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.
