Sundown SA's vs Nightshade on 2k

[Tim Lam]

Hey everyone, its been a while since i've posted on here.

anyways i am currently set up with 2 Sundown SA12's in a box ~4.4 cubes and tuned to 36hz(this was for my HDC3's originally but was too lazy to build another box plus it sounded fine to me)

but lately ive been thinking about getting a 15, and a nightshade to me seemed very appealing.

im running a crescedo bc2000d(inb4 you wont even move that sub)

here's my current set up. please watch the whole thing before you judge lol

if i switched from this to a nightshade 15, would I get overall louder(aside from frequency response differences)
