Description

First I found in the woofer's original datasheet from the manufacture's website, that the min. recomended RMS power=2000W, the recomended freq. resp.=25-60Hz, and the 1-way linear excursion=17.5mm. After replacing the Xmax, recalculated the Vd. Then I tried out to simulate the recomended boxes from the datasheet. After this I had an idea to make Fb=20Hz, F3=25Hz vented box and optimize Xmax for 2000W, then I found out that if I increase the Vb a tiny bit, the F3 drops below 20 Hz.
