HS-615 HANGING SPEAKER
O w n e r s M a n u a l

Introduction
Congratulations on your purchase of an RBH Sound residential/commercial 70 Volt
compatible hanging speaker! Your speaker is the result of many years of research
and development dedicated to producing high quality products for home audio
and audio/video systems.
This manual contains features, installation procedures and specifications for
the HS-615 residential/commercial 70 Volt compatible hanging speaker. It is
recommended you thoroughly read through the material contained in this manual
before connecting your speaker. This will ensure that you have an understanding
of how to install the speaker for optimum performance.
Break-in Period
Allow 10-15 hours of listening time to adequately break-in the speaker. As the
speaker breaks-in, the driver suspension will loosen. The result of break-in will be
an increase in low frequency response, improved definition, and increased clarity
and detail.
Care and Cleaning
To maintain speaker appearance, clean with a damp soft cloth.
Features
The RBH Sound HS-615 hanging speaker incorporates a poly-resin enclosure to
reinforce bass frequencies allowing a more controlled bass response, and utilizes
an acoustic suspension design while offering operation in either 8 Ohm or 70
Volt modes.
A powerful magnet gives the bass/midrange driver high power handing capability.
This ensures accurate dynamic reproduction. The tweeter features liquid cooling to
also allow greater power handling.
Steep acoustic slope crossovers are used to integrate drivers. The use of steep
crossover slopes allows high power handling, minimizes driver interaction
anomalies, and maximizes the clarity with which each driver is able to produce its
respective frequency band. Sophisticated computer modeling techniques are used
extensively in the RBH speaker design process.
A switch connected to the swivel tweeter allows the sound of your speaker
to be customized for each environment. This switch is located next to the
woofer on the front baffle of the speaker and has three positions: +3dB, 0,
and -3dB (see illustration on page 3). The +3 position increases output, and,

Features (continued)
the -3 position decreases the output of the tweeter relative to the woofer. The
0 position is the factory setting and generally provides the most natural response
from the speaker.
The use of a 70 Volt transformer allows several HS-615 speakers to be used together
by running a speaker wire from one speaker to the next in a parallel connection
when using a 70 Volt amplifier (as shown in the wiring diagram below).
WARNING: Refer to the wiring diagrams and voltage selector sections to
properly install a 70 Volt system.
Wiring Diagrams
CAUTION: If your amplifier isn’t capable of handling the impedance of all
connected speakers, this may result in overloading the amplifier and may cause
possible damage to the amplifier. Check your amplifier’s documentation for
proper impedance levels.
Parallel Connection
A parallel connection exists when speakers are connected directly to an amplifier
(as shown in the illustration below). Each speaker’s positive terminal is directly
connected to the amplifier’s positive terminal, and each negative terminal is
directly connected to the amplifier’s negative terminal. This type of connection
should be made when using a 70 Volt amplifier.
In this example, each speaker is set to
70 Volt operation and is being powered
by a 70 Volt amplifier. If the speakers
were set to 8 Ohm operation, the total
impedance (using Ohm’s Law) equals
(8 x 8) ÷ (8 + 8) or 4 Ohms, which
may be too low for some amplifiers.
Make sure to properly select 70 Volt
or 8 Ohm operation before connecting
the speakers to the amplifier.

Wiring Diagrams (continued)
Series Connection
A series connection exists when two or more speakers are connected together by
one wire. Typically, the negative connection of one speaker is connected to the
positive connection of the next speaker as shown in the illustration below. This
type of connection is reserved for certain 8 Ohm systems ONLY, and NOT FOR 70
VOLT OPERATION. Series connections should only be done with identical speakers
to avoid inconsistencies in sound quality.

Voltage Selector
As previously mentioned, the HS-615 can be used in a 70
Volt system or in an 8 Ohm system. The voltage
selector switch allows you to properly set the
speaker to 8 Ohm or 70 Volt operation.
The wattage selector switch allows
the choice of 2, 4, 8 or 16 watt taps
for 70 Volt operation. For 70 Volt
operation, be sure to correctly
set the wattage selector
switch so that the number
of speakers multiplied by
the wattage setting does
not exceed the power
output of the amplifier.
In this example, each speaker has a impedance of 8 Ohms. In a series connection as
shown here, the total impedance equals 8+8 or 16 Ohms. The total impedance of a
series connection is the sum of each speaker’s impedance.
