    Hi,

    I built a subwoofer based on this woofer W5-1138SMF, Put into an existing cabinet is about 7.0litres, and the port diameter is 2″ dia and 4″ length flare both ends. I seem to get chuffing at a higher level.

    1. Is the port dimensions adequate or need to be longer?

    2. DO I need to improve Internal reinforcement to improve the Bass response?

     

    thanks.
