i know i just posted a similar topic but came across another option. Thinking 2 15" BL's in team toxic bass box, 1 18" BTL in team toxic bass box, or 2 18" BL's in a standard ported wall. Cant decide because i have no personal experience with the subs and just tryin to figure out whats gonna move the most air. Also i know there are alot of variables but does any one have rough numbers of the increase in db's and air movement from a team toxic bass box vs. a standard ported box
