WARNING
When the Unit is in Use
• Turn down the amplifier before switching
on the amplifier. If there is no sound,
check the speaker connections. Speakon
connectors must be locked in place.
• Should any of the following irregularities
be found during use, immediately switch
off the amplifier power, disconnect the
power supply plug from the AC outlet and
contact your nearest Quest dealer:
• If you detect smoke or a strange smell
coming from the unit,
• If the unit falls and the unit case is
damaged,
• If it is malfunctioning (no HF or low
frequency output).
Make no further attempt to operate the unit if
it is found to be in any of the above conditions
as this may cause fire or electric shock.
When Installing the Unit
• Do not expose the unit to rain or an
environment where it may be exposed to
water or other liquids, as doing so may
result in damage to the bass driver or
corrosion of the steel protective grill.
• Do not cut, kink, otherwise damage
nor modify the speaker cable. Also use
speaker cable of at least 1.5mm core
diameter. In addition, avoid locating the
speaker cables close to heaters, high
traffic areas or locations where the cables
can be damaged.
• Avoid installing or mounting speaker
boxes in unstable locations and when
flying, use the hardware designed for the
speaker box and fix securely to a solid
wall. Failing to do so may result in the
unit falling, causing personal injury and/or
property damage.
• Be sure to ground to the safety ground
(earth) terminal to avoid electric shock.
Never ground to a gas pipe as a
catastrophic disaster may result.
• Never hang a speaker box from only
one rigging point. Use multiple points
and attach a safety line to a point strong
enough to take the weight of the speaker
box.
WARNING Flying the box from one insert must not be attempted!
Improper installation may result in damage, injury or death.

General Description
The HPI5 is an ultra compact full frequency
range multi-purpose 2-way passive speaker
system designed for discrete very high fidelity
audio installations where a low visual profile
yet high output is required.
It is suited to full range front-of house sound
for short and mid throw applications in both
stand alone applications or in a distributed
system. (See HPI Series bass speaker
systems).
The HPI5, like all speakers in the HPI Series
have been designed to perform perfectly
without the requirement of dedicated system
processors.
Features
The HPI5 has a number of features designed
to increase performance and versatility for a
professional sound installation environment.
A great deal of attention was paid to the
details of the design to make the HPI5 both
sonically impressive and functionally suited
to all aspects of ultra compact mobile and
permanently installed sound reinforcement.
High Powered Purpose Designed
Components
A powerful 1” diaphragm high frequency
driver matched to a Quest designed mid/
short throw horn flare delivers a hi fidelity
high frequency response with a medium throw
capability.
The HPI5 is a bass-reflex design where the
porting is specifically dimensioned to match
the low frequency range capabilities of the
high powered 5” transducer, despite the
relatively small dimensions of the driver and
the enclosure.
Exceptional vocal and midrange response
makes the HPI5 an exceptional performer
when it comes to vocal projection and
reproduction of acoustic instrumentation.
Functional Design
Not just stylish, but practical. The recessed
input panel and innovative installation
bracketing system allows a visually tidy
installation in both vertical and horizontal
installation. The speaker impedance of 16
ohms means that 4 units can be connected to
each channel of a 4 ohm minimum amplifier.
Solid Build Construction
Built for long life in high heavy duty cycle
environments, the HPI5 is well suited to all
professional applications. The ply timber
casing, high powered components and heavy
gauge power-coated steel grill make the HPI5
“a tough package for a tough world”.

Connections
Two Neutric Speakon model NL-4 connectors
are mounted in a recessed panel on the
rear surface of the box. This allows the
speaker box to be set flat against a wall
without physical interference to the speaker
connector.
• The connector input is wired pin 1+ and
pin 1-
• Pin 2 is not connected
Take care when inserting the Speakon
connector twisting the connector until it
locks into place. Reverse the procedure to
disconnect.
Getting The Best From Your HPI5
Suitable Amplification
The HPI5 is an 16 ohm enclosure and can be
connected in multiple parallel connections to
an amplifier channel. In the case of a 4 ohm
minimum amplifier, this means that four HPI5
speakers can be connected to each channel.
The HPI5 is a mid power level high efficiency
system, so ultra high power is not necessary
to obtain high sound pressure levels. The
recommended power range per amplifier
channel is 350-450 watts RMS into an 8 ohm
load or up to 900/1,000 watts RMS into a 4
ohm load. The HPI5 will work well with the
Quest QA2004/3004 amplifiers. The QM1000P
sub/satellite amplifier can also be employed
when a compact amplifier installation is
required to power a 4 x HPI5 and 2 x HPI12S
system.
Setting the QA amplifier’s high pass filter at
80Hz if the system will be driven hard in a full
range application. If you are intending to add
sub bass speakers or use for mainly vocal
reproduction, the high pass filter should also
be set to 80Hz.
