1.5 to 2.5 cubic feet net internal (per sub).

The SSA ICON ot the Fi SSD are top choices, the box would be much smaller.

So here is a design suggestion for a ported box, subs firing upwards, port front or back centered: Enclosure Specifications: Fb = 32.026 Hz Vb = 16.622 ft^3 Subwoofer Mounting = Flush Mounted External Height = 29 in External Width = 42 in External Depth = 32 in Port Width = 8 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Top & Bottom (3 parts) = 42 x 32 Left & Right Sides = 30 1/2 x 26 3/4 Front & Back = 42 x 26 3/4 L Port Internal Assembly Parts: 2 x Front to Back = 17 x 26 3/4 Let me know any questions. EDIT: Note that this is on your max dims but need to be at least 3 cuft per sub, seems to me that these are space wasters, I would probably look into other stuff also.

Post the maximum dims you have available and yes you can go with aero ports in some cases.

So here is a design suggestion, barely will meet the mfr spec of 3.5 cubic feet per sub, subs firing upwards, port front or back on either side (to save airspace): Enclosure Specifications: Fb = 34.075 Hz Vb = 7.086 ft^3 Subwoofer Mounting = Flush Mounted External Height = 15.75 in External Width = 37 in External Depth = 32 in Port Width = 6 1/2 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Top & Bottom (3 parts) = 37 x 32 Left & Right Sides = 30 1/2 x 13 1/2 Front & Back = 37 x 13 1/2 L Port Internal Assembly Parts: Front to Back = 17 x 13 1/2 2 rod two inch diameter dowels top to bottom need to be put near the center and between the subs, their displacement has been considered. Let me know any questions.

Need to know what sub or subs are you going to use, assume you want ported box?

If you don't have the time to research further the the suggestion I gave you will be acceptable for a daily setup, if you had more space I would use it, you are at about 3.3 cubic feet per sub. These are 1,5KW rms subs with high peak to rms ratio so crossbraces are necessary as indicated in the design post, if you came by more specific infos like t/s parameters that would help to confirm the performance of the design would be great.

NP any questions let me know.

Well this would be a suggestion avoiding heavily any port noise: Enclosure Specifications: Fb = 36 Hz Vb = 2.247 ft^3 Subwoofer Mounting = Flush Mounted External Height = 19 in External Width = 21.75 in External Depth = 18 in Port Width = 2 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front = 19 x 17 1/2 Front Internal = 17 1/2 x 17 1/2 Back = 21 3/4 x 17 1/2 Left & Right Sides: Side 1 = 16 1/2 x 17 1/2 Side 2 = 17 1/4 x 17 1/2 Top & Bottom = 21 3/4 x 18 L Port Internal Assembly Parts: Front to Back = 14 1/2 x 17 1/2 Extension = 8 1/2 x 17 1/2 Let me know any comments/questions.

List the maximum dims you can fit, and the vehicle you are going to install this.

Anything? Here is a suggestion: Enclosure Specifications: Fb = 33.062 Hz Vb = 1.992 ft^3 Subwoofer Mounting = Front Mounted External Height = 16 in External Width = 29.75 in External Depth = 14 in Port Width = 2 1/4 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front = 26 3/4 x 14 1/2 Back = 29 3/4 x 14 1/2 Left & Right Sides: Side 1 = 12 1/2 x 14 1/2 Side 2 = 13 1/4 x 14 1/2 Top & Bottom = 29 3/4 x 14 L Port Internal Assembly Parts: Front to Back = 10 1/4 x 14 1/2 Extension = 20 1/2 x 14 1/2 Just make sure it fits your car.

Modified the my original post, the design can work but I would strongly recommend to call or email these guys up for specs, about 3.3 cubes net per sub will be in the short side but is all you got.

Reliable specs for those subs are not available, I am guessing it will be about 3.2-3.8 cubes net per sub. Maybe email these guys.. proceed on guessed specs is not a good idea but I just think that you won't be able to fit them.

On those maximum dims you won't fit them, also there are VFL comp, extreme etc.. specific model?

6 inches instead of 3 will be alright.

Remember that's net internal the ported box will be bigger. If you use the Torres you are good to go if not post your maximum dims and I will suggest you something.

If you wish you can add just a couple of inches. with some care you can just place the 3 inches part as well. Proceed as you wish and let me know, I will tell you the effects of what you did.

Also they need 1.75 cubic feet each minimum for sealed, are you sure you can meet the spec?? Also would be interesting to know the spec of the enclosure you put the REs in.. that could be the problem with them, you have good enough amplification, don't know about your installation.

Sure you don't want to consider some other subs??

If it bothers you to cut such small piece of wood you can cut it longer, you will be tuned a bit lower, let me know how long you want to cut it and I will tell you how lower you will be tuned to. Just a few inches only please to prevent running into some other issue.

Tuned to 45Hz? if you are going with a prefab check that it's spec of the box is about right for the subs themselves.

This one is just right, your volume is within recommendation. Going top to bottom will lead to vent area ratio issues.

What 12" subs are you going to use? Your original port can work.

Your first design can work, you can make a simpler thing but whatever, what I don't know is how you calculated that box, Pioneer subs (many of them) work in rather small volumes. and also why the mini pics?

To choose subwoofers you start by getting the maximum dims of the box you can fit..and forget about the lanzar!
