For the best sound quality, the subwoofer should be placed with the speaker facing out to the room, and the port should be away from a wall. Bass waves travel in all directions, but it's important to have the speaker facing your main listening area.
Where is the best place to put a port in a sub box?
Best acoustic coupling is accomplished when the port(s) are installed on the same side as the woofer(s). 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.
Does it matter where the port is on a subwoofer?
It should not really matter as long as you have plenty of open space in front of the port. In other words you do not want to place a rear ported sub or speaker right up against a wall.
How far should subwoofer port be from wall?
6-12 inches Additionally, a sub's close proximity to a flat wall can cause a harsh, rumbling, unpleasant sound. And if your subwoofer is a ported design (a subwoofer with an opening to allow airflow), you'll want to keep it twice the diameter of the port (typically 6-12 inches) away from a wall to allow airflow out of the port.
Which way should car subwoofer port face?
Facing the subwoofer upward while in the trunk, gives you big bass without consuming a lot of space. This direction offers crisp sound with a slight advantage to high frequencies and treble, and won't rattle loose parts in your vehicle as much.
How big should the port be on a sub box?
However, the port size is determined by the square footage of a subwoofer box. The optimal amount for this type of enclosure would be 16-20 inches deep, with an 18-inch depth being the most common. If the port is too large, it will actually decrease output and extension rather than increase them.

Is a bigger port better?
The size of your subwoofer enclosure is dependent on the cubic foot, not just the woofer. It's best to go deeper than wider. A more critical port means a deeper tuning frequency which means you can get more bass from a smaller enclosure.
How Far From wall is bass port?
Speakers should be at least 2-3 feet away from the nearest wall (especially if your speaker is in a corner). Many speakers have rear-facing bass ports. Positioning a rear bass port too close to the wall will reflect sound waves, resulting in time smearing.
