I was reading in The Absolute Sound magazine about power amps and came across this,
Another way that manufacturers exaggerate power ratings is by not specifying the power bandwidth. This term describes the frequency range over which a power amplifier can deliver the power out put specified. A power amplifier delivering 200W only at 1kHz is far less powerful than one that can deliver 200W over the full audio bandwidth of 20Hz-20kHz, the general range of human hearing. You’ll often see mass-market audio/video receivers with power-output ratings specified only at 1kHz, or from 50Hz to 20kHz. Further, stereo power am plifiers can deliver more power when only one channel is driven-look for the words “both chan nels driven.” The maximum power output should also be specified at a certain maximum level of distortion.
After reading this I looked up my M700’s specs and found exactly that. The power rating is at 1 kHz and there is no power bandwidth rating. Does anyone know why? What am I missing. How can I know what power bandwidth my amps are?
