Quest - HPI110 - 10" Passive Cabinet that is GREAT for Vocals.


Compact High-definition Loudspeaker

Either mobile live sound or permanent installation; the HPI110 is a lightweight high powered compact speaker system that has a number of key technical innovations to improve performance in real venue environments. Most venues potentially degrade the performance of standard sound systems regardless of the quality. The HPI110 can be installed as a single element or as part of an array of up to three elements. Everything about the HPI110 shows a design aimed at functionality in the real world.

A Closer Look

Functionality in the real world is what separates the HPI110 from the rest of the field.

Have a bad sounding venue space? You need the HPI110. One consistent problem in reproducing intelligible voice in a venue is the degrading effect of wall and ceiling reflections. When a listener hears more sound from the reflected (reverberant) field than the primary sound system, loss of speech intelligibility results. This location in the room is known as "beyond the critical distance". The HPI system extends the "critical distance" by utilising a custom HF wave guide to direct the sound away from the walls and ceiling and into the listener area.

The HPI110 mid-high asymmetrical wave guide provides 60 degrees horizontal dispersion at the base of the flare and 30 degrees at the top. Vertical dispersion above the box is limited to 15 degrees. A large format HF driver allows for a relatively low cross-over frequency and this means more control over a wider frequency area.

The HPI110 is available in black (HPI110) or white (HPI110W) low sheen finish.

Rigging & Accessories

To get the best from the HPI110, the QR rigging system allows installation from a single box to three box arrays. With an array of three HPI110 speakers weighing in at 47kg, it's one of the most light-weight yet high powered systems in the world. This is particularly important if installation is required in a heritage building or an existing space with weight restrictions.

The rigging system is progressive with its "top spine hanging bracket" system for single speaker systems, QR2 wall bracket, QR3/4 for flown installations and a U bracket that can be direct wall or truss mounted.


Permanent or Portable

The HPI110 is at home on the road. The lightweight ergonomic design makes it ideal for portable mobile audio. A pair of HPI110 boxes on a "T" piece can be located on a sub bass box with a conventional speaker pole for mobile full range sound. The high power handling and projection characteristics mean a two box array can push a lot of high SPL audio into a medium sized venue space. The long throw characteristics of the system can deliver a surprisingly coherent result at 48 metres, which is outstanding for such a physically small speaker system.

In its most basic form, no system controller or complex system correction electronics is needed to get great sonic results from the HPI110. Just plug it on and play. With lightweight, high power and system scalability, the HPI110 is a truly versatile system.

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

  1. The acoustic energy is directed to where you want it (the audience), and not to the reflective surfaces around the room.
  2. The nature of the asymmetrical projection is a more efficient use of the energy. Consonant sounds are not drowned out by reverberant energy.?
  3. 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.

Power Me Up

The HPI110 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 or the new QX4500.
