Finite Impulse Response Filter

Adapted from EV’s concert sound systems to provide superior sound quality AND protect your investment. The latest in Finite Impulse Response (FIR) filter technology, EV’s proprietary FIR-Drive design optimizes transducer linearity for precise, balanced sonic output. Extremely steep crossover slopes provide an optimized transition from the LF to the HF transducer, eliminating all interactions. Advanced limiter algorithms offer independent peak and thermal transducer protection, even in the most demanding applications and environments. Unique in the portable sound market, all of the above add up to deliver the ultimate combination of professional audio quality and reliability.
