Unpacking

All Wharfedale Pro products are fully checked
before leaving the factory. After unpacking
please inspect cabinets for any physical

damage. Please retain the shipping carton if
possible and internal packing material in case the unit needs to be returned.
Please check as soon as possible the unit is functioning. In the event of any
damage please contact your dealer immediately so that a written claim for
damages can be made.

Operating/Use

1. The SI Series accept cables with Speakon™ and bare wire and

feature two Speakon™ type connectors and a barrier strip
situated at the rear of each cabinet. These are connected in
parallel. Take care to avoid adding too many SI
speaker systems in series (this does not apply to 64T). Each
series connected speaker increases the load on the amplifier and
can add up to a total load that may exceed the amplifier’s
capabilities, leading to possible damage. Two 8 Ω loudspeakers in
series make a 4Ω total load. Four 8Ω series connected
loudspeakers make a total load of 2Ω, which is too low for many
amplifiers.

2. Attach the speaker cable securely to your SI Series unit
and power amplifier (the amplifier should be off, power down
mode). Where possible use Speakon™ connectors as they are
professional high current connections specifically designed for this
application. Try to use the correct type of speaker cable according
to the handling ability of your SI Series Cabinet. Use 2
core equal stranded insulated cable for speaker runs. It is always
advisable to use heavier conductor cables on longer runs.

3. If using Speakon™, insert the speakon and rotate 1/8 of a turn until
locked in. If using the barrier strip ensure the correct phase
connection and secure with a Pozi-drive™/flat head screw driver.

4. Power up amplifier with levels on zero. Confirm units are operating.

 WARNING & SAFETY INSTRUCTIONS

1. READ INSTRUCTIONS carefully before operating this product.

2

.

RETAIN these instructions.

3. COMPLY WITH WARNINGS - All warnings and instructions for

this product should be adhered to.

4. USE WITH AMPLIFIERS - In order to avoid damage, it is
advisable to establish and follow a pattern for turning on and off
any sound system. With all system parts connected, turn on
source equipment, tape decks, instruments, mixers, signal
processors etc., BEFORE turning on your power amplifier.
Many products output turn on and turn off transients that can
damage speakers. By turning on your power amplifier LAST
and making sure the amplifier’s input controls are at minimum
any transients “upstream” of the amplifier are not amplified and
passed to the speaker. Wait until all system parts have
stabilised, then bring up amplifier controls to operating level.
This should take no more than a few seconds. Similarly when
shutting systems down, always turn down amplifier input
controls and then turn off your amplifier BEFORE shutting down
other components. Professional amplifiers often feature
delayed turn on/off circuits to perform these functions for you
automatically.

5. CABLES - Never use shielded or microphone cable for any
speaker connection as this will not be heavy enough to handle
the amplifier load and could cause damage to the complete
system.

6.

  RIGGING • SUSPENDING • MOUNTING

The rigging, suspension or mounting of this speaker system
can expose members of the public to serious health risks and
even death. UNDER NO CIRCUMSTANCES ATTEMPT TO
RIG, SUSPEND OR OTHERWISE MOUNT THIS SYSTEM
UNLESS YOU ARE FULLY QUALIFIED AND CERTIFIED TO
DO SO BY RELEVANT LOCAL, STATE AND NATIONAL
AUTHORITIES. ALL RELEVANT SAFETY REGULATIONS
MUST BE FOLLOWED. IF YOU ARE NOT PROPERLY

QUALIFIED OR DO NOT KNOW OF PERTINENT
REGULATIONS, CONSULT QUALIFIED PERSONNEL FOR
ADVICE AND ASSISTANCE.

The SI Series enclosures are fitted with M8 size threaded
inserts. Use M8 bolts only in these inserts to suspend the
enclosure. Make sure that you use forged shoulder eyebolts
with a length of at least 30mm. Insert a flat washer between
the eyebolt and the enclosure.

7.

 CAUTION: These professional loudspeaker systems are

capable of generating very high sound pressure levels. Use
care with placement and operation to avoid exposure to
excessive levels that can cause permanent hearing damage.

8. SERVICING - The user should not attempt to service this
product except that mentioned in this manual.

9. WARRANTY - In the event of malfunction, contact your
authorised Wharfedale Professional dealer or distributor for
further information. The SI Series from Wharfedale
Professional is warranted against manufacturing defects and/or
materials for a period of three years from the original date of
purchase. During that period Wharfedale Professional will at its
discretion repair or replace product provided that the product
itself is returned with notice to an authorised Wharfedale dealer.
Wharfedale Professional will not be held responsible for any
defects(or any consequential damage) resulting from
modifications made by unauthorised service agents, Acts of
God, improper use of the equipment or negligence on the part
of the user.

SI SERIES OVERVIEW:

The SI Series comprises of the SI-10, SI-12, SI-15 and SI 28 full range systems plus two subwoofers - the SI15B
and the SI-18B.

SI-10, SI-12, SI-15 and SI 28:

All the full range models are two way systems with an internal passive crossover providing high level , high
definition performance in a compact enclosure. With a nominal 70 degree coverage pattern, the system can be
arrayed for additional coverage and SPL requirements. The elliptical waveguide HF section provides consistent
coverage over its specified range for low feedback in open mic applications and improved array smoothness. M8
flypoints (20 in total) on the top, bottom and sides allow ease of installation in both horizontal and vertical
positions. The unique 5 sided multi-angle shape of the SI-10 makes it perfect for low profile ceiling mounting (or
corner installation) or as a compact floor monitor.

SI-15B, SI-18B Subwoofers:

The SI-15B and SI-18B are compact sub bass systems designed for use with the SI-15, SI-12 and SI-28 full
range loudspeakers in applications where extended low frequency output and increased system headroom are
required. These powerful systems are capable of delivering high sound pressure levels with very low distortion
over sustained periods. Superior output in extreme conditions is maintained through the use of effective
dissipation mechanisms, avoiding the loss of power compression often found in other systems.
