Does it matter where the port is in a sub box?

If this is not possible, installing ports on the side or back of the enclosure are good alternatives. Do not block the opening of any port(s) and always position multiple ports on the same side of the enclosure. For optimum performance, keep the port one vent-diameter away from the back and sides of the enclosure.

What happens if subwoofer port is too small?

Do subs hit harder in a ported box?

Air flowing through the port adds to the boom. Another reason ported subs hit so hard and deep is that the air flowing in and out of the port creates an audio effect like that made by a whistle or blowing across the mouth of a bottle, and that tone adds to and strengthens the note the cone plays.

Do subs hit harder facing up or down?

Registered. The closer a wall, floor, seat, etc. are to the face of the subwoofer, the louder it will be. This is due to the fact that the sound waves bounce off of the wall, or whatever it may be, and go throughout the cab in more than one direction.

How big should the port be on a sub box?

16 square inches of port area per cubic foot of box volume, make the port 18-20 inches deep. The port is tuned to the box volume, not the subs. This generally tunes the box to the upper 30Hz area, with the vehicle transfer function extending the frequency another 10-12Hz or so.

How much bass does a ported subwoofer box produce?

Ported boxes have another set of challenges. The rate at which the bass rolls off on the lower frequencies is 24 dB/octave. This means they will limit the lower frequencies the enclosure can produce twice as fast as a sealed enclosure.

Why do you need a port for a subwoofer?

A ported subwoofer uses the port to direct some of that rear sound to combine with the front sound, increasing the bass. If you were to mount those speakers in a ported enclosure, the bass would probably overwhelm the other frequencies, making it all sound muddy and indistinct.
