FI Q 12" box type question

[desiredfaith 0]

Alright right now i have a FI Q12" running 1000 RMS@ 1 ohm (with knob at 10% power)

thing hits harder then hell right now, in the past iv always used sealed boxes and when i got this one i got a ported to see what the hype was about

I want to get a sealed again but if i do will i lose those super deep lowes or is it the sub itself that makes them.

(basicly i want to know will i get the deep lowes with a sealed)
