Osborn Eclipse and Reference Eclipse
"Very few loudspeakers of this size at any price can match the transparency, detail, dynamics, weight and sheer power of the Eclipse".


               
The Osborn Eclipse has been designed and constructed in Australia, without compromise, in order to obtain the highest possible sound quality. The only criteria in the choice of components, materials, size and cost is the achievement of the ultimate sound quality in a speaker less physically imposing than the Osborn "Epitome". We believe that our design goals have been realized with this speaker.
The Osborn "Eclipse" is one of the finest speakers in the world, with unmatched speed and transient attack. It has been designed for the Asian Market and smaller European homes and for people who want most of the power and authority of the larger "Epitome" but can not accommodate their sheer size.
               The dynamics, bass, transparency and sheer power becomes unmatched by virtually any other speaker at any price. Few other speakers anywhere near their size can deliver the whole weight, power and authority of a full symphony orchestra. From the tinkle of the tiniest bell to the blast of a brass cannon, to the depth of a giant 32 foot pipe organ, with pin point imaging.
               Several of the world's best speakers were used as references in the design of these speakers. We believe that the sound quality of these speakers is superior to all the references. The drive units were chosen from the best available from around the world for unrivalled speed and accuracy. As a result, a level of transparency comparable to the best Electrostatic speakers has been achieved.
               The crossovers use the best components attainable. The capacitors are imported from America and the inductors are wound in-house as none are available commercially which meet our criteria. Each crossover weighs about 5 kg. each and is hard wired with specially selected ultra wide bandwidth, high speed data transfer cable.
             The cabinets are shaped using high precision, computer controlled milling equipment. All models are constructed from 32 mm Customwood and are heavily braced. They are exceptionally heavy, solid and are acoustically inert. The Reference Eclipse is lined with a felt/lead sheet/felt sandwich for unparalleled cabinet solidarity.  High quality natural timber veneers are used, and every cabinet is carefully hand finished to ensure a superb quality finish which will grace any living room.
              Only the best quality Turntable/CD Player and Amplifiers were used in the design of these speakers. These speakers have a number of outstanding features - the ability to separate instruments and place them firmly and accurately on a sound stage of uncanny width and depth. The instruments retain their correct pitch, tone and shimmer with a dynamic range and speed unmatched by any speaker this size, in any price range, with drums retaining all of their impact and depth.

Larger amplifiers can be used, but take care. If the speaker distorts, back off the volume. The above specifications show why these speakers are capable of such extraordinary transient performance and yet reveal such intimate detail in the music. This fidelity is possible due to the fine tolerances and light weight of the driver cone and voice coils.

The warranty on these speakers is five years parts and labour from the date of purchase.
