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).
