Sundown audio nightshade 4 or mtx jackhammer?
Is this a joke? I don't think the JH would outperform the NS by much, if at all. Considering the NS is a little north of a grand and the JH is around 10 -- I'm no financial genius, but it seems like the NS MIGHT just be the better buy. Plus the MTX weighs 400 lb because it's built for idiots with money. The NS actually tried to build a functional giant sub, so they used Neodymium magnets. It weighs <80 lb. If you're really looking for a giant sub check out incriminator. They have some 18's and 21's that are solid and not terribly expensive.
