Compact full-range speaker features, careful acoustic design and the use of advanced materials contribute to the exceptional music fidelity and speech intelligibility exhibited by the RCF monitor 55 (black) and monitor 55W (white) two-way speaker systems. The shielded low-frequency driver’s carbon fiber diaphragm produces a linear response and low distortion. The high-frequency section features a 110° x 110° constant directivity horn with builtin mechanical phase equalizer. The horn is driven by a Ferrofluid cooled, 0.75” soft dome tweeter.
