Questions about System Power Amps

What's the difference between a system power amp and a stereo power amp?

System power amps are generally designed for full-range speaker systems and handle a wider range of impedances, while stereo amps are optimized for two-channel applications like home audio.

Why is impedance matching so important with system power amps?

Mismatching impedance can lead to reduced power output, increased distortion, and potential damage to the amplifier or speakers.

What does 'damping factor' tell me about a system power amp?

A higher damping factor indicates better control over the speaker cone, resulting in tighter bass response and improved transient performance.
