Loudspeaker technology taken to the extreme
When developers are allowed to make the most of technology, when material costs only play a minor role and product designers have creative freedom, that is when ‘high end’ is created in its purest form. La Diva, our new top model, fulfills all of these requirements and is extremely ‘personable’ in spite of its name.
High and mid tone par excellence
The be-all and end-all of excellent sound are first-rate selected components - and the La Diva has these in abundance. Used in the treble range is a second-generation Fluktus tweeter. The 30 m polyfibre compound dome sits in a solid aluminium front panel with special wave geometry to ensure that the tweeter displays perfect dispersion characteristics. A powerful double-magnet system guarantees pure unadulterated performance up to the highest levels.
The elaborately designed midrange driver is powered by an AlNiCo magnet system. The combination of aluminum, nickel and cobalt, from which it gets its name, offers extremely high magnetic field strengths and is extremely temperature-stable, which makes our midrange driver unsurpassed in terms of dynamics and resolution. The 25 mm voice coil provides the thrust for the hard-packed membrane made from HECO’s legendary kraft paper. This is produced from pre-selected Nordic softwoods with particularly strong fibres, making it vastly superior to conventional paper membranes by virtue of the strong fibers, together with wool threads produced in Germany, forming a tightly bonded fibre braid that combines maximum stability with minimal weight. The separate midrange housing is open at the rear and aperiodically damped.
Bass to the power of six
It goes without saying that the bass diaphragms of the Heco La Diva are also made of kraft paper, with 2 x 200 mm specimens featuring 32 mm voice coils operating synchronously in the baffle. But there´s more: Four bass radiators, two each on the right and left, provide for even deeper bass down to 17 Hz.
The connection terminals, which not only offer the option of tri-wiring and tri-amping separately for each frequency range, but also facilitate direct adjustment of the high-frequency range by +2 dB and the mid-tone range by -2 dB, demonstrate that the technical care and diligence does not end with the details. It goes without saying that behind all this there is an elaborate crossover with components displaying the ultra-tight tolerances.
All of this is packed in an enclosure that is second to none. Solid and with a streamlined cross-section, it actually nips resonances in the bud inside. With its exquisite and timeless piano lacquer, the La Diva is an eye-catcher in any home environment. However, it gets its special charm from the details made of solid aluminum. Both the base plate with its adjustable metal cone tips, which guarantee safe and precise stability on any surface, and the lateral struts, which protect the passive radiators from accidental contact, are made of high-tech material. All of this adds up to an overall weight of an impressive 49.8 kg per speaker, perfectly proportioned at 124 cm high, 38.5 cm wide and 46.5 cm deep.
