With over 40 years of playback and 25 years of concert recording experience, Kostas Metaxas has never been known for being understated in his designs.

Once Metaxas perfected the art of CNC machining organic shapes with amplifiers, it opened up similar possibilities with speakers. CNC allows the sculpting of a shape with incredible rigidity, in a much smaller form factor than is possible with other materials. At the same time it minimises front baffle diffraction whilst maximising internal volume.

Kostas told us: “With more than a passing reference to Homer’s Odyssey, the apt metaphor is testimony to the sheer musicality and realism that allows this potent 3-way system, CNC carved from a block of solid aluminium [or titanium] to engage and captivate it’s audience with its sound and to invigorate the mind with it’s extreme sculptural aesthetic.

At home in the most demanding recording studios, concert hall monitoring booths or even the Museum of Modern Art, the Sirens are a radical departure from the original concept of a 3-way box speaker developed early last century”.

Using ideas borrowed from Neumann TLM 50 and M150 microphones, the Siren embeds the Accuton drivers into spheres mounted onto an organic “time-aligned” sculpture. Despite the unique and unusual shape, the design is a seriously engineered, no-compromise loudspeaker with emphasis on absolute sound quality. Accuton ultra-low colouration ceramic drivers are used in some of the most expensive systems currently available, but it’s only when you marry them to a curvaceous, stiff, inert massive machined “body” that you can really hear – and probably for the first time appreciate, their sheer neutrality and incredible 3-dimensional spatial rendition of a concert performance”.

The final version of the Siren is CNC machined in 14 pieces [pair]…almost 6 weeks of 24-hours-day per speaker of the most intricate, “organic” machining EVER done for a speaker – or for that matter, any piece of hi fi equipment. This is really “Art in the service of Music””

In a “bespoke” manner, the actual configuration of drivers can be chosen, Since there are different “levels” of Accuton ceramic drivers, up to and including their ultra-expensive “diamond” tweeter, the customer has a choice of which tweeter, midrange and 8″ woofer they would prefer to use now, or in the future.
