i think you were unhappy with your last box because that box is tuned at around 50hz

make sure you have enough room with the hole cut out b/c i dont think u will...and honestly, after looking at their specs, i would run this sub sealed

alright i want some plans to thinking of building a ported box because i think it would be easyer to get the speakers in and out of insted of the plans i have already. it is for 3 solo x 18s and i will be running 3 autotek 4000.1 i want something that i can compete in spl and be used for a daily driver

any help is greatly needed

here are my dimentions

this is what pete came up with(4th order)

to fit in here

oh maybe thats why the bass sounds like crap. If you have time would you be able to design me a better box around 36-40hz? im not sure what would be good for techno and rap music maybe you can choose a propper hz tuning for me.

Thanks a bunch man! Just what I need, keep up the good work. I'm trying to learn that sketchup now myself, i like what it can do. How do you do it so fast?

thanks, very good job

amatt Thanks man I do have a couple of questions tho. On the port calculations I can achieve the same tuning hz by having less area and a shorter port. Whats the advantage or disadvantage of this. And is the port length measured to the top of the outside of the box? I do plan on having a double layer 1.5" thick top plate. Does this mean that my first port lentgh needs to be .75" longer..? What is the end correction spec? And on the subs specs you think that the sub would work better sealed..? Is this because of my limited size or is this because of the specs period? I've seen these subs on youtube with 2.5c.f. and they look like they absolutly slammmmm. As far as making the box wider your right I will need to make it at least 13.25 wide and more like 13.5. Thanks again for all your help.

smaller port=more turbulance=port noise....general rule of thumb is 12-16sq" of port area/cubic foot of box.

the port is measured straigt down the middle of the port like in the pic below (this is not a pic of your port...just an example)

just take .75" of the length of wood for L2, so instead of 5.875 make it 5.125"...or u could just leave it, probably wont make that much of a difference

end correction is half of the ports width, in your case 1.125"....this is added on to the port length variable in the tuning calculation, but you can ignore it really...

there are two reasons i think u should go sealed. 1) the manufacture only has plans for sealed boxes on their site 2) the qts of that sub is like .52 if i remember correctly....and with that high of a qts, it means it should perform better in sealed enclosures.

I made a box on the RE audio box builder program and came up with this.

Width 30"

Height 18"

depth 17"

port width 3"

port length 22.5

tuning freq 36.1hz

does this come up the same on your calculator? Or is this a bad sized box for my sub?

earthquake dbxi-15D 15" sub.

^^^

did u see the one i posted....its 2.55cubes tuned at about 35hz...might be a little small but give it a shot

With school and work I haven't had time to sit down and design a box for my Q that is coming... wanna see what you can do?

Car: Grand Prix (trunk car)

Sub: 15" Q Dual 2ohm - gonna throw 1200wrms at it.

Dimensions: here is a photo posted earlier of what fits in the trunk

if I get time to do it I'll post back, but then again it's always fun seeing what someone else comes up with and comparing =) thanks bro.
