dc level 4 xls box help


Recommended Posts

You have 46,5 inches wide , 5 ports 4 inches in diameter are 20 inches, 26,5 inches for the subwoofers, i think that properly placed everything can fit with some effort.. can't think of anything else anyways.

Sorry man but i dont understand that at all. What i mean is If i put the 15's in the front with cone faceing the back of my seats. and try to put the ports on the top. you said 19" long ports even though there is 24" the subs will be right in the middle. and they would hit them. so i dont even think its possible to get 19" ports into the box without hitting the subs

If using 4" aeros consider this, port ends up:

Enclosure Specifications:

Fb = 33,2 Hz

Vb = 7,001 ft^3

Subwoofer Mounting = Flush Mounted

External Height = 24 in

External Width = 48 in

External Depth = 15 in

Cut List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

2 x Front & Back (3 parts) = 48 x 24

Left & Right Sides = 12 3/4 x 22 1/2

Top & Bottom = 48 x 12 3/4

Port Quantity and Dimensions:

Number of Ports = 5

Aero Port Diameter = 4

Aero Port Length = 19

A double layer baffle is used which helps, additional bracing may be required.

What program are you using?

the fewer ports you can manage, the better. less turbulence. box designing is more than throwing some random numbers up on a calc..

Just say no to Ground Pounder Customs.

More box builds

some cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches!

I'm with captain stupid.

yeah im just going to have to use 6" aeros. i mean thats the only way.

In that case you could do as follows, ports are still top mounted:

Enclosure Specifications:

Fb = 33,236 Hz

Vb = 6,447 ft^3

Subwoofer Mounting = Flush Mounted

External Height = 24 in

External Width = 48 in

External Depth = 14,5 in

Cut List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

2 x Front & Back (3 parts) = 48 x 24

Left & Right Sides = 12 1/4 x 22 1/2

Top & Bottom = 48 x 12 1/4

Port Quantity and Dimensions:

Number of Ports = 2

Aero Port Diameter = 6

Aero Port Length = 17

Try to install the ports far from each other an from the walls. The design calls for flush mounted subs, it's a good idea to perform it due to the way they are going to be installed.

Also note that some (mainly front to back) crossbracing would be beneficial.
