Im built a ported box for two JL10W5-D4 subs.
The specs on the speaker are:
Vas: 1.60 ^3
The box im building is 18*14*14 per chamber
IM using a Punch 800.2 to push them with about 200W to each.
The port dimensions it calls for are 3x10.75.
This port length seems kind of short to me for a 30-40hz tuned box?
Am i wrong here? What should the port dimensions be for a round port?
The box is already built so it dont have much room to play with for the length of the port.
