Hello! Im new to the forum...kinda. ive been living off of everyone heres help for a while now, and decided it was probably time to make an account instead of just sniping the forums haha.
Anyways, before everyone starts flaming me saying "just do sealed/ported, bp ***** etc" i know the differences, i know what i want and i want a 4th order...i had one for a single 12 oldschool fosgate that put out 300 watts and sounded like 600 with an excellent frequency range!
So now ive bought 2 alpine 12s, 2 mrp m500 amps and have unlimited mdf to work with, i just cant seem to get my measurements to produce what i want.
Id made a box last week but the ports were 4.25" wide x 22" long and it had little efficiency below 50hz, but destroyed everything above that!
Id just like help building one that will have a nice rumble around 31hz with good range. Ive tried winISD and i guess im too illiterate to understand it fully... Ive got 15"h x 32" w x 29" L to work with...i know its doable, im just having a hard time understanding port widths and stuff... I guess it has the same effect if it was short and wide as if it were thin and long? Im not really understanding it... If someone could explain it to me i would be so greatful!!
Thanks in advance!
