    @opulentone – For the enclosure, try vented/Chebychev.

    Then, you can go to the box and play with the tuning. I usually have to cycle between adjusting the filter I put on (I always filter the low end to help on when it reaches X-Max), changing signal to match a power wattage that does not go over the max excursion line, then back to box or vent to adjust the vent tuning or the box tuning, etc. You basically rotate between all of them finding equilibrium. Then, up at the top, you cycle between showing the following graphs:

    Transfer Function Magnitude – trying to make the response curve decently flat, figure out your 3dB down point, etc.

    SPL – just to see curve and estimated dB output

    Cone excursion (keep it under the line for the driver; this is effected with the filter for the low end and the wattage in the signal tab)

    Rear Port Air Velocity (you have to tune the vent to get this value to around 17m/s)
