    shorter is tuning higher and longer is tuning lower. assuming the box stays the same net volume, but it will change a little if you make the port longer the sub has less space to use and the port shorter it has more room.

    So, if I go to a smaller box, tuned to 30 hz my power handling will go up and tuning will be more daily correct?

    Re: Quick question on ports

    yeh smaller boxes are more peaky or have a narrow freq response, but since your wanting to do spl it should be fine. kinda hard to get a good spl and daily box out of one box. say for example a good burp box would be like 3cubes at 40hz and a good daily would be 4cubes at 30hz. then you could do in the middle and 3.5 at 35hz which would be good for both imo
