Give a larger living room or home cinema the scale it deserves. The 603 S3 is the flagship floorstanding model in the 600 Series, built to let a full orchestra breathe, give vocals natural presence and bring film soundtracks into the room with convincing weight.
Its Titanium Dome tweeter is partnered by a dedicated Continuum cone FST midrange, so voices and instruments remain open and precisely placed as the music becomes more complex. Twin paper bass cones and a Flowport cabinet supply the depth and momentum that distinguish this tower from the smaller models in the range.
This is a natural choice for listeners who want an involving stereo system without moving into Bowers & Wilkins' reference ranges, or for the front channels of an ambitious cinema. Improved terminals provide a cleaner signal path, while Black, Oak and White finishes make the pair easy to settle into the room.
