The Osborn Interlude has been designed and constructed in Australia, with no compromise in order to obtain the highest possible sound quality for a speaker of this size. We appreciate that our larger and more powerful models may not suite either spouses or decor, this speaker is an excellent compromise. The criteria in the choice of components, materials, size and cost is the achievement of a sound quality as close as possible to the larger Osborn "Epitome" and "Eclipse". We believe that our design goals have been realised with this speaker, now in its third generation.
          
          They were designed for the person who wants a big, powerful sound which is equally suited to the demands of Home Theater applications as well as being perfect for all types of music, from the most delicate to the most demanding. They are also excellent as rear speakers in a high quality Home Theater System where identical or larger speakers are used as the mains. These are the speakers chosen as rear speakers by the Sultan of Brunei where cost is not a consideration. If cost is a consideration, the F4 will deliver most of the strengths of this speaker, at a more affordable cost.

          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 any where near their price. Several type of cabinets were tried during the evolution of these speakers. They are constructed from 32 mm Customwood (1 ½"). High quality timber veneers are used on these speakers. The cabinets are shaped using high precision, computer controlled milling equipment. They are exceptionally heavy, solid and are acoustically inert. 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. The drive units were chosen from the best available from around the world for unrivaled speed and accuracy. As a result, a level of transparency comparable to far more expensive speakers has been achieved.

          The crossovers use the best components attainable. The capacitors are imported from the U.S.A. and the inductors are wound in-house as none are available commercially which meet our criteria. Each crossover is hard wired with Ultra Hi-Speed, Ultra wide bandwidth, Data Link Cable. The crossovers weigh approx. 6 Kg. each.

          It is this minimal compromise approach which results in stunning sound quality. Only the best quality Turntable/CD Player and Amplifiers were used in the design of these speakers. It is this attention to detail and no-compromise approach which allows these speakers to achieve their design goals. They are very easy to drive and do not present any difficult loads to amplifiers. "Super Amps" are not required. Modest power, high quality amplifiers are recommended. They perform exceptionally well with smaller valve and single ended amplifiers.

          These speakers have a number of outstanding features - The ability to separate instruments and place them firmly on a sound stage of exceptional width and depth: The instruments retain their correct pitch, tone and shimmer: Dynamic range and speed unmatched by speakers in their size and price range and the ability of drums to retain most of their impact and depth.

                 The Interlude is the perfect comprise between size and performance. It has the same sense of power and authority as the larger speakers in the range, and is capable of an amazing performance, in both music and in home theater applications. The 8" mid bass is the same driver used as a bass in the Eclipse. It is stunningly fast with a spectacular dynamic range, giving a performance which will satisfy anyone who wants a big sound, but does not have the space or decor to suite a larger speaker.

                  The above specifications show why these speakers are capable of  such extraordinary transient performance for such a relatively small  speaker and yet reveal such intimate detail in the music. This fidelity is possible due to the fine tolerances  and light weight of the driver voice coils.
                  This minimal compromise design allows the natural life and  excitement of  the original live performance to be faithfully reproduced. It is vitally important in the accurate reproduction of music, that there is no dynamic compression to strangle the music during transients.   The transient ability of  the Interludes and their ability to play accurately at whatever volume the music takes them, is unsurpassed.

The warranty on all Osborn Loudspeakers is five years parts and labour from the date of purchase.
