Heco Superior 840 speakers

"Superior" by Heco is the loudspeaker range for audiophiles who cherish excellent sound and intelligent design for small as well as for larger rooms. "Superior" means sophisticated technology down to the smallest detail. And the bigger the speaker, the more power handling and growing deep bass reproduction. Dynamics and sound intensity increase. Allow your amplifier to shine; with a punchy bass, tight midrange and brilliant highs. Heco "Superior"; that stands for undistorted reproduction of sound, perfectly musical - for all those who love the extraordinary.

Woofer Chassis

The woofer is constructed on an extremely stiff chassis made of pressure-cast light metals. The cone diaphragm is made of a quality multilayer cellulose material, coated with a special synthetic layer for damping. The small, lightweight coils, made of best copper wire and which are therefore extremely low in resonance, feature a high constant power handling. In the case of floor standing speakers, the double woofers are pneumatically isolated from one another by means of separate chambers.

Cone Mid-Range Speaker

The range of fundamental tones between 300 and 3000 Hz, to which the human ear is particularly susceptible, have to be transmitted with the ulmost phase linearity. That is why this range is being reproduced by a sole driver a newly developed phaselinear basic speaker with an absolutely neutral sound Polypropylene diaphragm. With the interior 230 S the supronyl-dome-diaphragm has proved successful.

Tweeter Dome

For the high-ranges a special metal dome made of aluminium-mahganese is being used. The light, single-layer voice coils, the highly flexible supronyl suspension and its diffusor with pressure chamber effect allow the enormous range of 2 to 20 kHz. From the musical point of view this means high brilliance, impulse fidelity and great resistance without any sharpness in the reproduction of high frequencies.

Frequency Cross-over

The frequency crossover design shows an intelligent and ingenious construction in order to achieve minimum loss without any additional distortion during signal transmission. In practice this means.

An ingenious combination of air - core and ferrite-core coils, polyester capacitors and high-quality electrolytic capacitors with tight tolerances. The precision mounting of the components onto the circuit board with its engraved conductors ensure optimum decoupling of the components from each other.

Heco Superior 740 loudspeakers

About The Aesthetics Of Sound

Just as serious listeners will strive for aural perfection, so Heco have added the dimension of visual perfection. This creates a harmonious product.

Heco is standing at the crossroads of science, technology and art.. The aim is demanding - to achieve the perfect, neutral reproduction of sound and to present it in a high-class design.

This has been a constant channenge; requiring knowledge, experience and creativity.

Heco has been building loudspeakers for many years and we have now come near to the ideal, both in aesthetics and in sound. A highly qualified staff along with advanced manufacturing procedures and innovative technology has been needed to achieve this. The result - a sound performance which equals the joy of art - today and tomorrow.

Integrated Subwoofer System ISS

Heco's new ISS technology skillfully blends and integrates an entire subwoofer system into each loudspeaker it incorporates a totally separte acoustic volume chamber within the cabinet and steep low-pass filtering for the subwoofer signal (18 dB/octave slope to 24 dB/octave slope according to model) with decoupling between 150 Hz and 250 Hz. All Superior models 9excepting the Superior 620) and the Interior models 330 S, 430 S, and 535 s can therefore be considered  as "cum basso continuo system" . The driver itself is suspended in a rigid casting of solid aluminium with a polypropylene cone.

Wide Bandwidth Midrange

When you listen to music the most critical area is the midrange, the frequencies between 300 and 3000 Hz. If this area is not correct, even the best woofers and tweeters can not save the sound.

Heco research has developed a new technology to reproduce this crucial region of music a new midrange driver which covers this entire range alone - without having to cross over to the woofer or tweeter

This design produces absolutely perfect phase coherency throughout the region. You can hear the result; smooth, clear natural voices and instruments.

Aluminium-manganese dome tweeter

Heco use their finest metal dome tweeters in the "Superior" and "Interior" models. Developed and manufactured by Heco, these drivers have exce[tional frequency response and power handling as well as a wide dispersion. They ensure smooth upper frequencies.

Heco Precision 400 loudspeaker

Heco precision Series loudspeakers feature a patented woofer duet claimed to ensure accurae bass response. For prcise midrange and high frequency sound, both soft dome midrange drivers and tweeters utilize a special polymer material made exclusively for Heco.

To prevent the effects of spurious vibrations, the acoustic suspension cabinets are built of particle board that is "five times more dense than usually used for speaker cabinets".

All models have two environmental contour controls, a nominal DC impedance of 8 ohms, and an efficiency control rated at 91 dB/SPL at 1 m/1W.
