Featuring twin 200mm bass drivers and an 85mm BMR in a 60 Litre enclosure, the Ovator S-600 is designed for larger listening rooms and for use with upper echelon Naim amplification. With bass extension down to 28Hz and maximum levels that can do full justice to the dynamic range of live music up close, the Ovator S-600 offers the ultimate in wide bandwidth and dynamic music making.

Hardened floor spikes

Surgical grade, anti-magnetic, stainless steel M8 floor spikes define the vital mechanical connection between the speaker and the floor of the listening environment.

FEA modelled driver chassis

Ovator bass drivers feature rigid paper cones, natural rubber surrounds and aluminium demodulations rings within their neodymium magnet systems. The S-600 bass drivers additionally incorporate generous pole-piece ventilation. The linearity and resistance to compression of both Ovator models' bass drivers is outstanding.

Computer-modelled crossover

The crossover incorporates state of the art components including laminated and air-cored inductors, and metallised polypropylene capacitors.

Decoupling leaf spring

A steel leaf-spring provides the connection between the enclosure and plinth and decouples above 12Hz.

Die-cast plinth

The pressure die-cast plinth incorporates enclosure locations, housing for the crossover, and floor spike fittings with top-access adjustment.

Rigid multi-composite enclosure

The enclosure is constructed from a combination of 25mm and 50mm panels comprehensively braced to provide a rigid, non-resonant and low diffraction reference plane for the drivers. Selected panels also benefit from strategic mass-damping, and the internal bracing includes a division that creates separate loading volumes for each bass driver.

Computer-optimised bass driver

The Ovator S-600 bass driver features a rigid paper cone and natural rubber surround together with aluminium demodulation rings within the magnet system and generous pole-piece ventilation. Its linearity and resistance to compression is outstanding.

BMR Isolating Enclosure

The BMR is mounted in a 12.7mm wall thickness extruded aluminium cylinder nested within the main enclosure. The cylinder, extending the full depth of the enclosure, is gradient-filled with damping materials selected through technical analysis and critical listening.

BMR driver

The BMR driver comprises a honeycomb diaphragm driven by a voice-coil immersed in a twin-neodymium magnet system optimised for linearity through finite-element analysis. The pressure die-cast chassis provides the rigidity necessary to ensure that every last note of musical detail is accurately reproduced.

BMR Suspension

The module comprising the BMR and its enclosure is suspended within the main enclosure by twin circular duralumin plate leaf-springs - one at the front of the enclosure and one at the rear. The resulting suspension system decouples above 4Hz - more than six octaves below the BMR pass-band.

The Ovator S-600's balanced mode radiator (BMR) constitutes its most visible technological advance, yet the performance of this loudspeaker is equally the result of painstaking refinement in numerous elements of design, construction, and material selection.

For example, there is so much more to the musical reproduction of bass than low frequency extension, so the Ovator S-600 LF driver is designed not simply to play bass, but to do so with faultless musical accuracy. It incorporates a multitude of electro-acoustic details aimed at minimising distortion and compression, and the result is extended bass with peerless timing, dynamics, and pitch accuracy. One vital element in the design of a high performance bass driver is its chassis. Great rigidity and an open structure are vital but potentially conflicting requirements, so the pressure die-cast bass driver chassis of the Ovator S-600 incorporates a triangulated framework, borne of finite-element analysis, that ensures both rigidity and unimpeded air passage.

The Ovator S-600 crossover network is housed within the plinth and divides the audio signal between bass drivers and BMR with fourth order acoustic slopes at 380Hz. Each component selection is the result of intense technical analysis and listening, and the component arrangement is fundamentally informed by the layout and earthing techniques developed for Naim power amplifiers. A crossover module suspension system and individual component decoupling ensures any chance of microphony is minimised. Conversion to either bi-amp or tri-amp active drive is easily achieved through removal of the crossover module.

Just as much as it is BMR technology, it is the fine detail and the sum of the parts - the result of decades of speaker experience and development - that makes the Ovator S-600 so remarkable.

Balanced Mode Radiator Explained

The Ovator S-600 Balanced Mode Radiator (BMR) is the result of intense effort in both development and manufacture. Not only does the design of such a driver demand great intellectual understanding, but consistent manufacture requires extraordinarily fine specification and control of the physical characteristics of its components.

The underlying concept of the BMR is to engineer a practical implementation of the theoretically wide bandwidth and linear acoustic output of an unconstrained vibrating diaphragm. In practice, this is achieved by attaching balancing masses to a constrained diaphragm in carefully calculated locations. Such 'mode balancing' modifies the diaphragm's vibrational behaviour so that it simultaneously operates in pistonic and vibrational modes to generate wide-bandwidth acoustic output with a flat frequency response, consistent dispersion and low distortion. Thanks both to the BMR's exceptional inherent performance and to the absence of any mid/high frequency crossover discontinuity, it takes just a moment's listening to appreciate the Ovator S-600's breakthrough levels of musical coherence, timing and clarity.

REVIEWS

Here is a selection of reviews that have been written about this product. Where PDF downloads or online links are available to us, they are featured.

  • Tone Magazine - November 2009

    "The Ovator S-600s are a tour de force of speaker design."
  • Hi-Fi World - August 2009

    "The Ovator is a step forward, moving away from the idea of cones acting as rigid pistons to move air, which cannot be made to work in practise"
