Compact High-definition Loudspeaker
The HPI111 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.
The HPI111 is available in black (HPI111) or white (HPI111W) low sheen finish.
Rigging & Accessories
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 "single box top spine hanging bracket" system for single speaker systems, progressing to QR2 pan tilt wall bracket and QR3 two box hang. A QR Series U bracket is also available for single box horizontal installation. The QR3 hanging plate has multiple splay angle options to allow precise horizontal dispersion control.
Thanks to the 90 degree dispersion of the of the HPI 111, the QR3 hanging bracket suspending two HPI111 boxes can cover a full 180 degrees.
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.
Power Me Up
The HPI111 can take serious power by any standard. Quest Engineering recommends an amplifier capable of delivering 480-720W (nominal) to ensure full performance. The perfect solution are Quest's QA3004, QA4004 or the new QX4500
Putting Energy Where it's 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.
The benefits of Quest asymmetrical projection – Get higher vocal intelligibility
- The acoustic energy is directed to where you want it (the audience), and not to the reflective surfaces around the room.
- The nature of the asymmetrical projection is a more efficient use of the energy. Consonant sounds are not drowned out by reverberant energy.
- The sound coverage and vocal image is more uniform throughout the listening area and high frequency component is less likely to “fall off” over distance.
