The issue is a little complex when discussing audio frequency modulated currents. Voice coil speakers use alternating electric current in copper coils in close proximity to the speaker magnets to create the mechanical motion of the speaker cone. Audio modulated AC current in any coil produces frequency dependent reactance and impedance not simple 8 ohm DC resistance that might be inferred by the speaker specification. The accuracy of overall sound reproduction is the ability of the amplifier to overcome the reactance and impedance across the audio spectrum otherwise sound distortion is introduced. There is also the issue of electrical resonance and the amplifier needs to be able to dampen such. In general all modern amplifier designs effectively deal with these issues unless you’re an electronics hobbyist building your own amp.
Amplifier current vrs watts; why is current more important?
Lately when talking to knowledgeable people in the audio industry I’ve been hearing how current delivery is more important than watts in determining weather an amplifier will drive a speaker.
So what exactly is current and how does it effect speaker performance? How can a amplifier rated at 150 watts into 8 ohms vs one rated at 400 watts into 8 ohms be a better match for a hard to drive speaker?
