B&O Tech: The Naked Truth III #18 in a series of articles about the technology behind Bang & Olufsen loudspeakers Another busy week – so another set of photos… BeoLab 2, showing the driver with two spiders to make sure it doesn’t rock (or wobble) when it’s really moving… BeoLab 19 BeoLab 19 closeup, showing the ribs in the casing to improve its stiffness. BeoLab 14 satellite. Note the thermally conductive grease that is put between the back of the driver magnet and the outside enclosure to help radiate more heat out of the loudspeaker and keep it cool. BeoLab 18 with an early prototype plastic grille. BeoLab 18 without the grille. BeoLab 18 side view. BeoLab 18 showing the internal circuit boards (power supply, DSP board and amplifiers). The grey bits are an acoustically absorptive foam that helps to attenuate standing waves inside the enclosure. These are rather strategically placed in order to have the most effect. BeoLab 18 internal closeup. The entrance to the port is just below the lower woofer, on the other side of the grey foam.
