The ETX-35P features three high-sensitivity transducers, for high output sound which is optimized for precise coverage and low distortion. EV designed and manufactured transducers include SMX woofer technology using composite cone materials, flux stabilizing rings and thermal management. This transducer yields lower distortion, smooth response and high SPL. The high-efficiency DH3-B compression driver has a convex diaphragm driving a coherent phase device extending frequency response to 20 kHz. EV’s FIR-Drive technology utilized the latest FIR (Finite Impulse Response) filter technology to optimize transducer linearity and advanced limiter algorithms for independent peak and thermal transducer protection. The enclosure is constructed out of 18-mm, 13-ply birch plywood finished with EVCoat. ETX Powered Loudspeakers combine EV-engineered intelligent DSP, high-powered amplifiers and high-efficiency transducers to deliver that legendary EV sound and performance.
