Just click "File" and then "download as", choose the format of the spreadsheet and that's all.

It's the Sanitarium's spreadsheet if I am not mistaken, is just that I didn't have an address for it, you should download it to use it. It is a very accurate calculator.

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.

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

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 Assembly guide (generic dimensions):

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.

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.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.

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.

Just WoofersEtc is rather expensive you can get those amps cheaper elsewhere.

What's your budget.

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.

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.

1.2-1.5 cubes per sub. 33Hz at least I'd say.

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.

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 Assembly guide (generic dimensions): Let me know any questions.

Draw your box, does the port fire sideways?

Gross volume is meaningless figure for spec use, a brand new LMS-R 15" sub is $433.

Can you go a little deeper or wider, guessing this is a trunk car.
