You can run Torres on mac just download virtualbox and get a copy of windows. That's all you need.

Just ordered one for my wifes car, yes I know... She gotta start somewhere. I need a basic ported box for it. Its a d4 and will be running off a Kicker ZX 500.1 @ 2ohms. Need around 0.75cubes @32 hz. Trunk dimensions are not needed being this is a small ass box as it is and its going in a 2003 Buick park avenue so she has plenty of room for it AND groceries!
Here is a suggestion done on your specs:
Enclosure Specifications:
Fb = 32 Hz
Vb = 0.75 ft^3
External Height = 9.5 in
External Width = 21.25 in
External Depth = 14 in
Port Width = 1 1/2 in
Cut Sheet List:
* All Dimensions in Inches.
* Wood Thickness is 3/4 for all Parts.
External Enclosure Parts:
Front = 19 x 8
Back = 21 1/4 x 8
Left & Right Sides:
Side 1 = 12 1/2 x 8
Side 2 = 13 1/4 x 8
Top & Bottom = 21 1/4 x 14
L Port Internal Assembly Parts:
Front to Back = 11 x 8
Extension = 16 x 8
Extension 2 = 6 1/4 x 8
Assembly guide (generic dimensions):
Let me know any questions.

The RE calc is off.
For a side firing port:
Enclosure Specifications:
Fb = 32 Hz
Vb = 4.68 ft^3
External Height = 30 in
External Width = 30 in
External Depth = 16 in
Port Width = 14 1/2 in
Port Height = 5 in
Cut Sheet List:
* All Dimensions in Inches.
* Wood Thickness is 3/4 for all Parts.
External Enclosure Parts:
2 x Top & Bottom (3 parts) = 30 x 16
Left & Right Sides =
Side 1 = 22 3/4 x 14 1/2
Side 2 = 27 3/4 x 14 1/2
Front & Back = 30 x 27 3/4
L Port Internal Assembly Parts:
Side to Side = 23 1/2 x 14 1/2
Extension = 1 x 14 1/2

anybody else care to chime in with some helpful how to on porting my box ? i am really clueless as to what i should tune for to get the best overall sound out of my sub set up .
What is that you don't like about it's sound?
-
OP check this:
-
What I would like to know is why you are limited to those dimensions.
-
That's awesome Joe X
My only concern is......2 12" subs that are 12.5" each overall diameter = 25" + a 5" port width....means the subs would be right next to one another on top of the port.
The sketch is generic, they do fit very tightly one towads the front one towards the back.

So here is a suggestion:
Enclosure Specifications:
Fb = 32 Hz
Vb = 4.5 ft^3
External Height = 30 in
External Width = 30 in
External Depth = 16 in
Port Width = 5 in
Cut Sheet List:
* All Dimensions in Inches.
* Wood Thickness is 3/4 for all Parts.
External Enclosure Parts:
2 x Top & Bottom (3 parts) = 30 x 16
Left & Right Sides = 14 1/2 x 27 3/4
Front & Back = 30 x 27 3/4
L Port Internal Assembly Parts:
Top to Bottom = 22 3/4 x 14 1/2
Extension = 3 x 14 1/2
Assembly guide (generic dimensions):
Crossbraces are 1.5" diameter, let me know any questions.

What subs are going in that enclosure?
-
14'' h 17''d 32'' w --- port is 11 3/4'' h 3 1/2'' w but has a 1/2'' board in the midd of the port to split the sub up so like 1 1/2'' w on the port for each sub.... this is what he said.Measure the external dimensions as well as the port dimensions and then post those and people can tell you the real specs, having said that you don't want to use those prefab enclosures in most cases. Subs work best in enclosures designed specifically for them and solidly built.
14 x 32x 17 gives a gross internal volume of 3.42 less if there is a double baffle and to that you have to take away sub and port displacement, so NO 4 cubes net possible.
And you are not giving the centerline length of the port or the port parts length so can't calc tuning.

Thanks guys, helps a lot. Ill be sure to get a pic of the set up out as soon as i get it together.
Just WoofersEtc is rather expensive you can get those amps cheaper elsewhere.
-
What's your budget.
-
Sorry, these are swr-1042d type-r's.
2-500 rms
1500 peak.
Changed the above for 2 x SWR-1042D, hope you understand the kind of amp power you are dealing with, set the subsonic filter to 30-31 Hz.

In b4 45s are overrated.
You said it first!

Your port area is off and your net volume high, for your vehicle I would suggest the following if you can fit the small increase in external dimensions:
Enclosure Specifications:
Fb = 35 Hz
Vb = 2.24 ft^3
External Height = 17 in
External Width = 26 in
External Depth = 15 in
Port Width = 2 in
Cut Sheet List:
* All Dimensions in Inches.
* Wood Thickness is 3/4 for all Parts.
External Enclosure Parts:
Top & Bottom = 26 x 15
Left & Right Sides = 13 1/2 x 15 1/2
2x Front = 12 x 15 1/2
Back = 26 x 15 1/2
Shared Port Internal Assembly Parts:
2 x Front to Back = 12 1/2 x 15 1/2
2 x Extension = 9 1/4 x 15 1/2
Let me know any questions.

right on, is 1 cu ft each for 2 alpine type r 10's tuned to 31 hz a good place to start as far as box goes for that car? These are the subs available to me at the moment.
1.2-1.5 cubes per sub. 33Hz at least I'd say.
-
6 in would be ok, and yes net internal volume maximizes the way is drawn right now. You just need to figure out a seal off plan, will your back seats fold down?
OK, i figured that would be the reason for the front subs.. And Yes my seats will fold down.. Is there a way you could provide me a cut out sheet for the design you gave me?
I will consider some improvements, check calculations and then provide you a cutsheet by tomorrow.
-
Can you go a little deeper or wider, guessing this is a trunk car.
I could go 6" wider but I would like to keep my current dimensions instead of having to buy all new wood
Here is a suggestion, took the 6" wide and 1" deep to reach the spec, hope you can fit that:
Enclosure Specifications:
Fb = 36 Hz
Vb = 2.5 ft^3
External Height = 13.5 in
External Width = 36 in
External Depth = 17 in
Port Width = 3 1/2 in
Cut Sheet List:
* All Dimensions in Inches.
* Wood Thickness is 3/4 for all Parts.
External Enclosure Parts:
2 x Front & Back (3 parts) = 36 x 13 1/2
Left & Right Sides = 14 3/4 x 12
Top & Bottom = 36 x 14 3/4
L Port Internal Assembly Parts:
Front to Back = 11 1/4 x 12
Extension = 10 13/16 x 12

Draw your box, does the port fire sideways?
-
how much would i be looking at for a TC coil for it? im kinda bummed now that it seems this thing wont perform like it should. and 3.5 cu ft net im assuming?
Gross volume is meaningless figure for spec use, a brand new LMS-R 15" sub is $433.

You just don't have the space for 4 15s

Time for a new enclosure (2 12" xcon's)

Updated the sketch, extension is the length of the port after it turns. In this case is so small that it can be left out without causing a significant change in tuning.
