Help with Ported Box Dimensions Etc

[urbana4]

New to the forum here and just got an audison voce 5.1k to run my avk6 components and Hertz HX300D 12" sub but looking for someone to give me some box dimensions and port size for a ported box for this thing. I listen to alot of rock and hip-hop so want it clean but hit pretty good too.

Nice stuff, Hertz suggests 1.25 cubic feet @ 40Hz, if you want specific dims need to know what's your car, also that amp is too powerful for the sub, you need to enable the subsonic filter and keep your gains in check. Also you may suggest alternative specs for the box.

How do I enable the subsonic filter?

I know amp is big for sub, I have the 12" DVC at 2-ohm, for tuning gains I have the DD-1 so should be ok. As far as box I talked to Yusuf at electro media, he said 2.0 cu ft ported tuned at 35hz I'm just not sure of dimensions etc to make that happen.

Ok so what vehicle is this going in and what are the maximum dims for the box.. sure about 2cu.ft?

[urbana4]

06 a4. Yeah he said 2.0 cu ft

Ok the driver has a displacement of 0,1 cubes, here's the box:

Enclosure Specifications:

Fb = 33.2 Hz

Vb = 1.5 ft^3

External Height = 14 in

External Width = 27 in

External Depth = 13 in

Port Width = 1 3/4 in

Cut Sheet List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

Front & Back = 27 x 14

Left & Right Sides = 11 1/2 x 12 1/2

Top & Bottom = 27 x 11 1/2

L Port Internal Assembly Parts:

Front to Back = 9 3/4 x 12 1/2

Extension = 17 x 12 1/2

The subsonic (or infrasonic) filter is set on the amplifier set it to 30 Hz.
