I know this sounds kind of stupid, but I have to convince my friend, what wins, 2 old school 12" cerwin vega strokers, or 2 L7 15's with everything being the same.
if i was choosing a sub between the two because i have watched a few videos on relam of excursion with people using the solobarics and when pushed hard it doesnt look pretty (uneven from corner to corner) I think cerwin vega strokers will definately hold up against the solobarics in spl and they would be my choice between the two
