Daniel Casado, director of engineering for McCauley P.A. Manufacturing USA, made a trip to Vancouver to guest lecture PAVI students on the new M421 subwoofer design.

The M421 incorporates four 21” long-excursion neodymium motor transducers with 6” voice coils, continuous power handling capacity in excess of 12,000 watts (24,000 watts instantaneous peak) and a maximum peak output of 155 dB SPL (at 1 meter).

"I'm really happy I came to Vancouver to teach at PAVI. The students impressed me with their questions and we had a very interactive class. I have taught at other schools in the States and I don’t often see this enthusiasm."
