HDC3 18 box, 5.5 cubes ok?

You should be fine, you also have plenty of power behind it, so a smaller box in your application should balance out.

I agree he has plenty of power, but 4 net for an 18 seems like it's pushing it.

I mean, the port for my mag was nearly a foot. I'm assuming for an 18 it would be at least that. So, 4.5 cubes - driver displacement.

I just don't see the 18" sounding decent at all in that little of airspace. Unless he he going for an all out SPL application, in which area I have no expertise whatsoever.

It'll be fine, Sleepy_jr has 10.25 net, before all displacements and only giving 2k a piece and his shit slams, and drops low.

For 2 18's? That is over a foot more net than he has man. That's about 5 net each, which is fine. He has 4.
