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.
