16 Ohm

16 ohm refers to the electrical impedance rating of a guitar speaker or amplifier output. Impedance affects how efficiently power is transferred from the amp to the speaker and influences tone and volume. A 16-ohm speaker cabinet or output is less common than 8-ohm or 4-ohm options but can be used to match certain amps or to connect multiple cabinets in series or parallel. Matching impedance correctly is important to avoid damaging equipment and to ensure the best sound quality and performance from your gear.
