i am in the process of building compact reflex kick / bass box, it is 80 litres and the driver i am using is a pd 154, what length and width should the single tube port be in order to get a solid kick within the following frequencys 80hz to 250hz or does it need any length at all ? or how efficient would it be if it was a sealed box ? any advice would help not familiar with winisd etc so let me know thanks
80-250hz is not much of bass but more like midbass. Most of the kick drum is 60hz and octaves below and higher. But if you want a port that will work in 80liters then give me a sec and I will tell you the port length.
