are there any real accurate box building calculators? i have used torres, winisd, bassbox, re, etcetc. all of these calculators are roughly 7hz off in tuning. for instance, if i use torres and build a box "tuned to 37hz", tuning will actually end up being 29-30hz. anyone?

dont fucking call me out no0b, you have no clue what youre talking about. dont come here for advice and try and be a fucking toughguy when you get the advice you dont wanna hear.

downgrade to 12s and go ported!

thank you.....hm

wow youre right, i did forget to change the port height. i listen to alot of dubstep and metal. yesterday i build a big box alot like the design i gave you, except for a 12. im very happy with it.

how does one go about becoming one? haha

just get a new amp. hifonics brz2400.1d. cheap but better than mtx...

theres no way that amp does 2.2krms. no use getting it repaired. IMO mtx is stupid and overrated.

im interested in the new alpine type-r line to be honest...and i am an AB fan to the fullest.

this is what you want. you're underpowering the sub, so a bigger box should give you the best output. usually a smaller port area will sound a punchier for your metal and rock,

time to grab a new pair of xfls brah

check wiring.

i like the way you think.

nahhh, got the sub for free. this kid had this sitting in his back seat. Told me "you can have it bro, it's a no name sub with nothing on the dustcap. i'm getting a kenwood!"

lol me eiths brah

nubcake

im only giving it 600rms...

i'm not shunning your advice man, but everyone on here says "underpowering sub=bigger box" haha. i used to love building boxes, but now it just seems like such a chore, i dont wanna do it again.

Today I built a box for my 12" TC9 proto. The sub can supposedly it can handle up to 1500rms. It's dual 2 ohm (each coil is sitting at a constant 1.7ohm). The box is 2.2 cubes tuned to 34hz with 12 sq in of port per cube (14.5h x 18w x 24d). I'm only running 600rms to it via JBL monoblock @1ohm. It has no subsonic filter (guessing it's built in), lowpass is around 80, and gains were set with my DD-1. I built the box long, instead of wide, with sub and port on the front of the box. This is roughly what it looks like (and enjoy my artwork). When I play really loud, my sub starts bottoming out on some lower frequencies. I heard the coil bounce off the backplate a couple times, but got to the volume knob before it was too late. Also, some lower notes seem to have that "unloading" sound. Is this all happening because of there being too much airspace behind the cone of my woofer?

id rather go with a hifonics if i was tryna save a few bucks...
