4Pi Tweeter

Unfettered spatial realism.

Placing the omnidirectional 4Pi Plus.2 ribbon super-tweeter on top of your main, direct-radiating loudspeakers results in perfect spaciousness not found with any conventional loudspeaker. Equipped with flexible options for adjusting sensitivity and the lower cutoff frequency, the 4Pi Plus.2 can be seamlessly integrated with virtually any loudspeaker. It enables the sound to break free from the loudspeakers and fill the entire room. All without the need for additional amplification.

      • 4Pi technology
        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 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.
