I used this box design for my L5s. However I made a mistake when building. This box is supposed to be tuned to 35 hz. However I made the port about an inch too wide so it is tuned quite a bit higher than 35. It peaks at 47 so I figure its tuned to around 42. I like the box being tuned where it is now for comps but I am wanting to create a simple plug to lower the tuning for daily driving.

What would be a good frequency to tune two 15 inch l5s to for daily driving? I was thinking 32 hz.
Once I decide on a set tuning could someone please tell me how wide the port on the box needs to be for that tuning?
