I got this box for free it is a Sony bass reflex porter box for 2 12's model xs-l120b5d. It looks like a well made box. Not sure if it would be good for my needs. Any input would be great. The only specs I could find on it was 32"wide 16"high 18" bottom depth and 15 1/4"top depth dont know anything about the port. All I know it's a round tube port
