This is the bluetooth speaker with built-in Alexa from the iconic amplifier brand Marshall that delivers superior sound. It bears an iconic Marshall exterior design: textured vinyl covering, script logo in the middle of its salt and pepper fret, and sturdy wooden enclosure. A brass plate with five blue LEDs signifies that Alexa awaits your command for modern application while the subtly etched 1962 establishment date reminds an owner that the speaker’s inner workings remain faithful to the quality sound production for which Marshall is known. The speaker’s three class D amplifiers deliver well-balanced, powerful sound up to 30' away from twin 15-watt tweeters and one 30-watt bass-reflex subwoofer when connected wirelessly to any Bluetooth 5-compatible smartphone, tablet, or computer. You can adjust volume, bass, treble, and select from built-in EQ presets using the speaker’s top-mounted knobs and plug in a set of headphones to its built-in 3.5mm input. Even when the music is playing at volume, its far-field microphone array’s voice recognition and noise cancellation ensures requests for Alexa to play your favorite playlist, help with identifying lyrics, or assist you learning a new chord progression on your guitar will be heard. It can also switch between two Bluetooth 5 devices to play from different playlists. Alexa functionality requires connection to an existing home WiFi network. AC plug. 6 1/2" H x 10 1/2" W x 6" D. (4 1/2 lbs.)
