R852MD model, 15cm bass drivers. Just learned: When Monitor Audio launched its R852MD loudspeaker the first model to incorporate a metal dome tweeter – it caused quite a stir. Until that time, most metal domes were single-metal types made from copper or titanium and virtually all sounded unconvincing. The R852 used an aluminium-magnesium alloy dome and sounded significantly better and smoother than all of its single-metal rivals. It also incorporated ferro-fluid damping/cooling of the metal voice-coil former and a vented voice coil mechanism for better heat dissipation. These radical design elements formed the basis for successive generations of C-CAM metal domes.

-::- Crossover point : 3.5kHz [18dB/octave]
-::- Sensitivity : 98dB max at 1m, 20W for 96dB at 1m
-::- Impedance : 8 ohms nominal
-::- Recommended power : 8 to 30 watts
-::- Cabinet : bass reflex, high density 17mm wall thickness with polyester filling and polurethane foam absorption filling
-::- Dimensions [W x H x D] : 228 x 405 x 203mm
