Fascination, which proceeds from this loudspeaker, become experienced, already with the first clocks. They will notice that the contraction AHT (Acoustic Hologram Technology) is not empty word case or Werbegag. We developed two years long the AHT and show in that Europe them their clear advantages in relation to conventional constructions.AHTist technically seen a special arrangement of Mitteltönern (two in front, one on the side), which is so wired that all three master the difficult task to already replace with very deep frequencies the bass but in the central clay/tone range only the highest of the three is responsible for the radiated sound. From this the advantages of a large diaphragm surface result to one with deep frequencies, with those alone. would be overloaded, and a small acoustic center with high frequencies, which the spatial illustration clearly improved and which increases locatableness strongly. In music seen AHTeine means extremely plastic, spatially seizable rendition, which shows all details of a music happening. Not only classical period or the jazz fans of it to be inspired to have, no also with Popmusik keeps striking one a realistic music reproduction. Supported by a fundamental, bone-dry bass and finest heights you will find out very fast the Lockerheit and Kraft that Europe and will again discover your disk collection!

By new meanwhile technology with extremely steilflankigen frequency switch filters, tested world-wide, succeeds taking the lower woofer with the Corvara for the first time so abruptly from the sound happening that he is to be already heard more with 400 cycles per second hardly and with 80 cycles per second the full reinforcement of a second bass chassis offers nevertheless!Thus we carry out for the first time the idea, which is behind an optimal 2-Wege-System: large diaphragm surface in the bass, small acoustic center with middle and higher frequencies. This technology of the steilflankigen filters continues to continue with the Corvara naturally also within the medium high clay/tone range. The Corvara possesses thereby a Aufwändigkeit in the frequency switch, which lets many 3-Wege-Boxen before envy plae. Thus a loudspeaker system develops for highest requirements becomes fair, because also the Corvara has that, for which our loudspeakers are world-famous meanwhile: perfect detaching the music of the loudspeaker. Already the outside form makes the Corvara something special one. The curved housing offers a substantially higher rigidity than a straight plate. In order to reach the curvature, three layers under pressure and heat will bake with one another. When internal layer is used flexible bending plywood, which offers good sound absorption and rigidity with small weight. Whereupon a slit MDFPlatte sits, into whose slots after the manufacturing of the housing wall sand is filled. Outside the Resopalträger with pressed on aluminum reinforces the wall additionally. The filling with fine-grained quartz sand brings mass and absorption into the housing wall and absorbs casing oscillations on a measure never known. Thus an extremely rigid, light loudspeaker housing high-absorbing however at the same time develops. The special to the Corvara however is the new technology, with which we the 2 - way technology redefine. With 2 - way system work both Tieftöner in the bass parallel, for middle frequencies the lower is slowly taken out, so that the acoustic center within the operational readiness level range becomes not too large, which well-known-measured to a laminar, discoloured Klangbild leads. By our new, into the Cortina is used naturally also our fine-drawing, neutral CLEAR wading he cable and provides thereby for a outstanding connection to your amplifier. Quartz sand filling MDF slit flexible plywood plate.
Elegant, timeless form. High-rigid, well dampened housing. Consistent adjustment on perfect acoustics. These opposite criteria we united all in the Cortina. The housing consists of several different high-absorbing wood beams and an upper aluminum layer. The walls are filled with 5 kg fine quartz sand, which provides for a outstanding absorption. By the curved form of the surface this multi-layer housing becomes extremely rigid - must in the building of loudspeakers. The noble, grooved aluminum surface can be supplied in any RAL-Farbe, without surcharge.The Cortina a three-way loudspeaker box with new, extremely steilflankigen filters on the 3 frequency switches is acoustically seen, for which we selected naturally only the best individual components. These frequency switch filters have the advantage that them a high maximum stress with at the same time low rattle/clink and to small stroke offer. By the rigid coupling the Cortina sounds to the phase position of these filters as from a casting, so as if only one loudspeaker chassis would be present. By our used sophistiated high-pass filtering the Cortina masters also high levels with deep basses spielerisch and has therefore in the normal music enterprise enormous reserves. Also in the Cortina are used only loudspeaker chassis, which we ourselves finished and which are therefore perfectly bred on their employment - Isophon-typically evenly. The fascinating to the Cortina is their clear transparent rendition, a detail and a play joy and a spatial Tiefenstaffelung - something which otherwise only many larger loudspeakers offer can.
What happens when you take the best loudspeaker drivers available on the world market and connect them with the most innovative and sophisticated frequency crossover technology regardless of costs and used parts?The isophon Cassiano offers you the answer.San Cassiano, a ski resort in Southern Tyrol donated the name for a unique loudspeaker project. The aim was to create a reference loudspeaker with almost compact dimensions which can be integrated into any modern living-room. In addtion, the music shall vanish away from the cabinets producing a sound stage as natural as can be.It took us at isophon many listening sessions disregarding price and effort of any component until the basic concept was clear.Since more than 20 years now the company of Thiel in Germany is dedicated to the design and manufacturing of ceramic diaphragms for loudspeakers. These diaphragms are thin and fragile but unite contradictionary properties like light weight, hardness and stiffness which are important for good diaphragms. The high speed of sound of ceramics shifts partial waves and resonances into the inaudible region where they can be cut off by steep frequency crossovers. These diaphragms enabled us to use our unique frequency crossover technology.
The first loudspeaker to be matched to your roomThere is always the prejudice that big reference-speakers need a big room to show their strengths. As normal livingrooms differ a lot from acoustically optimized studios we integrated a sophisticated room equalization system into the Arabba.Many living-rooms sound bright with long reverberation. Put the equalization bridge into the “Low“-position to take away the sharpness. An overdamped room always sounds boring. Here the “High“-position is of course benefitial. Start in the “Linear“-position to get a good feeling for the acoustical properties of your room.The bass response, too, can be adapted to your room. Small rooms prefer the “Low“- position while large rooms need the “High“-position. Of course you can use the „Low“-position in small rooms if you like a big bass or if you want to compensate the ear’s low sensitivity for deep frequencies when played in low loudness.Why a frequency crossover?Like practically all renowned reference loudspeakers in the world the Arabba is a three-way loudspeaker. This means that the frequency range between 20 Hz and 20,000 Hz is divided into three sections: the bass, midrange and highs which are irradiated by different drivers. This is recommendable because woofers have to be big and heavy and tweeters small and light.
