On the manual for my Denon DRA- 425 Says it supplies 50 watts per channel. Does this mean that mean each tweeter/woofer/Mid gets 50 watts or the entire speakers get 50 Watts of Power? I am confused. Also sorry if this is such a noobish question. If anyone else can explain impedance, Crossover frequency, nominal impedance, and sensitivity this would be greatly appreciated.
