About the 111E

The MBL 111E is a four-way, omnidirectional floorstanding loudspeaker using MBL’s Radialstrahler technology. Its woofer section is bandpass-loaded, and the speaker is specified with a 29 Hz–40 kHz frequency range, 4-ohm nominal impedance, 83 dB sensitivity, and maximum sound pressure of 106 dB. The published crossover frequencies are 130 Hz, 600 Hz, and 3.5 kHz. It measures approximately 45 × 120 × 45 cm and weighs about 60 kg. The 111E is an earlier model distinct from the later 111 F; specifications and driver details associated specifically with the 111 F should not be attributed to this model.
