B&W 203i

Bowers & Wilkins serie200
Floor-standing loudspeaker system

Product Summary
The 200 series was deemed as the rarity in the mass consumer hi-fi market – a reasonably priced loudspeaker that provided high sensitivity, extended linear frequency response and pinpoint stereo imaging.
The 203i is a fourth order low-pass vented loudspeaker system. The speaker comprises of a 3/4-in high frequency with a polyamide dome and one 7in low frequency polypropylene cone.
The B&W wall bracket accessory permits easy, multi-directional positioning on walls.

Technical highlights
The Design incorporates a cabinet profile and wedge shaped grilles on acoustically transparent frames.
The magnetic fluid-cooled voice coils are a B&W hallmark, wound on glass reinforced Kapton® formers, enabling the drivers to take the heat when reproducing modern digital recordings.
In common with all B&W tweeters, the lightweight units incorporate low viscosity magnetic fluids to offer excellent power handling and linearity
