About HECO

HECO – German HIFI since 1949

HECO is a brand name that represents a rich and long tradition in German speaker production. Since the day the company was founded more than six decades ago, it has been committed to developing an uncompromising, high quality reproduction of music in a home environment.



Legendary speaker series have shaped the image of the brand to date. The fact that HECO has reinvented itself time and again over more than sixty years of its history - spanning a period that has witnessed some of the most important developments in hi-fi technology - is a testament to the strength and innovative power of the brand.


Countless accolades and test victories are proof of this passion for perfection. We combine our expertise to produce outstanding products.

German HIFI since 1949 – and still ahead of the times.

Philosophy

It's only the result that counts - this seemingly simple product philosophy has been pursued by HECO for decades to ensure its prominent position at the forefront of German speaker development. The objective is to produce a perfectly balanced, transparent and dynamic sound. HECO's virtues: We spare no expense if we realise there is a potential for improvement - this goes for development, material quality and the use of technology. This has resulted in the continuous emergence of new concepts over the decades that have become milestones in the speaker industry. The fact that we continue to develop products with an unrivaled price-performance ratio despite this continuous development has been put in black and white by the trade press and our customers. We are proud of everything that HECO stands for - just like our customers.

Kraft paper cone

HECO TECHNOLOGY –Tradition & High-Tech

AlNiCo-midrange driver

The top-of-the range speaker „THE NEW STATEMTENT“ is equipped with an AlNiCo
midrange - which is very important for the naturalness and precision of the midrange
reproduction. The midrange is the crucial region in realizing the goal of a naturalsounding loudspeaker. The reason for this is the high degree of sensitivity of the human ear, particularly in the vocal range.The finest solution is a combination of a high-quality paper cone with an AlNiCo magnet. AlNiCo (Aluminium - Nickel - Cobalt) is a material that can carry extremely high magnetic field strengths and has a high temperature stability. Music lovers especially appreciate the repeatedly referred to acoustic advantages in terms of dynamics and resolution. However, the extremely high price and, in particular, the difficulties inherent in the production of consistent AlNiCo have been responsible for it not being widely used these days.
After considerable research over a prolonged period HECO’s engineers have now
managed to develop an AlNiCo powered drive unit which, with the help of modern
laser technology (Klippel® system) and the “Finite Element Method” has resulted in a
loudspeaker that works symmetrically with regard to its magnetic field, suspension and inductance. The acoustic conversion takes place via a lightweight "kraft paper cone" coupled with a relatively stiff and fast suspension system. The result is a remarkably low level of distortion and an amazingly natural midrange reproduction.

Die-cast aluminium chassis

Kraft paper cone

The “Kraft paper cone” is the high tech cone of the HECO midrange speakers and woofers satisfies the most extreme of acoustic demands. Music lovers often prefer the particularly natural sound produced by high-quality paper-based cones. Indeed, many of the legendary cinema and high-end loudspeakers of the past used paper cones for that very reason. It’s perhaps explained by the particularly good ratio between low weight and high self damping. Specific types of wood are pre-selected to provide this high quality pulp. Only Nordic pine timber has the required strong fibres. Other woods and cheaper waste paper are excluded because of their low strength. The pulp is then mixed with the addition of 5% Germanproduced wool fibres (6 - 12 mm long). During this process all of the fibres interlock to form a densely conjoined weave. This material is then pressed evenly into the conical form of the cone under high pressure. The result of this is a loudspeaker diaphragm with the desired acoustic properties for high mechanical loading. These positive attributes mean that the “Kraft paper cone” is used in practically all of
HECO‘s loudspeakers. The long throw surround, highly durable voice coil and linearised magnet systems combine to guarantee maximum dynamic contrast and precision.

High Energy Tweeter

Die-cast aluminium chassis

The multi-ventilated die-cast aluminium chassis have extremely well controlled resonance characteristics and as a result provide the utmost stability. They genuinely offer the best possible foundation upon which the powerful magnets and paper cones can perform. However, in a purely aesthetic sense the aluminium baskets also exude precision with their diamond polished surfaces hinting at the purity of sound the speakers can deliver as a complete system.

Cabinet

High Energy Tweeter

The HECO Research & Development team has developed a new tweeter which is characterised by high efficiency and exceptional resolution for the HECO Celan GT series. It is based on a 30-mm diameter dome possessing a wide surround conferring a particularly low resonance frequency. The design increases its capability to disperse energy particularly at the transition to the mid-range and thus allows an especially harmonious blend at these critical frequencies.  The dome is made from a very light polyfibre compound to enable it to reproduce the highest of frequencies. Copper rings integrated within the magnetic circuit reduce distortion while the carefully profiled, diamond-cut die-cast aluminium flange is responsible for the very controlled,
wide and even dispersion from this new tweeter.

Cabinet

The perfect loudspeaker cabinet should contribute the least possible resonance. This is why HECO uses high quality MDF instead of cheaper chipboard. An asymmetric cabinet profile also reduces unwanted internal standing waves. All of the cabinets feature extensive multiple bracing to reduce panel resonance. To ensure perfect and secure location on differing floor types, all of the free-standing speakers are supplied with height-adjustable spikes and rubber feet.
