Cyrus ONE Linear Bookshelf Speakers
The Cyrus Audio ONE linear bookshelf speaker is a premium loudspeaker system, designed to perfectly augment the ONE series amplifier systems but provides exemplary performance with a whole host of audio systems.
The ONE linear 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 ONE linear has been optimized for use with our own hybrid Class D amplifier topologies.
The ONE linear 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 ONE linear is rear-ported and designed to be positioned between 10-30cm from a rear wall. This will optimize the bass response and mid-range clarity, although some experimentation with position is advised as this will be room-dependent.
