15 inch american bass xfl or 12

[taynelgar]

So I can't decide on which sub to get. Whichever one I get well be running off a hifonics glx.1400 at 1 ohm at 1400 rms. One is the American bass xfl 15 in a 4 cubic for box tuned to 32Hz. Or a 12 inch american bass xfl in a 2 cubic foot box tuned to 32Hz. I mostly listen to rap, dubstep, and trap music. I want it to be as loud as possible. But I have heard that 12's hit higher notes and 15's hit lower notes and are louder but hit slower and can be behind. What do you guys think? I guess the most important part for me is being the loudest with full range.

Not true. Both subs can hit whatever notes the box can produce

^^^ to add on to that

the only advantage of the 15 would "possibly" be playing a little bit lower and louder

My DC Level 3 15 dug to about 23-24hz with AUTHORITY.

All my single 12 setups tap out around 27-28hz before they run outta juice

not a total dealbreaker but from my experience, 15's play a tad bit lower

but as far as everything else, you could make a 15 just as accurate and tight as a 8

all in the box and sub/port orientation

Okay. The 15 it is
