the 15 is the best sound solobaric, either the l7 or the l5 the only difference, is that the l5 requires less power, but has a weaker polymer cone (i think polopropalene is the right word for it) none the less, 2 cvr12s will smack with bass and sound better than the 15's *mind you not louder* but sound better, the solobaric series is more of a burp spl speaker. I know kicker subs like i know the back of my hand, a ported box with cvrs will sound deeper and more bass'ier and the cone excursion wont sound as tight as they do now. but a s15l5 will sound good with less power, and it will sound better in a ported box, my bro had 2 s15l7's in his frontier with a 1200.1 and that bitch was fucking loud, now he has 12 10" comp vrs with 3 500.1 rockford amps. just remember they are kickers, they dont necesarily need rms to sound good.


but hey what do i know
