About Telex QRx 212/75

The Electro-Voice QRX 212/75 Dual 12" 2-Way Full-Range Black Loudspeaker (Single) is two-way, full-range loudspeaker system incorporating two 12" woofers and a 3" voice coil compression driver on an asymmetrical 75-degree x 50-degree fully rotatable constant-directivity horn. In factory delivered position, this provides a 15-degree up/35-degree down vertical coverage pattern. The trapezoidal cabinet design allows this main PA system cabinet to easily conform to multi-cabinet arrangements or limited space clearances without sacrificing internal volume. The fully rotatable horn means regardless of cabinet position, pattern control is user-determined.

The QRX-212/75 is a good solution for medium size rooms and audiences as a main PA providing moderate levels with good bass response and added punch in the lower and mid frequencies, satisfying most DJ and live band applications. The asymmetrical horn can allow a single box to more adequately direct the high frequencies as needed, as well as streamline multi-cabinet arrays when rotated by extending horizontal coverage while minimizing overlapping and allowing tighter packs between the cabinets.

What's in the box:

  • Electro-Voice QRx 212/75 Dual 12 " 2-Way Full-Range Loudspeaker
  • 3x SST-1 Single Stud
  • Electro-Voice 3 Year Warranty
