Osborn Epitome Tower
"Very few loudspeakers at any price can match the transparency, detail, dynamics, weight and sheer power of this combination".
The Osborn Epitome has been one of our biggest sellers for over 20m years, and has consistently outperformed speakers costing 20 times as much. Because of the extraordinary improvement in sound quality, when the optional Bass Units were added, around 75% of customers opted for them. The only people, who did not, did so for either financial, spousal, or space problems. Because of this, and because of the enthusiasm that has greeted the Eclipse Tower and the Pinnacle, we decided to finish of the Tower range by introducing the Epitome Tower. The Epitome Tower is pretty well a slightly scaled down Monument, to accommodate the 10" bass drivers, instead of the 13" drivers used in the Monument. This results in a slimmer and elegant piece of cabinetry, which is actually 2cm slimmer than the Epitome, whist retaining the same height as the Eclipse Tower. This gives it the performance of the Epitome and Bass Unit combination, whist only taking up the same floor space as the Epitome alone.
The Osborn Epitome is one of the finest speakers in the world, with unmatched speed and transient attack. But in the tower version the performance becomes extraordinary. The dynamics, bass, transparency and sheer power becomes unmatched by virtually any other speaker at any price. Very few other speakers 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, like this speaker can. Transparency, dynamic contrasts, and detail are transformed over the Epitome alone, and of course the bass becomes unsurpassed in speed, power, depth and detail. The sound stage is also greatly enhanced in both width and depth and in the 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 is hard wired with specially selected ultra wide bandwidth, ultra high speed data transfer cable and weighs about 9 kilograms.
best quality Turntable/CD Player and Amplifiers were used in the
design of these speakers. High quality timber veneers are used
on these speakers. Standard finishes are Jarrah and Bubinga. The
cabinets are shaped using high precision, computer controlled
milling equipment. All models are constructed from 32 mm Customwood
and are heavily braced. The Grand Epitome Tower is also fully
lined with a felt/lead/felt sandwich as used on the Grand Monument
Reference. Both models 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.
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: Dynamic range and speed unmatched by any speaker in any price range and the ability for drums to retain their impact and depth.

The Grand Epitome Tower Reference features heavy lead lining to all exterior surfaces. The same heavy bracing is used, but all areas between the bracing are covered by a unique sandwich lining. Heavy acoustic felt is used to separate the heavy lead sheet from the cabinetry. A further layer of heavy acoustic felt is placed over the lead and the entire sandwich is stapled to the walls of the cabinet. This result is what is effectively a box within a box. Wrapping the outside of the speaker is similar to knocking on a brick. This totally inert cabinet construction results in the ultimate sound reproduction.
