nahhhh this box is right around 20 with 120" of port. I know, not alot for 4 18's but its all i could do in this particular situation. The 300" port your thinkin of is on the box i used when i was running 2 18's.
I was wondering why the port is so short (length) for such a big box. Should not the port be much longer than that? Maybe it's tuned high like 50Hz or more?
