box design help

[garrett30]

I am wanting to do a rebuild with my new AQ sdc2.5 15's and need a little help with designing a box. Anybody on the forum intersted in helping a fellow basshead out?

[garrett30]

I have 2 AQsdc2.5 15's and the dimensions are 38"Wx30"Dx17"H. I would like the tuning at 32hz and i have a 1999 ford contour.

Ok so the AQ SDC2.5 work best on 4-4.5 cuft per sub and 14-15 sqin/cuft so you are low, here is a design suggestion on your space:

Enclosure Specifications:

Fb = 32,351 Hz

Vb = 7,67 ft^3

Subwoofer Mounting = Flush Mounted

External Height = 17 in

External Width = 38 in

External Depth = 30 in

Port Width = 6 in

Cut List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

Front = 31 1/4 x 15 1/2

Front Internal = 30 1/2 x 15 1/2

Back = 38 x 15 1/2

Left & Right Sides:

Side 1 = 28 1/2 x 15 1/2

Side 2 = 27 3/4 x 15 1/2

Top & Bottom = 38 x 30

L Port Internal Assembly Parts:

Front to Back = 19 1/2 x 15 1/2

For your type of vehicle is recommended subs/ports in the same face front or rear firing so both should be tried.

Here is an assembly guide (generic dimensions):

for that sub you can tune higher.. try a tuning closer to 35-36 htz youll be alot happier and it will free up some room in your box

thats what i was thinking them subs like it at around 36-38.... i am currently building a box for these same subs but i got it tuned to around 35-36. right now i have them in a box thats tune to 39-40 its ok but im building a new one to tune lower. good subs by the way

what would i need to change on the box design above for it to be tuned around 35hz?

ive had up to 2k on these subs and they took it with no problem.. post a vid of the sound and see if someone could figure it out..not the best at diagnosing a problem without being there but someone could prolly give suggestions
