A Torres snap would let me see better, I really don't know how you figured out that design.

The box should spec at 14cuft@35Hz the subs displacement is not listed. As always port area per cube should be 12-16.

It's two subs Snowdrifter!!

It will sound tight but still on spec: Enclosure Specifications: Fb = 36.06 Hz Vb = 3.687 ft^3 Subwoofer Mounting = Flush Mounted External Height = 13 in External Width = 30.25 in External Depth = 26 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Front & Back (3 parts) = 30 1/4 x 13 Left & Right Sides = 23 3/4 x 11 1/2 Top & Bottom = 30 1/4 x 23 3/4 Port Quantity and Dimensions: Number of Ports = 3 Pipe Port Diameter = 4 Pipe Port Length = 18 1/4 As before top to bottom and front to back crossbracing applies.

4 cubes seems a bit large for a 12 don't you think? It says "port them"

Yes you can do ported very well on that space with 3 4" aero ports (flared), ports/subs in the same face front firing is suggested, take a look: Enclosure Specifications: Fb = 36.048 Hz Vb = 4.128 ft^3 External Height = 13 in External Width = 30.25 in External Depth = 28 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Front & Back (3 parts) = 30 1/4 x 13 Left & Right Sides = 25 3/4 x 11 1/2 Top & Bottom = 30 1/4 x 25 3/4 Port Quantity and Dimensions: Number of Ports = 3 Pipe Port Diameter = 4 Pipe Port Length = 16 Top to bottom and front to back crossbracing applies. Let me know any questions.

Better read this one: http://www.jlaudio.com/header/Support/Tutorials/Enclosure+Ports/Tutorial%3A+Enclosure+Ports/656168 The Torres is based on this document, the and correction applies only once.

Minimum recommended PA/Vb is 9 for aero ports, best way to know is using WinISD free software, Port Mach below 0.05 is best. Without telling which subs can't say.

Where did you read that? curious.

It's within spec but on the short side, 2.5 cubes minimum per sub 3.75 max, depends on the power you are driving those, for rated 3.75 is probably best if you are going to overdrive them then a smaller Vb is better, with space 3.2 per sub would probably be what i'd have aimed since subs hit the lows better with more airspace. Your configuration is not standard, so no sketch right now.. see if with some time I make some simple one for you later, if you want to give up some more depth let me know.

Ok so here is it port back (bottom center vent) subs up: Enclosure Specifications: Fb = 32.012 Hz Vb = 5.496 ft^3 Subwoofer Mounting = Flush Mounted External Height = 16 in External Width = 31 in External Depth = 32 in Port Width = 4 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Top & Bottom (3 parts) = 31 x 32 Left & Right Sides = 30 1/2 x 13 3/4 Front & Back = 31 x 13 3/4 L Port Internal Assembly Parts: 2 x Front to Back = 24 1/4 x 4 Top = 24 1/4 x 19 1/4 Or better you can go with aeroports (same box as above): Enclosure Specifications: Fb = 32.08 Hz Vb = 6.068 ft^3 Port Quantity and Dimensions: Number of Ports = 2 Pipe Port Diameter = 6 Pipe Port Length = 20

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?
