HPI Series High Performance Installation

A new approach to an old problem

Both old and new venues are rarely designed for easy audio installation. The very compact size and high power output of the HPI range is a low visual profile solution for most public spaces where high fidelity and voice intelligibility is required. The design benefits of light weight and high power make the HPI products also make a great mobile A/V and live production partner.

Putting the energy where it is needed

Quest has refined the technical art of asymmetrical audio projection for the HPI110/111 loudspeakers – Locating the sound where the audience is, and not to the walls and ceilings. The result is high intelligibility vocal imaging in reverberant venues. Whether an array or single box system, installation is simple and functional.

Small boxes that pack a punch

Mission designed as the “invisible audio” solution. As high power handling elements for a stand alone or distributed system. True fidelity voice and music at high sound pressure levels is possible, without the big box distracting visuals. Multiple rigging options allow HPI to reach its full potential.
