Bronze Member Username: ThumprmsDaltonUSA Post Number: 34 Registered: May-04 | thanks glass, is it possible to buy a prefab box and drill a hole in it for a port? For example:could i buy a 2.50 cu ft box, drill a hole for a 4'' pvc pipe. put the port in and tune it to 32 Hz? if so what would the length of the port need to be? |

If you could, remember that you'd have to compensate since that 2.5 will be gross volume, any length you add to the port will subtract from the net volume of the box. Use the calculator on www.bcae1.com to find out what length you'll need. |
