Cómo Funciona
A speaker crossover network is an essential circuit in audio systems that divides audio signals between different speaker drivers (woofers, tweeters) to ensure optimal frequency reproduction. The crossover frequency determines where low and high-frequency signals are redirected, protecting speakers and maintaining sound quality by preventing drivers from reproducing frequencies they're not designed to handle.
Ejemplo Resuelto
Problem: Design a 1st-order crossover at 1 kHz for an 8-ohm speaker system Solution: 1. Calculate crossover frequency: fc = 1000 Hz 2. Calculate inductor: L = Z/ωc = 8 / (2π * 1000) = 1.27 mH 3. Calculate capacitor: C = 1/(Z * ωc) = 1 / (8 * 2π * 1000) = 20 µF 4. Verify components will effectively split signal at 1 kHz
