Atesia SGS

Atesia represents the most important result of our design effort. It is a floorstanding loudspeaker equipped with all the most successful technical characteristics that continue to distinguish the products of Albedo brand as transmission line bass loading, ceramic membrane drivers, time-consistent crossover and, not least, the original design of the cabinet that stands in the best tradition of “made in Italy”. 190 cm tall and 215 kg heavy, this model stands at the top end of the high end loudspeaker market for domestic use and boasts the most sophisticated technical solutions. Four 190 mm aluminum/ceramic sandwich woofers drive two twin transmission lines equipped with decoupling chambers and filtering acoustic resonators, for an extremely sharp and articulated low range. Medium range is entrusted to two units with a pure ceramic membrane with anular magnet, while the high range is reproduced by a tweeter with a diamond inverted dome. Cabinet has a stiffening system consisting of metal side plates secured by steel bars. The whole rests on a solid aluminum base obtained from milled pieces.

The 25mm Tweeter with a hard Diamond inverted dome ensures greater off-axis dispersion along with an unmatchable details levels and very ultra low distortion.

The hardest material in the world at the complete service of high-end audio, only to achieve sonic perfection. It seems like a dream but our ATESIA SGS is likely to make it come true.


The precision and depth of the soundstage reach an incredible level of realism, where the dynamics and clarity of every sound detail of the original input signal are reproduced with incredible naturalness and smoothness. 


"Silver, Gold and Supreme"


"Atesia SGS" now flaunts a new reference audio level.


The crossover now takes advantage of the indisputable quality of the best Mundorf components, such as "Silver Gold Supreme" capacitors, "Supreme resistors" and "ZeroOhm" inductors.

Our aim was to maximize the quality of those components with a crucial role in passing the audio signal and that could otherwise limit the performance of our drivers.


And it is for the same reason that we then decided that it was also necessary to select a new interior wiring of superior quality.


That's why our "Atesia SGS" can now also benefit from the reliability of Van den Hul's silver-plated cables

215 kg by 190 cm tall of pure music


The mammoth size of our Atesia SGS is not a pure aesthetic whim, but also responds to specific mechanical inertia requirements for the cabinet. Our aim is to achieve maximum precision and efficiency, and therefore maximum sound realism.


The cabinet, in addition to using thick multilayer wood panels, also employs heavy steel plates to increase its stability and two other side plates that compress the cabinet to further increase its structural rigidity.


In this way we try to expolit all the acoustic energy that our transducers can reproduce without this energy being dispersed in vibrations or heat.


"Virtually indestructible sandwich Woofers"

Atesia "SGS" aims to reach all extremes of the sound range and to reach the deepest bass, it uses Woofers made with an exclusive almost indestructible aluminum sandiwch honeycomb membrane, capable of reproducing even seismic movements.

These exceptionally strong membranes feature the best combination of torsional and flexural stiffness which allows for a very low level of delay and energy storage. They are capable of reaching high levels of linear excursion (+/- 16mm) while maintaining a very low level of distortion.
