1. INTRODUCTION
2. KEY FEATURES 3. APPLICATIONS
The KU210 is an ultra thin, high performance passive subwoofer designed to be the perfect companion
to any of the K-array Installed Sound Series. A combination of extended frequency response with
prodigious output and a virtually invisible profile make the KU210 an ideal fit even the most ambitious
projects.
The Subwoofer is comprised of a 10” neodymium transducer, combined with a 10” passive transducers,
instead of a reflex, which ensures that the device remains completely sealed. The unit is engineered for
maximum linear excursion and minimum residual noise. Its neodymium transducer has a double voice
coil to allow for selectable impedence settings allowing you to combine up to 4 KU210s powered by
just one channel of the KA84 amplifier.
KU210 is made entirely of steel, making it extremely resistant, even when deployed outside in tough
weather conditions. This makes it ideal for marine environments where ordinary bass speakers would
corrode. It cannot be penetrated by foreign objects such as dust, sand or water, which over time can
ruin a speaker.
All KU210 components are designed by the K-array R&D department and custom made under the K-array quality control system.

5. SAFETY INFORMATION
Warning. Failure to follow these safety instructions could result in injury or damage to the device or other property.
IMPORTANT SAFETY INSTRUCTIONS
• Read these instructions.
• Keep this instructions.
• Heed all warnings.
• Follow all instructions and keep all warnings.
• Only use attachments/accessories specified by the manufacturer.
• Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with
the apparatus.
• When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
• Avoiding hearing damage. Professional loudspeakers are capable of producing extremely high sound
levels and should be used carefully. Never stand close to loudspeakers driven at high volume. Set the volume to a safe level. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. Hearing loss get worse every time you’re exposed to a sound level of 90 dB or over for an extended period of time. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected.
• Choking Hazards. This device contains small parts, which may present a choking hazard to small children. Keep the device and its accessories away from small children.
• Do not make repairs yourself. Never attempt to disassemble, repair or modify the system yourself.
Disassembling the unit may cause damage that is not covered under the warranty. The device contains no user-serviceable parts. Repairs should only be performed by factory trained service personnel.
• Sound distortion. Do not operate speakers for an extended period of time with sound distortion. This is an indication of malfunction, which in turn can generate heat and result in a fire.
• Carrying, handling and installing the device. The device contains sensitive components. Do not drop,
disassemble, open, crush, bend, deform, puncture, shred, incinerate, paint, or insert foreign objects into it. If your device has been dropped or damaged unplug the power cable immediately.
• Set up. Set up your device on a stable retaining horizontal surface. If combined or mechanically
connected with other products, always verify the stability of the resulted system. Install the unit only in a location that can structurally support the weight of the unit, far away from people who can interfere with the stability of the system. Assure that the wind does not interfere with the system’s stability, taking extra securities like chains, weights, ropes or any other certified anchoring systems. Doing otherwise may result in the unit falling down, causing personal injury or property damage or even death. The system should only be suspended by qualified personnel following safe rigging practices. Secure fixings to the building structure are vital. To clarify any doubt you may have, seek help from architects, structural engineers or other specialists.

8. wIRINg
The KU210 is comprised of a neodymium transducer, combined with a 10” passive transducer. The neodymium transducer features a double voice-coil (8Ω + 8Ω). T The two voice coils can be wired in parallel (resulting in a 4Ω total impedance) or in serial (resulting in a 16Ω total impedance). To do this, we provide a 4-pin female Phoenix connector where users can make the wiring; then the female Phoenix connector is plugged into the male Phoenix connector situated at the back of the speaker. We provide also a “serial cable” that can be used to connect the two central pins of the phoenix connector in the 16Ω configuration.
NOTE. The K-array KA84 amplifier can drive up to four KU210s@16Ω per channel. The K-array KA24 amplifier can drive one KU210@4Ω per channel.

8.1 K-2SPK ACCESSORY
This accessory is used to connect a Speakon cable to a KU210. It features two Speakon connectors wired in parallel giving you the possibility to wire two or more KU210s in parallel using only Speakon cables. The two wires situated at the back of the K-2SPK carry the signal from the 1+ contact (red wire) and 1- contact (black wire) of the Speakon connector. Wire them to the phoenix connector as shown in the previous section. Use the four screws and the four hexagonal spacers included to mount the K-2SPK on the KU210.
