I've got a pair of BX8As for my studio and they're just awesome! Have incredible bass response and overall frequency range, not to mention the low-self noise and the lack of fatigue when listening to them for long periods of time.
They are pretty good with a Pam 510 amplifier from 1981. (why i use Pam 510 from 1981? i can decide what freq should be high and what should be low, that way i can better hear all freq and eq the best way)
