I have 4 GNX124 in a 5 cubic foot box. For **** and giggles, i'm thinking about porting the box. My question is what port diameter and length of port would i use if I put in 2 ports?....thanks

    now the first thing is you want to make sure you can port the enclosure. second ported enclosures are bigger in cubic air space for the restoring force of the cone now the diameter and length of the port are both used in the tuning of the box like 32hz or 35hz what ever is recomened.
    if the box is too small add so cotton fill to make the sub think the box is bigger.

    more ports are there for one reason only and that is to give the same tuning but also so get rid of port noise and they are called low mock ports.

    i hope this helps
