H.E.O.LO.H.E.O.LO. H.E.O.LO. is an innovative loudspeaker, developed to overcome

the typical limits of traditional acoustic transduction devices.

The H.E.O.LO. concept is based on the ability to completely dissimulate the presence of the loudspeakers themselves , so that the sound are not perceived as coming from them but from from the place in the space where each instrument or performer was

originally placed, regardless the listening position. The result is an acoustical scene that tightly approximate the musical event as it

was permormed during the recording session and that can be appreciated everywhere in your listening room.

We have spent months in studying and tuning all the components to find the right solution that fulfills all our strict sound

requirements. The result is the H.E.O.LO: concept that is the foundation of all our loudspeakers and that makes our systems

unique and inimitable.

Frequency response is seriously affected by the

listening position

High frequencies are very well perceived in front of a standard

loudspeaker.. But their level

progressively diminishes as you move aside

….. And they are pratically canceled if you move out

of axis

From the Craftman handsFrom the Craftman hands

An essential characteristic of all our products is that they are completely handcrafted. The

chassis, the crossover, the cabling, the assembling, the finishing are all made by

specialized craftsmen.

Small finishing differences and imperfections are not due to poor quality: they give you the

evidence that every single piece is handmade, not a mass production result.

From the Craftman handsFrom the Craftman hands

During the manufacture of the H.E.O.LO., the human intervention makes it possible that every relevant aspect of the construction process is verified step-by-step and every

single part is refined, leading to a reliable and absolutely constant result.

On each single H.E.O.LO., for instance, the drivers are pre-selected and the inevitable differences

are completely compensated with slight modifications on the crossover network.

Individual testingAn individual listening session is part of the production process of each single H.E.O.LO.. Each loudspeaker, after a technical test, is passed through a listening test, using a selected program including several musical genres using a standard setup. This phase is the one that over any other make it sure that the final result will always match the customer expectations.

…… the scene widens and gains that 3-d component that a lot of loudspeaker manufacturers chased ineffectively for a long

time….

Audiophile clubs..Audiophile clubs..

… ci sono le H.E.O.L.O., dei diffusori da pavimento di 88,5db di sensibilita’ che oserei

definire….camaleontici! Mai ascoltato un diffusore cosi’ semplice da pilotare e che si

trova a suo agio con tutto….persino con soli 3 watt in un ambiente molto trattato

acusticamente e di 25mq!!!Ho passato 2 settimane in compagnia di

questo splendido gioiello sonoro, non lo avrei nemmeno voluto restituire tanto mi era

piaciuto, tanto mi aveva rapito la sua estrema musicalita’.

…..Una nota di merito va fatta anche ad un assetto che sto ascoltando questi giorni, un diffusore prototipo (Heolo) dalle caratteristiche sonore

marcate con una predilezione per la ricostruzione spaziale davvero incredibile. Ogni strumento e’ minuziosamente riprodotto e collocato nel suo spazio ben definito, mai vicino al diffusore! Una

piccola torre che sparisce come un minidiffusore e sa fare di meglio nella ricostruzione spaziale, con

tutti i pregi di un estremo inferiore che non fa rimpiangere sistemi ben piu’ grandi.

……soundstage and clarity are just astonishing, Heolo are able to transmit

emotion almost like no others……
