Do the surrounds really need much power


I'm in the process of upgrading amps and wondering if the surround channels really need as much power as the mains and center? There isn't as much information going back there and the speakers are smaller. It seems logical that less power is really needed.

I would say its not about bandwidth as much as dynamic range.  All the special effects are sent to surround channels and can be QUITE dynamic.  Explosions, doors thudding closed, etc.  You need significant power to support all these noises they stick in the surround channels.

Yes. Surround sound speakers require a power source to be functional. Wired speakers use a long cable to connect to the receiver/amplifier (power source). Wireless speakers use a shorter AC power cable (mirroring that of a small appliance), batteries, or are charged before use cupcake 2048
