Conussen with wood fiber The embedded wood fibers give the cone an irregular surface structure, which reduces the resonance of the surface dramatically. This ensures the best possible display of each detail in the audio signal. Soft Dome Tweeter The Dome Tweeter delivers the best resolution in its class, with a continuous frequency range, a wide range and little coloring. A clear legacy of our high-end series. The tweeter is based on ultra lightweight woven textile that weighs less than half than the standard on the market (0.056mg / mm2). Product Details DALI ALTECO C-1 is, both in terms of design and function, a multifunctional speaker. DALI wanted to be sure that the ALTECO C-1 as a high life speaker, but also as a traditional stereo speaker can be used. By designing the exchange filter for stereo use, and strictly by us DALI Keeping noise principles, we have made a loudspeaker that meets both conditions. It is the perfect solution for adding height information to a surround arrangement, or to assume the role of a discrete stereo speaker. The ALTECO C-1 provides credible high-quality information at ATMOS, DTS-X and Auro-3D films in a surround arrangement - not only when it rings upwards and used the ceiling as a reflector, but also when it rings down from a high position just Under the ceiling. The ALTECO C-1 may even be the special filtering that is used to enhance the effect of HRTF technology (Head Related Transfer Function), a technology used in ATMOS certified speakers. Instead, the ALTECO C-1 only to the height processing that takes place in the surround amplifier when that mode is selected. If we have the non-linear HRTF filtering in the ALTECO C-1 had applied it was impossible to use it as a versatile, neutral speaker, so that his use would be limited to an upstream loudspeaker. Due to the way it has been designed, the DALI ALTECO C-1 The best of different worlds, with ultimate flexibility and multiple applicability.
