Furniture Design Waste Parts Loud Speaker by Pang Ming Waste Parts is a passive loudspeaker made from reused automobile components. The main body is the cylinder section of a discarded engine, cleaned and polished aluminium. The base is stainless steel, shaped by laser cutting and welding. The panel and assembly parts are aluminium and plastic. The dense, thick engine shell reduces acoustic resonance and noise from shell vibration. Waste Parts measures 440 mm in width, 330 mm in depth and 1200 mm in height. The loudspeaker is used with high fidelity playback equipment. The design gives car parts new value instead of simple recycling.
