coverage patterns with either 12" or 15" low-frequency drivers. Models include the MD-F122/64r, MD-F122/94r, MD-F122/124r, MD-F152/64r, MD-F152/94r and MD-F152/124r. Two low-frequency models with single

2-way models can be operated in either full-passive or bi-amplified mode

The MD Series is available in either black or white finishes
15" and 18" transducers are the MD-L115 and MD-L118 respectively. All these models share the same 35" tall, 30° trapezoidal enclosure.
All full-range models feature a rotatable

System enclosures employ the same dimensions and 15 attachment points

All models constructed in a trapezoidal design of multi-ply Birch with a powder coated steel grille

When employing the 60° horn, the 30° trapezoidal angles minimize negative interference between tight-packed enclosures
