Default Can a 2" x 4" port be done as...

a number of 1/2" x 3/4"deep holes so that the total volume of the smaller holes combined equals the same volume as a 2" x 4" port. (.206L or .007 ft3)?

Pretend the -3db is 50hz for the box and driver combo.

Any sonic penalties? Port noise?

Thanks

If you're asking about using multiple small ports vs. one large port, the effect is that port Q will be lower because of the greater peripheral surface area.
