The midbass on the Max Ext mode is not that much lower, and I gotta think having the ability to get that extra sound/feel from 16-25 is important too.
I think Im gonna stick with 1 port open, EQ1, and 0.7. Im no subwoofer expert at all
Here's a graph showing EQ1
Keep in mind that the meter isn't too accurate the lower you measure.
Note the hump ~16hz due to the boost from eq1
