MR 55 Two-way Loudspeaker 175-w

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.

MR 55 Two-way Loudspeaker 175-w

The shielded low-frequency driver¬ís carbon fiber diaphragm produces a linear response and low distortion. The high-frequency section features a 110° x 110° constant directivity horn with a built-in mechanical phase equalizer.

The horn is driven by a Ferrofluid® cooled,0.75" soft dome tweeter
