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. 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 gradientfilled with damping materials selected through technical analysis and critical listening. The bass driver chassis incorporates features on its mating surface that consistently define its interface with the cabinet and help manage vibrational energy. 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 Ovator S-600's pressure die-cast bass driver chassis incorporates a triangulated framework, borne of finite-element analysis, that ensures both rigidity and unimpeded air passage. fea Modelled dRiveR chassis BMR isolating enclosuRe The crossover incorporates state of the art components including laminated and air-cored inductors, and metallised polypropylene capacitors. 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. [. . . ] The resulting suspension system decouples above 4Hz ­ more than six octaves below the BMR pass-band. 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.
