Radialstrahler 126

One of the most important and obvious technical strengths of the MBL 126 is that it uses the same vertically mounted spherical tweeter and midrange drivers as the MBL 101 – the iconic flagship loudspeaker that first garnered international recognition for MBL, and a reputation that stands to this day. The diminutive 126 Radialstrahler was specifically developed to create an astonishingly large soundscape in smaller listening rooms. Its pyramid shaped bass cabinet can’t break the laws of physics, but it pushes them to the last hertz with a specially constructed bass-reflex enclosure that reduces cabinet resonance and vibration.

With only 11 liters of volume, two 5.5” woofers configured in a push-push grouping on the sides of the cabinet make optimal use of their space to deliver in-room bass frequencies down to 70 Hz. The two bass drivers punch far above their weight with torsion-resistant aluminum membranes that maximize cone excursion. Held firmly in place by an aerodynamically shaped chassis, each of these powerful drivers enjoys maximum freedom of movement. The heat generated by the cones’ linear travel is efficiently dissipated from the driving voice coil via a directly glued voice coil carrier.
