Quest Engineering’s Q-motion range of sound reinforcement loudspeakers has been expanded with the addition of the QM500 PA/monitor cabinet.

Quest Engineering QM 500The QM500 is a passive, two-way bass reflex design speaker suitable for mobile and installation allocations. The design characteristics of the QM500 make it well suited to both full-range use and 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° for horizontal, vertical or foldback monitor applications.

The asymmetrical coverage allows the horn to achieve both long-throw performance and wideangle 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.
