To be noted
Thanks to our linear inductance device, the low-pass crossover is easy to manage.
On this measurement, we compare the raw frequency response and with a 2nd order low-pass set at 3200Hz.
Furthermore, the cone break-up doesn't creates long dragging and sound coloration.
As a consequence, for PA, it should be possible to use this Lom120_vPA in full-band.
(An active high-pass at 100Hz is advised to increase power handling).
