i have four alpine type r 12's in two pre-fab boxes all facing up. the boxes are just undersized for the subs and the tuning is off... if i sell off all this and get two RE Audio SXx 12's in a custom ported box tuned @ 33hz. do you think i would be butting out a higher spl? and what about sq? opinions and comments greatly appreciated! thank you
