Well, first off.... there is no L-shaped "type" port. Ports end up being L-shaped because port length needs to be long to get desired port frequency. That type of port is called a slot port by the way. The next thing is that 1 3" port is no where near enough for those 2 12's. They should each have atleast a 4" port if not 2 3" ports. When you are doing ports, they have to be a certain lenth... you cant just cut a few ports at 10" and call it a day. My advice is to download Winisd (it is a free box buidling program) and mess around with it. If you have room in the box you have now, you could add a port(s) and make them the length Winisd says. This will actually help these subs get louder because right now, they are probably being restricted with that 3" port. Also... in most cases, there will not be any loudness difference between a slot port or a aero(circle) port.... if the port area is the same.
