16 ohms  
14 ohms  
10 ohms  
Nominal Impedance:  
Minimum Impedance: 7 ohms @ 6 kHz  
DC Resistance: 4.5 ohms  
Freq. Response: 500-20,000 Hz  
8 ohms  
Precise engineering, along with careful selection of materials  
and advanced driver architecture, has resulted in a driver  
that is ideally suited for the most demanding presentation of  
high quality music and communications program.  
Power Capacity: 50 Watts1, 100 Watts Cont. Prog.  
Recommended 500 Hz or higher  
Crossover :  
Incorporating Electro-Voice’s exclusive Ring Mode  
Decoupling (RMD) through all design phases has produced  
drivers with unmatched accuracy while minimizing acoustic  
resonances and time domain ringing throughout the driver  
structure.  
Nominal Efficiency: 28%  
Sound Pressure Level2 : 115 dB, HP4020 Horn  
(1 Watt @ 1 Meter) 113 dB, HP6040 Horn  
111 dB, HP9041 Horn  
The small size and weight-to-power ratio of the ND6x assures  
easy installations where weight may be a concern. The 2.15  
Tesla flux density provided by the Neodymium magnet  
exceeds that of conventional drivers at a fraction of the size.  
Throat Diameter: 1.38" (35mm)  
Voice Coil Diameter: 3" (75 mm)  
Voice Coil Wire: Pure Aluminum Ribbon  
Diaphragm Construction: 0.04 mm Pure Titanium Dome and  
Surround  
A unique, geometrically optimized 3" titanium diaphragm,  
consisting of a one-piece dome and suspension system gives  
these drivers an ideal combination of superb high-frequency  
response and resistance to fatigue.  
Electrical Connection: Screw Terminals (Accepts a pair of  
12GA Wires  
Polarity: Positive Voltage to Positive Terminal  
Produces a Positive Acoustic  
Pressure  
Integrated into the ND6x’s design is a finned aluminum  
heatsink to increase power handling and reliability.  
Flux Density: 2.15 Tesla  
Net Weight (each): 5.5 lbs (2.5 kg)  
Shipping Weight: 6.5 lbs (3.0 kg)  
The ND6x is recommended for all large horn installations  
where lower crossover points are required, such as cinema  
applications  
1 Power capacity per AES standard. Continuous pink noise, 500 - 5000 Hz with a 6 dB crest factor, 2 hours.  
2 Sound Pressure measured on axis in the far field with 1 Watt input of band-limited pink noise from 1000 - 5000 Hz  
and calculated to 1 Meter equivalent by inverse square law.
