Designed to be mounted with integral keyhole, optional tilt/swivel bracket, or mounted behind screens. Sharing “trickle-down” technology from our flagship S-Series, the DPC-Array here based on three 26mm domes, guarantees excellent directivity control and timbre matching with all R-Series speakers. The Silk diaphragms developed ground up, chosen specifically their smooth, effortless representation of midrange and treble. The 165mm woofer is made from our proprietary HPF pulp, two years in development, bringing new technology to one of the oldest materials used in loudspeaker design. Optimized for smooth power response (2pi or 4pi) the R4s is designed to work well as part of a larger R-series system, versatile enough to be used as any channel.
