Immerse yourself in music the ELAC 4Pi ribbon tweeter reproduces high frequencies in 360-degree surround sound, adding an incredible illusion of spaciousness to every piece of music. The 360-degree omnidirectional ribbon tweeter yields a resonance-free upper cut-off frequency of 53 kHz and makes this tweeter an ideal component for the reproduction of Hi-Res, SACD and DVD-A source material. Its’ impressive and silky sound quality lends realistic air to voices and complex recordings.
The design principle incorporates an 0.006 mm aluminum ribbon to form the membrane, ultra-light in weight with an extremely high sensitivity. When a current passes this membrane, it expands and contracts like a breathing cylinder. Driven by a strong neodymium magnet system, the flexible ribbon yields exceptional response that is flat well beyond the limits of human hearing but essential to the accurate reproduction of ambience and hence, musical realism.
