Hi,
guys my first attempt in making a subwoofer.
The Technical Side of the SUB
Ported
BOX VOLUME 68L
PORTS 3X 3inch X 25inch (this keeps the port noise below 17m/sec even at 300W)
Group Delay ~ <20msec at 20 Hz
F3 26Hz
Sealed
F3 - 40hz
Otc 0.626
The box is built such that it can also be used as sealed with all the ports closed.
regards

looks great ,good job.but try to keep the stuffing away from the ends of the ports. If it is fibreglass it will get blown all over your living space. And could affect port action.
Besides, several people here have shown that stuffing reduces bass output.
