sa8v2 areo port question

[conkay]

Im building a box for a sa8v2. My final specs will be .6 tuned to 35hz. Heres the question. With aero ports I'm kinda limited to port area. For this enclosure size I can either run a 3in port with a 7sq" of port area or 4in with 12in. Any input?

Build a slot ported instead, here is a box from a previous request that basically meets your spec:

Enclosure Specifications:

Fb = 35 Hz
Vb = 0.64 ft^3

External Height = 10 in
External Width = 19.5 in
External Depth = 14 in

Port Width = 1 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) = 19 1/2 x 10

Left & Right Sides = 11 3/4 x 8 1/2

Top & Bottom = 19 1/2 x 11 3/4

L Port Internal Assembly Parts:

Front to Back = 10 3/8 x 8 1/2
Extension = 14 1/2 x 8 1/2
Extension 2 = 6 3/8 x 8 1/2

Assembly guide (generic dimensions):

An aero port based SA-8v2 box meeting your spec would likely require running a partially external port to work so not neat at all.
