Dual 15" Common Chamber Enclosure:

[Duran 387]

Okay, it's about time to put my Sundown SAZ 3000D to good use, I've finally settled on subs, they are Crossfire XP 15's that I will get for super cheap and they are high quality subwoofers: http://crossfirecaraudio.com/htdoc/cf_m01_product_05_xs.asp#. I have some dimensions worked out, I used the SSA Box Calculator and I believe it's all worked out, I just need help bringing the calculator measurements to life! http://www.soundsolutionsaudio.com/home/in...int=1&page=

Can someone give me a hand on how to put that on paper so I can build it?

There is no dimensions there.

You could use this one and it will make a cut sheet.

My bad. Fixed it!

No you didn't. It is going to clear the fields every time the page is loaded.

Okay, using 3/4" MDF

Height=16"

Width=36

Depth=30

You dont really have enough room to do 15"s ported.

They only need 6 cubes between them, and I plugged all that in and it was 7.1 cubes after displacement.

I have a BMF 15" sitting in my room right now, this is a big step above a BMF though, this is more closely related to an Fi BTL

ye, just saying they are some good subs

sounds like you didnt account for wood thickness. Max internal volume is 6.22 ft^3 and that doesnt include port or driver displacement.

Weird, cause the calculator subtracts driver, and port displacement, and accounts for wood thickness.

never mind I miss read your dimensions I read 23 instead of 30.

What were you trying to tune it to?

Relatively low, 30-32 Hz. It's a sedan, no no matter what it will mostly peak at 40-50 Hz.

If I am seeing things correctly now and Im not to tired you may have problems on placement of the subs.

Heres what I got. The only real place to mount them is on the top of the box subs up port back situation if they fit there.

[Duran 387]

Do you think it will be a problem putting them on the top? With only 29.5" to work with?

[NB50 206]

You might be able to stagger them. Id have to check the subs dimensions and maybe break out the sketchup.

That's what I was thinking too. Thanks for all your help man, I appreciate it!

No Problem. It looks like you should be able to stagger them. Those circles in the pic are 16" in diameter cause I couldnt find the outer diameter spec on the website so I just went with 16 to be safe.

That looks damn good! I was still doing it on Sketchup, you are quick!

[NB50 206]

That wasnt even done all the way kinda halfassed IMO.

[NB50 206]

Almost forgot, you should add some bracing to the box also.

HAHA, yeah. That's a must!

[Duran 387]

Bump! Does this box sound good to everyone else?
