which sub?

[garfa]

hi all,
well i have a delimmer on my hands, my CV ported sub just isnt doing it for me. so i think its time to upgrade a little.
the 2 subs i am looking at currently are
nakamichi sp-wd1200d
kenwood kfc-xw1202dvc
infinity perfect 12vq
o2 ow12
and finally i am sort of considering the kicker s12l7 (read: solo baric)
i know its sort of like having the completly different ends of the spectrum withthe nak and the kicker, but how badly will the kicker fair against the nak sub in terms of SQ? and what about the kicker Vs the nak in spl? how badly will the nak get its arse kicked?
mostly i want more low rumble that my current CV isnt putting out.
i know the kick will almost punch my heart from my chest with its rather brute force but i dont want to loose too much SQ.
cheers, garth.
(this is such a load of shit, but anyways...)
