Glossary term

Headroom

The margin between a reference operating level and a limiting level. In amplifier planning, an allowance for signal peaks above the chosen reference level helps avoid exceeding the amplifier’s available output.

Amplifiers & preamps

How much amplifier power do your speakers need?

Amplifier power depends on speaker sensitivity, listening distance, required level and allowance for peaks. A calculation can show how those inputs change demand, but it cannot certify a speaker pairing. Check the amplifier’s supported load and rating conditions, the speaker’s limits, and the intended installation before turning an estimate into an equipment choice.
