The new Kevlar driver is designed specifically for the K3 model and features not only powerful, dynamic and deep bass, but also a clear, unpainted midrange. The K3 model uses two such drivers, as well as one ribbon tweeter, which has proven itself in previous models, placed symmetrically between them in the center of the speaker. The ProAc Kevlar K3 ribbon tweeter has the lightest aperture, allowing you to transmit the most subtle microdynamic effects.
