Three-way, omnidirectional, floorstanding loudspeaker.
The MBL 101C uses three radically-shaped dynamic drivers, stacked in a column and radiating in a true 360 degree pattern (radialstrahler principle). The speakers have no front or back, other than the positioning of the logo badge. The drivers all work on the same principle, acting as pulsating spheres, but differ in size and material. At the bottom of the stack is the large woofer driver, next is the mid driver and, capping it all, the tweeter. The tweeter and midrange Radialstrahlers are made from vertical sections consisting of carbon-fibre strips (what MBL calls “lamellas”), hand-assembled and pressed into a special former under high pressure and high temperature. The voice coils are fitted to the bottom openings of these orange-shaped modules, the voice coil carriers made of aluminium and floating in ferrofluid cooling material move up and down, and the lamellas of the spherical driver are driven. The big tulipbulb woofer is formed of laminated aluminium wedges, each reinforced with metal struts, and with its voice coil and suspension at the bottom. The entire assembly rests on a cast aluminium plinth, finished in an automotive-grade anthracite metallic paint. The plinth also houses a passive fourth order Linkwitz-Riley crossover network which guarantees the phase linear distribution of the electric oscillation. The Radialstrahler`s sound qualities are so outstanding that listener positioning turns out to be of minor importance. Speakers with an uncolored, neutral and homogeneous sound and that have a three-dimensional character. Specifications: Crossover frequencies: 600Hz, 3.5kHz. Acoustic center: central axis (Hilbert transformation). Frequency range: 38Hz-80kHz. Sensitivity: 80dB/W/m. Nominal impedance: 4 ohms. Nominal power handling: 200W, 1.1kW peak. . Woofer System: Al/Mg Alloy, black anodized coil, hi-temp wire, hi-temp glue. Connectors: Six binding posts for wires or plugs (tri-wiring/tri/tri-amping). Remarks: Some dents on the lower bases.
