IMPORTANT WARNINGS & SAFETY INSTRUCTIONS
1. READ ALL INSTRUCTIONS – carefully and become familiar with the features
and functions of these products before operating them.
2. RETAIN THESE INSTRUCTIONS – for future reference.
3.
COMPLY WITH ALL WARNINGS – All warnings and instructions for this
product should be adhered to.
4. USE WITH AMPLIFIERS – In order to avoid damage to drivers and other
equipment, it is advisable to establish and follow a routine for powering up and
powering down a sound system. With all system components connected, turn
on source equipment (mixers, signal processors, record and playback units,
etc.) BEFORE powering up amplifiers. Transient voltages from powering up
source equipment can damage speakers if amplifiers are already turned on.
Make sure that amplier volumes are set to their minimum settings and power
up any system ampliers LAST. It is recommended that all system components
be allowed to stabilize for several seconds before any source signals are
introduced or level setting adjustments are made. Similarly, when shutting
systems down, turn all amplifiers off first, before powering down any other
system components.
5. CABLES – Do not use shielded or microphone cables for connection between
amplifiers and speakers. Use only approved speaker cables with proper
connectors.
6. 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 volume levels. Permanent hearing
damage can result when operated to extreme levels.
7. SERVICE – There are no user serviceable parts inside this product. Users
should not attempt to service this product. Warranty nullication could result if
this is attempted.
8. RIGGING - SUSPENDING - MOUNTING - Rigging suspending or mounting of
speaker systems can expose members of the public to serious health risks and
even death.
UNDER NO CIRCUMSTANCES ATTEMPT TO RIG, SUSPEND OR
OTHERWISE MOUNT THESE SPEAKERS 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.

INTRODUCTION
Delta X builds on the global success of the Wharfedale Pro Delta series.
Constructed from 15 mm plywood and covered in the highest quality Rhino Rock
paint, the Delta X models are instantly recognizable by their engraved iconic
Wharfedale Pro ‘boomerang’ logo on their cabinets. The fresh cosmetic design
however is not the only improvement the engineering team have made.
Internally Delta X also has a new crossover design and construction. Using new
component positioning and bracing, the sensitive crossover electronics have
been re-engineered to improve long term performance and reliability - even at the
highest of volumes.
With rear panel switching, Delta X can operate in either Bi-Amp or Full range
modes. This routing flexibility allows for Delta X systems to be refined using
multiple ampliers and external crossovers.
Custom Wharfedale Pro transducers have also been selected. High output,
low physical distortion cast frame woofers deliver unparalleled low frequency
response. With the exception of the Delta X10, 2” titanium compression drivers
are coupled to 90°x45°elliptical waveguides for impressive output level and
smooth HF dispersion.
With a full lineup of 9 models, ranging from the 300 w RMS Delta X10 to the
1600 w RMS Dual Chamber 2 x 18” Delta X218 subwoofer, Delta X models are
perfect for xed installation and touring applications.

INSTALLATION
• Before attempting to install a Delta X Series loudspeaker system please refer
to the important warnings and safety instructions. Only qualied personnel should
install a loudspeaker system.
Improper installation of a loudspeaker system can cause serious
harm and even death if correct procedure is not followed. Anyone
attempting installation assumes all liability arising from such use.
• Bi-amp switching - ensure that the internal passive network selector is in the
correct position. When using an external active network select the bi-amp setting.
Failiure to do this can result in damage to the drivers of your Delta X Series
loudspeakers.
• Models with dual angle pole mount sockets (Delta X10, Delta X12 and Delta
X15) have an angled socket that angles the cabinet down by 10°. This allows
more sound to be aimed directly at the audience and less at the ceiling, reducing
early reections. Please ensure that the correct socket is used for each speaker.

RIGGING/SUSPENDING
Using Shoulder Eyebolts
Always apply the load to the bolt along the plane of the eye. For long term
installation use a thread-locking compound. Do not attempt to bend or otherwise
deform any rigging hardware.
Please refer to the important safety warnings before you consider
suspending any loudspeakers.
(A minimum 5:1 Design Factor or Local Standard should
be observed, whichever is greater)
Each primary load bearing suspension point shall be rated for the total load.
Forged shoulder eyebolt
(User supplied, overhead
suspension rated and certied)
Secondary Suspension Point
Forged shoulder eyebolt
Working load limits:No more than four (4) high (vertical)
The four (4) high vertical specication represents a static ratio of 7:1
