I gave up waiting for the Gallo amp and ordered a Hsu 500A (500w) subwoofer
amp with a 43 Hz crossover module. I had a 30-day moneyback period to
decide, and really like the thing. It's a SERIOUS amp and an ideal match for the
Ref 3s, which I'm driving with 12 wpc SET monoblocks (845 output tubes). The
500A costs $749 direct from Hsu, approx. $200 less than the Gallo sub amp.
Originally, I was using a Fosgate Audionics 100wpc amp with a Hsu electronic
crossover on the second voice coils, but this setup didn't have nearly the
authority of the 500-watter. Good luck, Dave
PS You need to break in those second voice coils just like the rest of the
speakers . Play 'em loud and hard.
