The Bowers & Wilkins CCM683 are a pair of in-ceiling speakers for your integrated home audio requirements. These are the 8-inch versions of the CCM663 speaker pair. Sitting just below the CCM682s they provide virtually the same level of quality & fidelity as the CCM682s. The main difference is simply the lower amplifier power these speakers have. If you dont require the full 150W of power then these speakers are most likely the best option for you. They still feature the same pivotable tweeter & EQ switch for the bass-mids as many of the other speakers in this range.
