Analog: Active Crossover Circuit for Two-Way Loudspeakers
Description
This TI Verified Design implements an analog active crossover solution for two-way loudspeakers which is suitable for recording studios or home high-fidelity systems. The woofer signal pathway includes a low-pass shelving circuit for baffle step compensation and a 4th-order Linkwitz-Riley low-pass filter. The tweeter signal pathway includes a 4th-order Linkwitz-Riley high-pass filter: 3rd-order all-pass filter for time alignment: and output attenuation and buffering.
