Eos

Martin DeWulf  from Bound For Sound (USA) commenting on the Eclipse Review, where they speculated on how the earlier model of the Eos would sound.


MGD comments: To address some of Dr. Weiner's speculations. 1 have heard in the Big Rig an Osborn speaker very similar to the one of wistfully dreamed of above.  It had the lead lined cabinet, but crossover work was still proceeding. Nonetheless, it may have been the finest sounding 2-way bookshelf speaker I have ever heard. The lead lined cabinet works, as does the marvelous tweeter. The speaker sounded much, much larger than it actually was.
It extended deeper in the bass in a manner that was amazingly tight and tuneful. The music in the mids was solid, musical discontinuities so accustomed to by the trained ear, were gone - and the music took on a presence that made me love the speaker. In many ways it sounded like a mini Silverline LaFolia and I can't give it much higher praise than that.

Eos: 

The Osborn Eos 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. 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", but in a bookshelf sized speaker. When the bass driver of the legendary Titan became unavailable, we needed to come up with a viable alternative, preferably in a smaller size, as the size and 26 kg weight of the Titan was a problem in some applications. To achieve the performance of the Titan in a smaller size was going to take an incredible mid/bass driver. We believe that our design goals have been realised with this speaker. The driver utilises the Utopia "W" Cone and a Neodymium magnet for towering performance. The soundstage size, dynamics and bass extension, is hard to believe from such a compact design. One of the first people to hear it summed it up when he said. "This might sound like a cliché, but the hair on the back of my neck is standing up." 
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 anywhere near their price. Several type of cabinets were tried during the evolution of these speakers. This is the best that we could achieve. They are constructed of 25 mm Customwood (1") 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 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, Cable. 

Eos Reference:

The Reference version uses the Osborn Reference lead lining where the inside of the speaker is lined in a heavy felt, heavy sheet lead, heavy felt sandwich virtually  eliminating cabinet vibrations and resonances.   It also utalises one of the finest tweeters in the world , usually found in speakers costing 10 times as much. and some superior components in the crossover for a quite surprising increase in the already exceptional performance performance.    

Eos Reference Elite:
 

The Reference Elite version uses the absolute best crossover components available and the only criteria in their selection is their towering performance and 90% of Eos sales have been Elite versions since their introduction as every listener is incredulous that something so good, could improve that much.
As of 012/07/2019 all Elite versions will be the Mk 11 version where the cabinet size has increased by 1.5cm to accommodate an all new mid bass which has increased in size from 6" to 7" and the price has increased just enough to cover the increased cost of this phenomenal driver, which once heard, could not be resisted.  The cone is a specially treated paper.  The driver uses a compact under-hung motor systems with large neodymium ring magnets. The patent pending motor offers a very long linear excursion together with a very high force factor. 
The back is shaped to duct the airflow around the motor and with the very open cast-aluminium chassis design the driver is virtually free from compression and any turbulence type distortions.  It is known as the "Best of the best" and it really is giving the speaker an even more impressive bass performance and an absolutely sublime vocal rendition.


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. They are designed to perform their best within about 20 to 30 cm from the back wall, so are perfect for bench or shelf placement. They also have such an incredible dispersion, that they do not need to be toed in. 

          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.



 

Tweeter (For Reference Eos)

29mm soft dome tweeter with a high efficiency ring magnet consisting of 6 radial neodymium magnets.

Tweeter (For Eos)

25mm fabric dome with an optimally shaped dome and a wide SONOMEX surround. Low viscosity magnetic fluid which provides excellent cooling while maintaining a low resonance frequency. 6 mm solid metal front plate with a slight loading characteristic which ensures linear frequency response, and a stiff and stable connection to the cabinet. A double magnet system, with a substantial injection-moulded rear chamber, with complex internal shape and reinforcing ribs, which eliminate unwanted chamber resonances and reflections.

Mid/Bass

165mm "W" Cone. 40mm voice coil with Neodymium magnet.

Eos Reference Elite Mid/Bass

The cone is a specially treated multi layer paper .  The 180mm driver uses a compact under-hung motor systems with large neodymium ring magnets. The patent pending motor offers a very long linear excursion together with a very high force factor.

I've owned the Eos Reference speakers for a year now and I am not the only person who's enjoyed the sound. I can be in another room and can clearly hear the musicians in the sound stage. I highly recommend these speakers. I have had them in my living room and not only do they look stylish, but the build quality, the Tasmanian Blackwood gloss finish, and the sound is truly reference quality. Everything that has been said about the Eos is true.  A nice big transparent sound, but not too big.
I wanted to go for a smaller speaker for convenience and to be more neighbourly friendly, which is working.  Throughout the house their sound is great, some speakers can't do this off centre. All of my CD and record collection sound good on them. 

My previous speakers, the Osborn Epitome were excellent, and just got better with every change I made. I expect the Eos to do the same, as I am currently upgrading my system, with a new integrated and adding a Osborn T12 subwoofer, just cause I can. I am looking forward to hearing the two together.
