CYRUS ONE linear Bookshelf speakers 20W-120W (Pair – White)

The Cyrus ONElinear is a premium loudspeaker system, which, whilst designed to perfectly augment the Cyrus ONE and ONE HD amplifier systems, provides exemplary performance with a whole host of audio systems.

The ONElinear is engineered with a classically ‘British’ linear frequency response curve. The objective is complete neutrality, allowing the full character of the music to be revealed. A loudspeaker, however, can only be truly perfected if it is known which amplifier system will be driving it. In this case, the ONElinear has been optimised for use with our own hybrid Class D amplifier topologies.

The ONElinear bass/mid driver uses a double-wound copper-coated aluminium voice-coil. As well as being light, this produces a stronger induced magnetic field and hence ‘grip’ over hard to control bass frequencies. The voice coil is bonded to a carefully profiled KEVLAR cone material. This material is light and responsive, carrying limited inertia and retaining its shape and hence audio characteristic even when pushed hard. The speed and accuracy of the resulting bass response is remarkable for a speaker of the size.

The ‘tweeter’ or treble unit is a textile soft-dome, capable of meaningful response well beyond the limits of human hearing. Refined and balanced, the high-frequencies are never ‘aggressive’ or harsh, yet retain the full detail of the source recording.

The crossover uses high quality electrolytic capacitors to maintain the signal integrity and a smooth phase response through the transition from bass driver to tweeter. This again contributes the even response.

The cabinet has been developed using advanced computer modelling with ‘Delayed Cumulative Spectral Analysis’ to reduce the contribution of cabinet noise to levels more than 35dB below the driver output. The same computer modelling is also used to fine tune the crossover to ensure a consistent performance, even when listening ‘off-axis’.

The ONElinear is rear-ported and designed to be positioned between 10-30cm from a rear wall. This will optimise the bass response and mid-range clarity, although some experimentation with position is advised as this will be room-dependent.

Itʼs widely understood that the sound of surround TVs cannot compete with the excitement of a properly designed and equalised home theatre system. But great sound comes at the expense of living space…until now. The wall-hugging RX-FX surround speaker reconciles the problem by providing a convincing, enveloping timbre-consistent surround sound that places you on the edge of your seat and at the heart of the action. Discreet enough to be flush-mounted on side or rear walls, the RX-FX design will blend with the system and your décor so completely youʼll wonder why you ever thought of compromise. Itʼs also immensely flexible sonically, offering direct or diffuse sound effects at the flick of a switch.

The M-1 has been engineered with the same design attributes and ethos as B&Wʼs larger ranges. Perhaps the most striking thing about the M-1 is the weight and strength of its curved aluminium cabinet. This is combined with a strong, glass-loaded ABS front baffle. Together they provide an excellent cabinet: the curved aluminium is stiff and the ABS offers excellent and appropriate damping characteristics.

The M-1ʼs drive units were developed by Bowers & Wilkins specifically for the design. The metal dome tweeter benefits from refinements developed for the new B&W 800 Series and includes Nautilus™ tube loading and neodymium magnets. The glass fibre bass/midrange coneʼs ability to absorb standing waves has been further enhanced by the inclusion of five strategically placed resin filled slots that further minimise distortion.

The result of this detailed cabinet and drive unit engineering has allowed B&Wʼs engineers to borrow another feature from the new 800 Series and utilise the simplest of electronic equalisation in the M-1ʼs crossover. Each of the drive units is fed by only a single, carefully selected component. This approach to crossover design, although painstaking as it relies on optimising all of the physical components in a design, is crucial in achieving its aim of neither adding to nor subtracting from the original signal.

The M-1 is available in three colour options - black, white and silver, each with chromium plated stem and table base.
