Quest Engineering releases the QM 500 Speaker System

Building on the high standard of excellent sound and real world reliability, the QM500 has made its way into Quest's Q-motion range.

The QM500 is a passive two way bass reflex design speaker suitable for mobile or installation use. The design characteristics of the QM500 make it ideal for both full range use or as the high-mid component of a multi way system with sub-bass enhancement.

The patented phase device high frequency transducer is matched to a rotatable asymmetrical wave guide that can be rotated through 270 degrees for horizontal, vertical or fold-back monitor applications.

The asymmetrical coverage allows the horn to achieve both long throw performance and wide angle close coverage without creating "hot zones" or adding to unnecessary room reflections that can degrade vocal intelligibility. The unit can be used in a standalone configuration or as part of a system coupled with any Quest sub-bass speaker as part of a high performance multi way audio system.
