All around perfect sound
The new 4PI PLUS.2 ribbon super-tweeter is an add-on component that creates a perfect, spacious sound impression when installed on conventional loudspeakers.
The combination of direct-radiating loudspeakers, providing precise location and imaging and the omni-directional 4PI PLUS.2 ribbon super-tweeter providing an open and airy sound, results in perfect spaciousness not found with any conventional loudspeaker.
360 degree omnidirectional ribbon tweeter yields a resonance-free upper cut-off frequency of 50 kHz and makes this tweeter an ideal component for the reproduction of SACD and DVD-A. Its impressive and silky sound quality gives rise to an airy sound quality.
Optimum settings of volume and cutoff frequency
The 4PI PLUS.2 offers an integrated network for perfect setting of its sensitivity in 5 stages (-4, -2, 0, +2, +4 dB) in order to optimise the combination with loudspeakers whose sensitivity may vary between 84 and 92 dB/2.83V/m.
Additionally, the lower cutoff frequency of the 4PI tweeter may be selected from 3 values (10, 12, and 15 kHz).
