my JBL Power subs pound pretty nicely. They are louder than a 12 SE in 2.0 @ 32 hz, 2 10 Compvrs 3.0 @ 34 hz and 2 10 L5s sealed. I know the 12s would pound way harder and would eat those lows like cookies. Im not sure if theres any of the old model left but if there is you will get a good deal on them. If not just get the new model - black with silver JBL logo.
