The Monoprice Harmony XL portable Bluetooth speaker is the perfect speaker for the home or on the go. Small enough to fit in a backpack or bag, the Monoprice Harmony XL features 30 watts of power delivered to two DSP tuned drivers, resulting in deep bass and clear, crisp highs. Utilize the True Wireless Stereo functionality by adding an additional Harmony XL and enjoy true stereo sound from a pair of portable Bluetooth speakers.
