Recommended Amplifier Power
For satisfactory performance, we recom- mend an amplifier with a power rating of 10 to 100 watts for the DS6.3; 10 to 150 watts for the DS6.5 and the DS6.7. Curiously, most speakers are not damaged by large amplifiers but by small amplifiers. If your system is playing loudly, a small
amplifier will run out of power very quick- ly. When an amplifier runs out of power it creates damaging “clipping” distortion. A large amplifier will play at the same vol- ume without distorting. See the section on operating the speakers for more informa- tion about clipping distortion.
