Recommended Amplifier Power

We recommend an amplifier with a power rating of ten to one hundred fifty watts per channel for optimum performance. Outdoor speakers typically require more power than indoor speakers. The outdoor environment is usually noisier and has less reflective surfaces to make the system sound louder. Therefore, the use of a higher power amplifier is recommended.

Ironically, most speakers are not damaged by large amplifiers but by small amplifiers. When playing the loudspeaker at higher volumes, a small amplifier will run out of power very quickly. When an amplifier runs out of power it creates damaging “clipping” distortion. A large amplifier will play at the same volume without causing this distortion.

If the plan requires connecting two RS6 speakers on one amplifier channel, an amplifier rated to drive a 4-ohm load of thirty watts to three hundred watts, is recommended. If you use two RS6’s on one channel and the amplifier is not rated for driving a 4-ohm load, the amplifier will run out of power more easily and could damage the speakers.

See the section “Operation” for more information about clipping distortion.
