ONElinear

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.

Design Principles

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.

Reviews

The ONElinear performs very well. I have high standards and having listened to hundreds if not thousands of speakers over the last 45 years I can soon tell if I like a speaker design or not. The ONElinear doesn’t disappoint. – Hi-Fi Pig
