended up doing 1.65 cubes tuned to 38 hertz with internal bracing and a triple baffle. Its absolutely incredible how well it does.
