General Features for Two-Way Enclosures
• High-grade neodymium-magnet speaker components are matched with an
internal passive crossover to ensure a seamless transition between the high frequency and low frequency drivers.
• 12” and 15” models are switchable active / passive via a rear panel toggle switch
to enable fully bi-amplified operation.
• The 1” high frequency compression driver used in the NuQ-8 and NuQ-10 is a
proprietary design based on the award-winning Aspect® series HF driver.
• Cabinets are constructed from high quality pre-formed birch plywood; rebated,
glued and screwed together for maximum strength and rigidity. This construction method entirely eliminates four cabinet joints and reduces overall weight.
• The symmetrical quasi-trapezoidal cabinet shape with 45° side angle is designed
to enable reversible low profile wedge monitoring applications
• Multiple rigging points enable a wide variety of installation methods: on speaker
stands and poles; with Turbosound yokes and swivel brackets; with OmniMount™ hardware and specifically created Turbosound wall brackets. The enclosures are also fitted with internal M10 threaded rigging points on the top, sides, bottom and rear, that allow single cabinets to be suspended and angled in fixed installations.
• The rigging points on the bottom of the cabinets enable them to be hung upside
down in order to position the HF driver closer to the audience.
• NuQ Series two-way enclosures are designed to give good pattern control down
to crossover frequency, and are fully supported with EASE polar data (available to download from the Turbosound website at www.turbosound.com). This enables accurate and predictable results when specifying sound systems in a given venue.

System Requirements
Passive loudspeakers and switchable loudspeakers used in passive mode
NuQ series passive loudspeaker enclosures require only one amplifier channel for correct operation, the frequency splitting between the low frequency driver and the high frequency driver being accomplished by the internal passive crossover network built into each enclosure.
If subwoofer enclosures are used as part of a bi-amplified system in conjunction with NuQ series 2-way enclosures to extend low frequency response, additional amplifier channels and external electronic crossovers will be required. The Turbosound LMS-D6 and LMS-4 digital loudspeaker management systems are recommended for this purpose, as well as other professional quality digital controllers.
Switchable active/passive loudspeaker enclosures when used in bi-amped mode require the use of one amplifier channel per frequency band for correct operation. Frequency splitting between the low frequency driver and the high frequency driver is accomplished by a Turbosound LMS-D2X digital loudspeaker management system.
user manual
Dedicated subwoofer enclosures require an additional amplifier channel when used as part of an extended frequency system. Frequency splitting between it and a NuQ series mid-high enclosure is accomplished by an external crossover. Turbosound LMS series digital loudspeaker management systems are recommended for this purpose.

NuQ series
Amplifier Considerations
Turbosound NuQ series loudspeaker enclosures should be driven by high quality power amplifiers designed for true professional use. Such amplifiers will have balanced inputs, DC and RF fault protection, and well designed cooling systems for reliability.
The ‘program’ power, listed in the loudspeaker’s technical specification, is the best guide to the size of amplifier required for general purpose applications. The amplifier should be capable of delivering long term broadband power equal to the loudspeaker’s program power rating at the loudspeaker’s stated nominal impedance. This approach allows sufficient headroom to generate good dynamic range.
RECOMMENDED AMPLIFIER POWER RATINGS:
The amplifier's rated continuous power output (20Hz – 20kHz, per channel)
should be equal to the program power handling of the loudspeaker at its
nominal impedance.
It should be understood that overdriving an insufficiently powered amplifier is more likely to cause loudspeaker damage – the total energy in a heavily clipped signal is far higher than in an unclipped signal – than operating a more powerful amplifier within its ratings. In general, the more powerful the amplifier the better it will sound, provided that it is not also driven into sustained clipping.
All the equipment in the system before the system controller should be set up for 0dBV (775mV) maximum output. One controller can be used to feed several amplifiers as long as all the amplifiers are the same (or have the same gain ratings). More than one controller may be required if the amplifiers are of different gain or type. Please contact your dealer if you require help in this area.
Turbosound recommends the T-series amplifiers for use with the NuQ series system. For further information on T-series power amplifiers please visit the product showroom section of our website at www.turbosound.com

NuQ series
Self-powered Loudspeakers
The Class D amplifier modules fitted to the NuQ-8DP and NuQ-10DP self-powered loudspeakers comprise one amplifier channel rated at 500 watts continuous, powering both low frequency and high frequency drivers through a passive crossover network.
The Class D amplifier modules fitted to the NuQ-12DP and NuQ-15DP self-powered loudspeakers comprise two amplifier channels rated at 800 watts continuous: one channel to power the low frequency driver (LF) plus another channel to power the high frequency (HF) driver; plus an active crossover to split the signal and feed it to the appropriate amplifier and driver section. Additional features such as limiting, digital time alignment and driver EQ are carried out in the on-board DSP.
The Class D amplifier modules fitted to the B15DP and B18DP self-powered subwoofers use the two-channel amplifier bridged to provide 1600 watts continuous.
Self-powered NuQ series products do not require the use of external amplifiers or crossover/limiters.
user manual
Additional units may be daisy-chained together simply by linking the signal connections through the input / link XLR connectors. In this way exact coverage of an event or permanent installation may be achieved using a number of digitally powered loudspeakers. It is however necessary to route individual power cords to each enclosure as it is not possible to daisy-chain AC connections through the power connectors.
