Important Warnings & Safety Instructions
- READ ALL INSTRUCTIONS carefully and become familiar with the features and functions of these products before operating them.
- RETAIN THESE INSTRUCTIONS for future reference.
- COMPLY WITH ALL WARNINGS: All warnings and instructions for this product should be adhered to.
- USE WITH AMPLIFIERS: To avoid damage to drivers and other equipment, establish and follow a routine for powering up and powering down a sound system. Connect all system components, 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. Ensure amplifier volumes are set to their minimum settings and power up any system amplifiers LAST. Allow all system components to stabilize for several seconds before introducing any source signals or making level setting adjustments. Similarly, when shutting systems down, turn all amplifiers off first, before powering down any other system components.
- CABLES: Do not use shielded or microphone cables for connection between amplifiers and speakers. Use only approved speaker cables with proper connectors.
- 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.
- SERVICE: There are no user serviceable parts inside this product. Users should not attempt to service this product. Warranty nullification could result if this is attempted.
- 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
The Delta X Series 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 is not the only improvement the engineering team has made. Internally, Delta X also features 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 amplifiers 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 fixed 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 qualified 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. Failure 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 reflections. Please ensure that the correct socket is used for each speaker.
Wiring Diagrams
The following sections detail wiring configurations for various Delta X Series models:
- Delta X10/X12/X12M/X15/X15M/X215 Bi-Amp Wiring: Illustrates connections from LF and HF amplifiers to the speaker's Speakon connector, with an external active crossover routing signals from a mixer. The switch on the speaker is set to 'BI-AMP MODE'.

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 considering suspending any loudspeakers.
Each primary load-bearing suspension point shall be rated for the total load. A minimum 5:1 Design Factor or Local Standard should be observed, whichever is greater.
