[QUOTE="audioholic, post: 4535482, member: 549629"] Basically, heat makes the voice coil's impedance increase. Higher impedance means less output from the amplifier. In other words, you do not gain the same amount of increase in output going from 1,000 watts to 1,001 watts as you would going from 1 watt to 2 watts. Heat decreases efficiency, basically. So... having more motors to spread the heal throughout means more surface area on voice coils to dissipate this heat, meaning less impedance rise and greater efficiency of your watts. [/QUOTE]
