Recommended Amplifier
Although there is no single correct answer to the question of which amplifier to select, we can offer some simple suggestions. The table in the following pages shows two different options and gives recommended power ratings along with examples of possible choices of models. One option is to maximize speaker performance, giving priority to sound quality, while the other gives priority to using your speakers in a safe manner. The former will give better sound, but increases the risk of speaker damage from signals received in an uncontrolled environment. The latter may increase the probability of signals from the amplifier being clipped. But if you can ensure the signals from the amplifier will not be clipped, it reduces the chance of damage to your speakers.
Although the table in the following pages shows only recommended values for matching speakers and amplifiers, you should also consider the sound pressure level needed when selecting an amplifier. Lower sound pressure level requirements allow you to use amplifiers with lower power ratings. Using identical amplifiers can be beneficial as it allows for greater sonic consistency, and can simplify maintenance and inventory. When using multiple loudspeaker types simultaneously, or driving speakers in
Regardless of which of the above options you select, it is impossible to eliminate the possibility of speaker damage caused by factors such as microphone feedback, aggressive EQ, continuously clipped signals from amplifiers, processors, and mixers, and sine waves played back for extensive lengths of time. As such the recommendations listed here are not a guarantee of
