Check how well an amplifier's power matches a speaker's rating.
Speaker power ratings should sit above amplifier power so clean transients stay inside what the speaker can handle. Undersizing a speaker for its amplifier invites clipping and damage, so the headroom margin is a safety decision.

Headroom = 10 x log10(speaker watts / amp watts)
