The Sonos Beam is a rectangular-shaped soundbar with rounded corners. It measures 651mm x 68.5mm x 100mm (W x H x D) and weighs 2.8kg. The enclosure is made from plastic and it features a fabric mesh -- it protects the speakers and wraps around the entire frame. Beam has four full-range elliptical woofers, a single tweeter to enhance dialogue, and three passive radiators. Furthermore, the device has five Class-D amplifiers and a microphone array with five far-field microphones. Overall, it's a compact and stylish design with just a little bit of branding.
