Emotiva ERT/ERM/ERD Loudspeakers Proprietary Design
Emotiva ERT-8.3/ERM-6.3/ERM-6.2 Loudspeakers are designed in cooperation with loudspeaker guru
Vance Dickason, author of ‘The Loudspeaker Design Cookbook.’ All Emotiva transducers, crossover
networks and internal components are custom designed and specifically built for use in Emotiva
loudspeakers.
Transducers
• Proprietary tri-fiber composite cone - Made from two strands of a para-aramid synthetic fiber
and one strand of fiberglass, this lightweight low resonance material remains extremely rigid for
accurate sound reproduction at moderate to loud levels and flexes at the highest levels to allow the
NBR surround to absorb possible distortion. Para-aramid fibers are high strength and extremely
heat resistant, and used under various trade names for many thermal, electrical, and protective
apparel uses (including bulletproof vests).
• NBR surround for enhanced cone edge termination – Composite rubber ring reduces coloration
and distortion.
• Proprietary high performance motor structure - Computer optimized motor structure for high
sensitivity and extended linear excursion. Unique full venting design allows maximum power
handling and reduced dynamic compression.
• Integrated copper and aluminum shorting rings - To reduce distortion and 2nd and 3rd order
harmonics.
• Flat progressive rate spider - Progressive rate is compliant at low power (for efficiency), and
stiffens at high excursions for control. The harder it is pushed, the tighter it gets.
• Die cast aluminum frame - Provides rigid and precise alignment for all moving components and
increases durability. Non-ferrous frame eliminates magnetic interference, and provides enhanced
thermal dissipation and power handling.
• 25mm wide surround silk dome diaphragm tweeter - Wide surround silk dome diaphragm for
crystal clear highs without metallic harshness. Features a Ferro-fluid cooled voice coil, an
integrated heat-sink mounted on the motor structure, and an internally damped low resonance rear
chamber.
Precision Crossover
• Asymmetrical 4th order Linkwitz-Riley crossover
• Precision metal film capacitors and Low DCR air core inductors - Chosen for low distortion
and high accuracy properties in critical signal paths.
• Impedance compensation - For precise frequency response compensation and contouring.
• Phase compensation - For consistent on-axis and off-axis frequency response characteristics.
