[. . . ] The reason for this is the high degree of sensitivity of the human ear, particularly in the vocal range. The finest solution here is a combination of a highquality paper cone with an Alnico magnet. Alnico (Aluminium - Nickel - Cobalt) is a material that can absorb extremely high magnetic field strengths and has high temperature stability. Music lovers especially appreciate the repeatedly referred to acoustic advantages in terms of dynamics and resolution. [. . . ] the midrange is the most important frequency range for evaluating the naturalness of a loudspeaker. Two 200 mm long-stroke subwoofers take care of the bass range below 200 Hertz. The material used for the cones is also Kraft paper, as for the midrange drive unit. A large carbon-fibre dust cap gives the subwoofer chassis additional rigidity. Combined with a long-stroke rubber bead and the symmetrical doubleferrite drive, a chassis is produced which can also reproduce extremely low frequencies with high dynamics and precision. The treble range is taken care of by a handselected nano-tweeter with a dampened resonance chamber. The 25 mm woven fabric calotte is coated with carbon-based nanoparticles, guaranteeing an extremely clear frequency response curve up to 50 kHz. The calotte, driven by a double magnet system, is located in an aluminium flange with a short horn projection of better acoustic coupling. The connecting strip with the large gold-plated terminals is also new. In addition to being compatible with triwiring and tri-amping, it also has other individualisation options. The treble and midrange levels can be adapted to the respective room conditions, for example, and be increased or lowered by +2 or -2 dB respectively. Another important part is the crossover with impedance linearization elaborately designed for Heco's "The Statement" model and equipped with exacting tolerance components, such as MKP condensers and MOX resistors. For optimum vibration isolation, the Heco Statement stands on heavy full-metal spikes and matching floor plates with an absorbent damping element. The enclosure of Heco's "The Statement" is made of MDF with elaborate bracing inside. The lacquer finish in silver or black is of the same high quality as the care given to the development and design of the individual components. Almost 60 years' of proficiency in the design of loudspeakers speaks for itself ­ 60 years of research and development, with the aim of making music reproduction an unforgettable experience. "The Statement" from HECO is reminiscent of this long period of involvement in the design of loudspeakers. A clear "Statement" for good sound, for music and more a fantastic experience. These high standards are also met by the matching active subwoofer of the range. Equipped with a 300 mm, highperformance, bass driver under the control of a 400 watt power amplifier, this 35 kg low frequency transducer covers from 20 to 150 Hz and allows full adjustment of output level, crossover frequency and phase. This ensures it can be optimally adapted to all requirements. Whether your desired application is in the high-end 2 channel stereo sector or for a sophisticated home theatre installation the active subwoofer, perhaps in combination with the Celan XT centre speaker, allows every requirement to be met. [. . . ] The centre unit is magnetically shielded as well as being optimised for best possible speech reproduction. The active subwoofer, classically designed as a front firing unit, is the dedicated to the reproduction of accurate bass. Its integral power amp has an output of 300 watts, sufficient to exert absolute control over the long throw 250 mm subwoofer with its toughened paper cone and die-cast aluminium chassis. Flow-optimised bass reflex ports are bolted to the cabinet allowing the subwoofer to breathe freely without unwanted turbulence. [. . . ]
