Question about changing tuning of enclosure

[Jbarrera93]

Enclosure Specifications:

Fb = 35 Hz
Vb = 5 ft^3

External Height = 18.5 in
External Width = 38 in
External Depth = 21 in

Port Width = 4 7/8 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 21

Left & Right Sides = 19 1/2 x 16 1/4

2x Front = 16 9/16 x 16 1/4

Back = 38 x 16 1/4

Shared Port Internal Assembly Parts:

2 x Front to Back = 17 1/16 x 16 1/4
2 x Extension = 2 13/16 x 16 1/4


Assembly guide (generic dimensions):

This is the enclosure I am currently using, I was wondering if it would be possible to drop the tuning down to 32hz with this design. Pretty much asking what needs to change to lower the tuning.

Longer port

You could try to extend the port out

[MACnonsence6]

easyest way to lower tuning is less woofer dissplacement so reverece mounting might lower it a little bit

Front to back longer? or extension?

[oldsoundguy]

Extend. You cant make the front to back longer as you would be too close to the back wall. Extend each side equal. I cant tell you how much though. Maybe someone else how has the program can.

[Jbarrera93]

okay, thanks for the input.

[oldsoundguy]

I meant to say cant make the front to back longer. I edited my post above.

[Jbarrera93]

Okay, I messaged Joe X he's the one who gave me the design. So when I get a response from him I will post here.
