MBL 101D Radialstrahler


The MBL 101D is a four way omni-directional speaker. Instead of a single pulsating sphere, it uses one pulsating woofer, one pulsating spheroid midrange unit, one pulsating spheroid tweeter and one non-pulsating 12-inch cone subwoofer. The square tapered subwoofer enclosure rises to support the radial woofer speaker standing on end.

A control panel with different setting possibilities is located at the back of the speaker, on the crossover housing. Three jumpers allow for adjustment of the tonal balance. Both high-range, mid-range and bass energy are adjustable.

Including MBL wooden transport crates and manual. Now available for 13.900 euro.
