Common questions
The main difference is the size of the speakers and, as a result, the driver and amp configurations that affect the sonic quality and audio experience. Therefore, each speaker is suitable for different-sized rooms and varying loudness. Most of the connectivity and controls are the same across the Home Line III models, except for Acton and Woburn. Acton doesn't have RCA input, and Woburn is the only model equipped with an HDMI connector, making it more convenient to use with a TV.
