Features:  LESS DISTORTION, MORE SENSATION:  R1600T III’s professional amplifier system is equipped with Digital Signal Processing and Dynamic Range Control to prevent audio distortion, even at the highest volumes. So you can crank up the music while still enjoying crisp, clean sound.   INSPIRED DESIGN, SOLID ENGINEERING UNITED:  R1600T III produces 60 watts RMS from the 4-inch bass driver and 19 mm tweeter drivers in each speaker.
