[QUOTE="Moe Lester, post: 848232, member: 551478"] not quite, the port displacement brings it closer to 2.66 cubic feet, and then after driver displacement you will come out with even less volume. The lower volume is also going to cause the tuning to be higher. Dont forget to factor in the 3/4" pieces of MDF required to make your port, they take up space too. First, figure out port length Then figure port displacement Add port displacement + driver displacement + net cu.ft. you are aiming for + bracing displacements if you are bracing it. That will give you the total amount of airspace required INSIDE of the box. [/QUOTE]
