PRODUCT DESCRIPTION
The Concourse Q4(T) and Q5(T) are two-way high performance
speaker systems designed for distributed music, paging and
speech applications. They combine quality transducers with
sophisticated crossover designs in lightweight and durable ABS
enclosures and come complete with mounting brackets and
hardware.
CONCOURSE Q4
The Concourse Q4 is a two-way speaker system consisting of a 4"
low frequency driver and a 1" dome tweeter and is supplied with
a wall mounting bracket. There are four versions available:
• Concourse Q4W – White, 8Ω, 25 Watts
• Concourse Q4B – Black, 8Ω, 25 Watts
• Concourse Q4TW – White, 15 Watt 70/100 Volt
transformer included
• Concourse Q4TB – Black, 15 Watt 70/100 Volt
transformer included
CONCOURSE Q5
The Concourse Q5 is a two-way speaker system consisting of a 5"
low frequency driver and a 1" Dome tweeter and is supplied with
a wall mounting bracket. There are four versions available:
• Concourse Q5W – White, 8Ω, 35 Watts
• Concourse Q5B – Black, 8Ω, 35 Watts
• Concourse Q5TW – White, 25 Watt 70/100 Volt
transformer included
• Concourse Q5TB – Black, 25 Watt 70/100 Volt
transformer included
PRODUCT FEATURES
The Q4/Q5 models are fitted with 4 threaded inserts on the rear
for attaching the supplied mounting bracket. There are also two
threaded inserts to accommodate after-market brackets.
Amplifier outputs are is connected to the speaker through a termi-
nal strip mounted inside a recessed well on the rear of the speaker.

INSTALLATION
Step 1
Mount the bracket as shown to the wall or other mounting surface
using suitable screws.
Step 2
Mount the bracket with the threaded bolt to the cabinet using the
4 supplied screws.
Step 3
Place the rubber friction washer over the bolt.
Step 4
When you’re ready to install the speaker insert the bolt in the wall
bracket from below.
Step 5
Place the dome cover over the bolt.
Step 6
Place the lock washer and hex nut on the bolt. Tighten gently, aim
the speaker as needed and tighten firmly.
Step 7
Ensure that seismic restraint cable is firmly attached to both the
loudspeaker and an anchor point on the mounting surface.

LOW IMPEDANCE (8Ω) CONNECTIONS
Low impedance models are fitted with two terminals for the (+)
and (-) incoming amplifier feed and two terminals paralleled to the
next speaker.
Speakers may be wired in parallel as shown below. Ensure that
the total impedance of connected speakers does not fall below
the minimum impedance of the connected amplifier. The following
table shows the net impedance when several speakers are
combined in parallel.
Number of Speakers in Parallel Combined Impedance
1 8Ω
2 4Ω
3 2.6Ω
4 2Ω
70/100V CONNECTIONS
70/100V Models use one terminal for the Common (-) connection
and the other three terminals for the transformer power taps. Note
that the Q4T offers taps at 15W/7.5W/3.75W (below left) while
the Q5T offers taps at 25W/12.5W/6.25W (below right).

NOTE:
Power taps are labeled for 70V operation. Connection of 100V
amplifiers requires use of the next lower wattage tap to prevent
damage to the speaker. See chart below.

Connect speakers in parallel as shown below: Select the power tap by dividing the amplifier’s available power
by the number of speakers to be connected and then selecting the
next lower wattage tap. For example:
200W amplifier ÷ 20 speakers = 10 Watts; use the
7.5W terminal
Individual speakers may be tapped higher or lower in order to
better balance the system sound pressure level in different areas.
Ensure that the combined power draw does not exceed the
maximum rated power of the amplifier or damage to the amplifier
and speakers could occur.
CE COMPLIANCE
This product is in compliance with CE directives and bears the CE
mark. For detailed information on specific directives please contact
your local QUAD Industrial sales office or distributor.
