For fun heavy eq on the low end to play fullrange from 55hz. just to see how it sounds, must get the distortion down low down, extending high end a bit. and see if i can make a overhung coil so it can have a high xmax. in this video the coil of the contraption is almost out of the gap. resulting in weird sounding compressed low end. wonder what happens when you change it to overhung besides losing efficiency.
The gain down low or more the notch up high is a high shelf around 400hz -10 dB. so it sounds as if the low en d is gained 10 dB without driving my minidsp into clipping
