Ok folks, I am going to go with 2 12's in a ported box hopefully sooner rather than later ( not sure on subs just yet ) I am going to get a custom ported box made most likely around 4 ft^3 tuned around 32-35 hz. Now most port boxes I see with 2 subs have the port on the right side of the box. Will it make any difference if the port is in the middle of the box in between the subs and they share the chamber? Also what would be the difference in each sub having it's own chamber and port vs sharing a chamber and 1 port?

 

A properly tuned box can have the port almost any where and any shape. There is no difference between sharing and not sharing a port between drivers in a properly tuned box.



Note: it is super easy to slap a box together without tuning it in the design phase and you may just get what you pay for at a budget shop.
