The QUEST HPi 111 is a medium to high powered 90 degree dispersion compact speaker system designed to project voice and music throughout mid sized performance venues. It can be hung in small arrays or function as a stand alone speaker system in mobile PA production with or without sub bass enhancement. Contained within the discrete HPI111 appearance there are a number of key technical innovations to improve performance in real venue environments.
A Closer Look
The HPI111 system is comprised of a single 1″ 90 degree asymmetrical wave guide and one 10″ high powered woofer. The HF can be rotated to deliver optimum coverage in both vertical and horizontal installations. This makes the HPI111 very function in a wide variety of installation environments for both vertical and horizontal installation.
The HPI111 is the perfect candidate for a myriad of applications including performing arts centres, houses of worship, corporate theatres and venue environments where mid level SPL coupled with high definition vocal reproduction is required.
Hanging High with QR
To get the best from the HPI111 system, the multi-purpose light weight QR flying/installation system extends the range of installation options. The rigging system is progressive with its “top spine hanging bracket” system for single speaker systems.
Additionally, various attachments can be connected to make up almost any type of pan/tilt wall mount, truss mount or multi-box hanging array. Due to the 90 degree dispersion of the system the QR3 hanging bracket suspending two HPI111 boxes will cover a full 180 degrees, and a further widening of coverage is possible on this system. Horizontal installation is also possible with the HPI110 – ACHPIWB110 bracket.
Perfect for Unfriendly Environments
Bearing in mind most venue architecture is inclined to degrade the performance of standard sound systems. A common problem in many venues is reproducing intelligible voice. The degrading effect of wall and ceiling reflections causes loss of speech intelligibility.
The location in a room where the reflections are approaching the level of the sound system is known as “the critical distance”. The HPI111 system extends the “critical distance” by utilizing a custom HF wave guide.
The design of the asymmetrical HF wave guide is such that it directs the sound away from the walls and ceiling. Sound is directed only where it is needed and away from the reflective surfaces of the venue. The result is exceptional vocal clarity and control over the dispersion area.
