They recommend 80 liters net on 1K.

External Height = 20 in
External Width = 37 in
External Depth = 24 in
Port Width = 23 in

Ur dimensions are very similar to my current enclosure which i got with my p2s.. And im sure they will do much better in bigger enclosure cause they sound much lower with the trunk open..I was thinkin to make it at least 5cuft or more since they recommend 3.5 cuft for single fi q 12...
Yeah you can put them in 5 cubes net is just that I just went over your 34x16x20 if you have more tell me so and I will make it bigger no problem.
-
I did some modifications and I will be able to get 49.5 width and I also can make the box deeper if that would help.
With 49.5W and the slightly narrower port you get back your original net volume of 4 cubes per sub and about 35Hz tuning.
-
Joe, Quick question if I was to change the width from 51 to 48.5 and change depth from 22 to 22.625 and the volume is almost identical would the port need to change in depth?
Yes everything would change slightly, to preserve 35Hz the port would need to turn a bit sideways and a bit thinner, you would loose 0.3 cubic feet:
Enclosure Specifications:
Fb = 34.75 Hz
Vb = 8 ft^3
External Height = 20 in
External Width = 49.5 in
External Depth = 22.625 in
Port Width = 7 3/8 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) = 49 1/2 x 20
Left & Right Sides = 20 3/8 x 18 1/2
Top & Bottom = 49 1/2 x 20 3/8
Shared Port Internal Assembly Parts:
2 x Front to Back = 16 11/16 x 18 1/2
-
Here is a suggestion:
Enclosure Specifications:
Fb = 33 Hz
Vb = 6.7 ft^3
External Height = 14.5 in
External Width = 37 in
External Depth = 36 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) = 37 x 36
Left & Right Sides = 34 1/2 x 12 1/4
Front & Back = 37 x 12 1/4
Port Quantity and Dimensions:
Number of Ports = 3
Pipe Port Diameter = 6
Pipe Port Length = 27
Port area per cube is 12.6. Xmax is apparently high with these subs. Let me know any questions.
-
Well aeros on the side maybe, this can be done going a bit over your max dims:
Enclosure Specifications:
Fb = 30 Hz
Vb = 4 ft^3
External Height = 16 in
External Width = 34 in
External Depth = 23.5 in
Port Width = 4 1/4 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) = 34 x 16
Left & Right Sides = 21 1/4 x 14 1/2
Top & Bottom = 34 x 21 1/4
L Port Internal Assembly Parts:
Front to Back = 17 x 14 1/2
Extension = 14 x 14 1/2
-
Not saying a SA-10, just a 10", how about a SSD 10", that would still be cheaper than 2 SA-8s and can handle 1K no sweat.
-
If your port length is 14 then don't use 12.5", the external part of the port is just subtracted from displacement. BTW it seems nice at 12.5, just build accordingly.
-
Changed the above for a box for a single SA-8 let me know any questions.
EDIT: Maybe you should consider a 10". You have the space.
-
So here is a suggestion Subs up/port back:
Enclosure Specifications:
Fb = 34 Hz
Vb = 5 ft^3
External Height = 18 in
External Width = 38 in
External Depth = 20 in
Port Width = 4 1/4 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) = 38 x 20
Left & Right Sides =
Side 1 = 18 1/2 x 15 3/4
Side 2 = 19 1/4 x 15 3/4
Front = 33 x 15 3/4
Back = 38 x 15 3/4
L Port Internal Assembly Parts:
Front to Back = 14 1/4 x 15 3/4
Extension = 2 x 15 3/4
Assembly guide (generic dimensions):
Double baffle is recommended but not strictly necessary.
Let me know any changes, comments or questions.
-
1 1/4 up.

Okay sweet, thank you so much, and what do you mean ground pounder? what kind of sub is considered a ground pounder, and what is mine considered?
What I mean to say is to keep your expectations low, if you want some crazy flex you need mighty power and subs to match that master the low end like the RE XXX or the SSA XCON to name a couple. Your sub may be considered daily use sub, will get you a good thump and some flex but that's about it.
-
Ok so your sub is 600W RMS, so bear that in mind, here is a enclosure suggestion for it:
Enclosure Specifications:
Fb = 34 Hz
Vb = 1.75 ft^3
External Height = 15 in
External Width = 27 in
External Depth = 14 in
Port Width = 2 in
Cut Sheet List:
* All Dimensions in Inches.
* Wood Thickness is 3/4 for all Parts.
External Enclosure Parts:
Front = 24 1/4 x 13 1/2
Back = 27 x 13 1/2
Left & Right Sides:
Side 1 = 12 1/2 x 13 1/2
Side 2 = 13 1/4 x 13 1/2
Top & Bottom = 27 x 14
L Port Internal Assembly Parts:
Front to Back = 10 1/2 x 13 1/2
Extension = 16 3/4 x 13 1/2
Is not really a ground pounder sub either so expect some nice bottom end but not a lot of flex.
-
Okay so I have a jvc arsenal dual 4 ohm coils on a 700w rms arsenal amp and I need a box to hit the lows and make my car flex nicely! I don't do bass coms or anything I was thinking tuning around 34hz? I'm only 16 and its my first decent sound system and I saved for a while to buy it so please don't hate! I already know a lot of people have much better! Please help me design a box, I drive a 99 Audi a4 trunk is 36 wide 17 tall and 34 deep. Thanks in advance! (:
What would be the size of that sub, better the exact model of the amp and the sub if possible.

L Port Internal Assembly Parts:
Front to Back = 21 3/4 x 42 1/2
Assembly guide (generic dimensions):
Don't do the flush mount shown.
Any changes comments or questions, let me know.
-
I'm a little confused by the port. Like how and where the air will actually flow
Added a pic from another angle to see if that helps.
-
Post your max dims for the box. and amp model.
-
Could you take the top off so I can see what it looks like inside
Some bracing.. that's all:
-
So i was looking around at some different subs and i was thinking about swapping my AQ subs for Fi. Any thoughts about doing this?
DO IT. A no brainer!

If you post some max dims I could further help.
help with box design
in Subwoofers / Enclosures

Yes the size of the box biggest you can fit for a sub inside your trunk: height,width, depth so that I can post some plans for you.
