    Too much port area?

    What happens if you have more than the recommended port area but its still tuned to the right frequency?

    Re: Too much port area?

    18.75ft^3 would work well with 300 sq. inches of port. Every box I build I use 16 sq. inches of port per cubic foot net volume.

    With 13.5 net I'd use 216, for a daily setup that is.

    bigger port usually means a higher peak in ur frequency responce which is better for spl but not so good daily...
