Radialstrahler System 101 X-Treme MKII

The crown jewel of MBL’s legendary product line, the 101 X-Treme system never fails to astonish – in looks or sound. The flagship transducer is comprised of two six-foot tall towers that each house a pair of MBL’s iconic Radialstrahler omni systems, flanked by another pair of six-foot subwoofer towers to create an extreme four tower system. Beyond their aural purity and objet d’art presence, each Radialstrahler tower features a pair of MBL’s proprietary high, mid, and low-frequency spherical drivers that capture the inimitable MBL audio signature.

Purposefully configured in a stunning vertical mirror array, the 101 X-Tremes distribute sound to every corner of your listening space. Meticulously hand-crafted from carbon fibre, copper, aluminum and magnesium, the revolutionary mirror array allows the 101 X-Treme to project music farther without increasing the volume.
