I have Max Dimensions of 16" High X 37" Wide X 30 Deep... Can someone come up with a design with drawings and cut sheets... I would like it to be as loud as possible and still have a slightly ok sound to it.... I will be running the subs with two IA 40.1's I will pay for design if need be... Thanks alot for your help...

Based on the info, they are recommending a

5.2 cubic foot box tuned to 43 Hz.

Based on the info, they are recommending a5.2 cubic foot box tuned to 30 or 31 Hz.

So would the box be 5.2 cubic feet with 104 Sq in of port @ 18" Deep

 

[mcsoul 10+ year member]

No 5.2 plus 104 @ 18" or is that what you meant?

Let me run the numbers, looks like 3 4" areos will be

easiest to build. The tune I came up with was actually

43Hz
