MACnonsence6 Posted May 4, 2011 Report Share Posted May 4, 2011 (edited) instead of people saying build another box or w.e id like to just stay on topic please. i have a shitty ported box with one re se 12 its slot ported and tuned to really high like high 40s. the box is a duel box and i have one of the holes borded off im thinking about adding an areo port to where the hole is to lower my tuning what do u guys think wanting to add a 3"x8" long port as far as cost i have no money if i did i would have built the box from the start im not talking about cutting the box just the piece of wood thats covering the whole how do i find out what my tuning would be after adding that port Edited May 4, 2011 by hifonics10 Quote I picked up an MTX Sw1212 powered subwoofer today. This thing sounds amazing. 130 watts, 12" woofer with a passive 12" woofer tuned to 27 hz. Moving the pictures on the walls and my girl got wet from the bass when i showed her haha.

spl4life Posted May 4, 2011 Report Share Posted May 4, 2011 i agree with everybody else... answer is no... im gna say rebuild.. but you dont wna hear that... just adding another port.. throws off your tuning... unless your very very VERY careful with calculations... but like i said... easier to jus rebuild... but if your stubborn and refuse to rebuild... heres what you "could" try cut the box and make it sealed first(making it a single sealed 12).... calculate total volume... figure out tuning for an external areo port... i would say thats the easiest thing you could do...

Skullz Posted May 4, 2011 Report Share Posted May 4, 2011 I know you don't want to spend money and i certainly don't like recommending it but get some 3/4" particle board to make a new box with as it only cost $20 a sheet since your budget is on the small to non-existent side.

(other then rebuilding a box)i could just put a bigger bored to cover both the slot port and the other hole and go aero no cuz its gona add the port volume into the equation... you said its a box for 2 12s... im guessing port in the middle? if so... then the port volume is shared with both sides of the enlosure if you seal it off... which is gona throw off you tuning again... thats why i said cut the whole box in half.. and seal it... take a pic of your box and post it up here... ill try to expain...
