box tuning Help

[Mr. Loki]

If you need more info just ask, but I am having a problem that needs fixed asap.

height: 13.5 width: 44 depth: 26 = 7.231 internal volume before displacement

I am looking to tune it at 40hz

I used winisd, and other programs and they all say 4inches wide by 24 inches in height will make it 40hz, but thats just a 4x24inch cut out, no length in port nothing?

4x12 says 3.51 length?

It just doesnt sound right to me?

[Mr. Loki]

alot of views and no help...I know it sounds dumb and perhaps has an easy fix, but I dont know it...

I am not sure but I think 4 inches is the diameter of a round port. So you need 24 inches length of 4 inch ports.

[Mr. Loki]

naw I put in slot port, an it says 4 inches wide by 24 inches height would be 0 inches length and that doesnt sound right at all to me.
