Morel MDM 55 Midrange
The Morel MDM 55 is a hybrid 54mm (2") soft dome midrange drive unit from the Classic series. This hand assembled unit has a low resonance of just 380 Hz and a wide linear bandwidth, the response between 2-5 kHz is flat ± 2dB or better. This unit has a very compact square faceplate allowing close spacing of drivers.
Features include an Acuflex hand coated soft textile dome, 54mm Hexatech aluminium voice coil, a vented hybrid mixed magnet assembly and a critically tuned and damped aluminium rear chamber.
Power handling is excellent at 200w nominal, 1000w peak. As usual with Morel products, design and build quality are top notch.
