Our Verdict

Marshall Acton III

JBL Authentics 200

Both the JBL Authentics 200 and Marshall Acton III draw inspiration from vintage guitar amplifier designs and are roughly the same size. However, the Marshall goes a step further with knob controls and switches with a more retro look. Both speakers need to be plugged in to work, but the JBL Authentics 200 works better for a home speaker since it has Wi-fi support and integration for Google and Amazon's voice assistants.
