Default Need input on this box design

I was thinking about building a new box. It's for a single 15" HD3. Here is a picture of the box with the dimensions. Now with those specs, anyone have an idea what the tuning frequency would be and how many ^3ft I would have? Also, 18"H is about an inch too high. I was thinking reducing by and inch in height and adding an inch in length. For example:



Back- 31.75" x 17""

Sides x2- 17" x 15.5"

Front baffle- 28" x 15.5"

Front in- 26.5" x 15.5"

Port x2- 13.75" x 15.5"

Top x2- 31.75" x 17.5"

Bottom- 31.75" x 17.5"



Also, is 90 inches of port too much or not enough?

As your picture is drawn you have around 3.2cf net volume and 49.5sq in of port tuned to around 36hz. Tuning will shift slightly with sub displacement. Where did you get 90in of port from?

I would highly recommend 33 hz, but SOME people here, not naming anyone, would disagree.

Really, that's it? Damn. I went with what that gave me, 4.3^3 and 90" of port. I'm new to all this so excuse my noobness.

My current box is about 3.8^3 and 32hz

Anyway, I'm trying to get over 4^3 after displacement tuned to 36HZ with dimensions of 17"H x 30"-35"L x 16"-18"D
Guess that design isn't going to work.

You could do 4.0cf @ 37hz with 46.5sq in of port within your max dimensions.

Aeroports would help.

For 4.0ft^3 net a single 6" aero would be fine.

you mean anyone who has actually run an AQ sub and isn't following some stupid trend and wants a box that plays music? You sure are an expert on AQ subs and box building all the sudden.
