    ported downfiring enclosure.

    is there anything you need to do different when designing a ported downfiring enclosure? I searched but did not find any answers regaurding ports.

    correct me if i'm wrong, but wouldn't the floor act as another port wall and affect tuning? increase the length of the port and lower the tuning frequency?

    Re: ported downfiring enclosure.

    could I put the L shaped port facing up and the sub down?

    Re: ported downfiring enclosure.

    So it does not matter if the subwoofer is mounted on the same side the Port side #2 is?

    I was not sure if that effected the tuning in any way.

    Not quite sure what you are asking... If you are asking is it okay to have the subs mounted on a different face than the port, then yes... that is okay.

    I used to believe always put the port on the same face as the woofer, and still pretty much believe this for an SQ system... For SPL/SQL i don't feel it is necessary.

    Re: ported downfiring enclosure.

    ok to clear up my question look at this link. http://www.reaudio.com/speaker_box/LPort_Box_Calc.html

    the back wall is where port wall 2 runs parallel with. I also want mount the subwoofer on the same wall.

    Re: ported downfiring enclosure.

    just remember that the closer the sub is to the opening of the port the more free air the sub is. i would go subs down and port back to get the most reflection possible.

    Re: ported downfiring enclosure.

    So with a L shaped port keep the port opening on the same side as the woofer?
