The sub is rated at 15 watts, while the satellites are rated at 4 watts each.
All enclosures are plastic and all controls and connectors are on the rear of the sub.
An AC output wall wart is used rather than a built in power supply. Using Milli Vanilli as my bass testing CD, I achieved a whopping 100-decibel peak output at a distance of two feet. Volume wise, this is only 10 dB less than the Altec Lansing ACS-48s reviewed recently. The MLi-460s do not fall into that category. Two knobs protrude from the sub enclosure.
