With the advent of SuperSpeed USB 3 ports on modern PC's and Mac computers,
USB 3.0 speakers can potentially deliver even higher wattage output. Thanks to the maximum
 900 milliamps of power a USB3.X port can provide, we're seeing the first USB3 audio
systems that can deliver around four and a half watts of speaker power: 5 volts x 900 mA = 4.5 Watts.
That extra current will also allow computer speaker manufacturers to use slighty larger driver cones
with larger magnets that can deliver significantly improved bass response.

Can use old powered speaker set as donor.
The MA170 can be used as proof of concept.
