Ordered sixteen F4 FeONIC audio drivers today. The Hull-based company have been really patient with all my questions relating to their technology, and so I hope their patience has paid off with today’s order. Annoyingly, they are no longer producing the F110 amplifiers; however, with my earlier bulk purchase of the Omnivox. I have ten that I could use (if in the end I don’t use my Omnivox supply). Probably I will purchase some other appropriate amps, or have them made up for me.
