Bowers & Wilkins M1 Surround Speaker



Forming the basis of a completely revised Mini Theatre concept, the new M-1 combines a cleaner aesthetic with dramatically improved performance. Combine it with either the ASW608 or the new PV1D subwoofer to create a home theatre experience with superb integration and impressive power for such a discreet system. Plus, its more extended bass response allows M-1 to be used on its own for two-channel applications. Mount the speaker as shown on a table or shelf. Alternatively, a bracket is included for wall mounting and a floor stand is available as an optional extra.
