Don't let its traditional appearance fool you. The Marshall Acton Bluetooth speaker is as modern as can be. A class D amplifier operates two tweeters and a woofer, making your music sound detailed and powerful. Everything about the Acton Bluetooth speaker refers to the successful Marshall guitar amplifier from the '80s. The vinyl cover, vintage grille, and the iconic Marshall logo take you to the time of rock & roll. Analog dials for the volume, the bass, and treble complete the vintage look.
