2 15's Setup 2400watts. updated

The port caculator

http://www.carstereo.com/help/Articles.cfm?id=31

and other online calculators use the xmax in the calculations PURELY for the purpose of determining how much port area there should be.

Tuning freq is dependent on box ONLY, not the driver.

Port area for this box should be about 120+ in^2...

If you want me to, I will draw up plans for you. Free of course.

Just to back up your work or to work off of.

You will love these subs if you get them in the right box...

And I would recommend 30 htz for tuning.

My draw ups look like this (i like doing it all by hand)

And just for fun here is my box build log if you wanna look at it (took only two days to build this box: one day cuts and one day assemble and paint):

..

ye if u could:) but i still need the subs facing up and the port facing back in the middle and keep the measurements. 19" deep and tall 44" wide 25" long from back seat. heres tha new plan

[RobClay 20]

i got the front peice drawn. both side peices. top and bottom peices too gotta get a half a sheet of mdf to finish. i dont like using a hand skillsaw cuz it can messup easier and make it even a little off.. any tips to help keep it straight? if not im going to try to use one of my friends dad's table saw

Look at the pics of my box build. That is the best method. Those cuts we made were soooo straight. I'd recommend doing it like that

like clamp a yard stick beside the cut line and cut beside that to make sure it stays straight? i get what ur talkin bout

[nick_19 1]

Here. My specs are flawless... trust me.

I did all the math 3 times. By hand, no online calculators...

I took my time to do this for you, so trust me, it's right.

I can also draw up cuts for ya if you want.

I did a 3 inch port, then 6 inch combined in order to keep the math the same... otherwise it would get too complicated.

I couldn't get exactly 30 htz for tuning, but I got right under it.

Does this look good for you?

3.7515 ft^3 net per chamber

29.79 htz tuning freq

Yeah, but longer than a yardstick.

thanx man:D not many people would do that.. one question and ye it looks good ill go with this design. what is that number by the 19 on the left side of the drawing?

[nick_19 1]

The height!

Lol.

I'll draw you out some cuts and stuff if you'll use this plan.

The outside numbers are the outer dimensions.

Use a table saw, makes life a lot easier, especially with a good fence and extension table for the sheet

nah lol i ment what does the number say:P i can hardly see it

[nick_19 1]

oh 17.5 lol

that is inside dimension

Edited September 10, 2008 by nick_19

[RobClay 20]

oh 17.5 lol

that is inside dimension

o haha aiight the rest of the measurements are 10.75, 23.5, 17.3, 17.5, 44, 19, and 25.. tell if their all correct i just put them in random order

[nick_19 1]

yupp.

but that one 17.3 is a 17.5

I'll draw you up a cut sheet when i get time...

classes are kickin my butt.

i'll try to get them done by late tomoro night

aight here we go

put it together like i showed w/ the joints.

tips:

put together the two sets of two port pieces together w/ screws and glue b4 you screw them onto the box. It makes a funky angle that is hard to get to w/ your drill.

put together the box in the order i did w/ my box... i find that to be the easiest: put it all together on the 'bottom' of the box, then put the top on.

i'd recommend taking another 'top' piece and put it on top of the top to make a double baffle.

any questions, just ask me.

Gross-11.08

Gross per chamber-4.16

Tuning-29.79

Net per chamber-3.75

wow man. thanx for all the help and all that this is gonna help me alot. and all the tips. ill probably start tomorow. or sometime soon. ill keep you updated on tha pics and progress:)

but i really do appreciate your help, (sorry if i keep sayin it over and over again haha)

[nick_19 1]

Lol it's all good.

And I check this topic everyday, so if you got any questions, just ask me.

You should have minimal flex w/ two baffles. If you have extra room, you can double up on any side. You cannot do internal braces, because that would throw the airspace and tuning off. If you decide to double up a side, just add the sheet on the outside of the box. Like put it together w/ the pieces I listed, then take the measurements of the outside and make the extra pieces. These subs are only 600 RMS a piece, and I think single .75 will work great, but doubling always helps if you can!

Pics are always great!
