In practice, a speaker’s wattage is only needed for amplifier matching.Ī cranked 100-watt amplifier will blow up any speaker rated lower than 100 watts, and the stiffer cone, increased damping and wider voice coil, that might enable a speaker to cope with 100 watts, could compromise the tone and dynamics of a 15-watt amplifier. In contrast, a speaker’s power rating merely indicates its power handling and tells us nothing about loudness. An amplifier’s power rating provides a rough indication of its loudness potential.
