High Performance Satellite (each) The ultimate style speaker, combining the best of Monitor Audio technology in a stylish, compact and rigid die-cast alloy cabinet. As capable with music as it is with home theatre sound, the beautiful Monitor Audio A10 punches like a heavyweight, expertly blending sky-wide high frequencies with a natural blast of mid-range detail coupled to a depth of bass that simply defies the A10's svelte dimensions. Its rigid die-cast alloy cabinet, piano-lacquered to a polished perfection imparts a sense of superior quality, and when teamed with a matching A40 at the centre and the awesome AW-12, the A10 completes a surround sound system unrivalled in its ability to combine the essential force of music and film sound and the power of de-rigueur design in a single fabulous statement.
