The New Athenaum Speaker System was developed by popular demand for a smaller version than the Acropolis, that would fit in many more living rooms than the Acropolis System. The horizontal dimensions are exactly the same as the Acropolis, but the height is about ½ that of the Acropolis.
We have striven to duplicate as closely as possible the exceptionally high performance characteristics to be found in the Acropolis system, and have, we believe, succeeded in this endeavor, while achieving a size and weight approximately ½ that of the Acropolis. The drivers used are exactly the same types as in the Acropolis, using the same Linn Audio proprietary compression driver/horn assembly, and the same woofer, albeit only one instead of the two used in the Acropolis. Also the ribbon tweeters have been eliminated in the Athenaeum, which instead achieves an extended high frequency response through a special mid range compression driver, which is good all the way to 20khz.
The same clear, transparent, and almost distortion free sound is available in the Athenaeum, while no serious compromises have been made to the quality of the sound by the reduction in the size of the cabinet, or elimination of some of the drivers.
The main compromise with the smaller cabinet is that the bass is not so far extended into the low end of the audio spectrum (30hz, instead of 20hz on the Acropolis.) However, Linn Audio sells a good low-frequency enhancement unit that may be employed with the Athenaeum system which, when properly adjusted, will create a completely flat frequency response down to below 20hz.
Also, the super-high end of the Acropolis system (40khz) may be reproduced in the Athenaeum by the addition of an optional pair of ribbon tweeters. (The same type used on the Acropolis) Both these performance-enhancing options may be obtained from Linn Audio at modest cost.
Note that in the detailed description links above, the Acropolis system is described, but almost all the discussed parameters apply to the Athenaeum system as well, save for the exceptions stated above.
The Athenaeum system is a tremendously good value, given the sound performance that is equal to or, in most cases, superior to any other speaker system on the market, regardless of price. And it sells for little more than half the price of the Acropolis system.
It is made of all wood, both solid parts and veneers, with no black painted parts, as with the Acropolis. It is available in a variety of wood types and finishes; shown in the image is a light cherry version of the system. It is a beautiful piece of furniture that will satisfy the most discerning home decorator, as well as all serious audiophiles.
The Delphi Speaker System, like our other two systems described above, is the culmination of decades of research and development, as well as countless hours of expert and critical listening. It is so clear and distortion free that it has never even been heard before. It gives the biggest, yet cleanest sound you will ever hear. It’s very high efficiency will perform well with tube amplifiers, even very low power ones, such as single-ended triodes, for the cleanest possible sound.
The Delphi system is based on a classic design from the 60’s and 70’s, with a cabinet that is reminiscent of some JBL offerings. It is also, like the JBL, a 2 way system, using a large paper cone woofer, combined with a compression driver/horn for the mid and high ranges, and installed in a front ported type cabinet.
JBL was the highest of the high end of its day, and we have started with the design principles of this classic model. However, we have dramatically improved the performance of the drivers, so that this Delphi system is far superior to any speaker product available at that time, or even to the present day, excepting only our other speaker models, above.
The Delphi is a 2 way system, that covers the entire audio spectrum, except for the very low end, and this low end may also be achieved using Linn Audio’s own sub-woofer system, for a small additional cost.
The unique aspect of this system (and all Linn Audio Loudspeakers) is the use of a compression driver horn for the mid-range and highs. Compression-driver/horns are basically superior to any cone type midrange, in that they have very low distortion (typically 90% less than cone drivers) as well as superior transient response and clarity. We have found that they also offer the best in reproducing the detail, imaging and sound stage of the original recording, not to mention very high SPL levels for a given power.
Horns are not typically used anymore in high-performance speakers, since they can have problems, primarily with resonances in the horn itself. This resonance can sound like distortion, though technically it is something different, so most high-performance speakers produced today use cone mid-range drivers. But Linn Audio, after years of testing and experimentation, has managed to eliminate the resonance problems with their horns, and therefore is left with all the inherent advantages of a horn driver, without the disadvantages.
The Delphi is a superior performing speaker, but at a cost that is less than our other two offerings. You get the exceedingly good performance, typical with our other two, but at a lower price, and smaller cabinet size and weight.
