So much for so little…
It is time to raise your expectations. The Bowers & Wilkins 300 Series rewrites the rulebook on
to in terms of audio, and what many of us can afford. The 300 Series dramatically reduces the gap between aspiration and acquisition. Quality can no longer be measured in direct proportion to price. On features where rival ranges would make sacrifices, the 300 Series refuses to compromise. But how?
The simple fact is that the acoustic engineers at Bowers & Wilkins who brought groundbreaking technology to the acclaimed Nautilus™ 800 Series were not prepared to abandon all they had learned when they came to design more affordable ranges. They raised the stakes and you reap the benefit. Let’s take a closer look at the three models that make up the 300 Series.
Formerly available only in the more exclusive ranges,
the 300 Series incorporates for the first time in a speaker of its class the Nautilus™

The LCR3 is magnetically shielded so that it can be placed right next to a TV without distorting the picture. The symmetrical driver configuration gives a choice of orientation for a truly versatile home
theatre speaker; horizontally as centre channel on top
of the TV, or in vertical position to left and right.
There’s the DM303
the picture. Finally, the ASW300 subwoofer delivers an added kick to the bass output of your 300 Series system. Featuring a 200mm paper/Kevlar® cone, the ASW300 will sit discreetly in your room, its internal 100w amplifier generating a noticeably more powerful sound environment, whether
from a stereo or home theatre system.
The range features a host of
The bass/midrange drivers of the DM303 and LCR3 use woven glass fibre cones, which function in a similar fashion to the Kevlar® cones used in B&W’s more exclusive ranges by cancelling out unwanted sound waves. Distortion and signal degradation are minimised by an
All of these ingredients are skillfully blended to offer a level of performance unprecedented at this level, and
matched by a stunning design. The front baffle, moulded in inert
Versatile and affordable, beautifully designed and easily expandable, the 300 Series is the perfect introduction to the world of Bowers & Wilkins.
With a powerful bass frequency output generated from inside a compact and stylish cabinet, the ASW300 subwoofer is the ideal partner for any 300 Series home cinema or stereo system.
All three models incorporate Flowport. The dimpled surface of the flared ends of the tube use golf ball
aerodynamics to smooth the airflow through the port, reducing turbulence noise to negligible levels.
