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.
