Additionally, in applications where an amplifier drives multiple speakers, and a crossover network is used, the Zobel network eases the design of the crossover network by keeping the load impedance resistive. With the advent of higher power (>100W) integrated circuit (IC) audio amplifiers, the selection of component values for this network, if not done correctly, …

Zobel network is at the output of all solid state amplifiers. Solid state amplifiers are only stable with a perfect Resistive load that has no capacitive reactance. Anything that causes a slight high frequency rotation of phase at the amplifier output is fed back through the negative feedback path to the -inverting input.

For DIY Audio Amplifier Builder, the Boucherot Cell or commonly known as Zobel Network is composed of Series Resistor-Capacitor (RC network), Capacitor CA and Resistor RA at the back-end or at the output stage of a discrete power amplifier design, as in the figure below, it is often misunderstood its function and simply accept it as copy and paste.
Voice Coil Lab Notes: Improved Zobel Network - audioXpress
https://audioxpress.com/article/voice-coil-lab-notes-improved-zobel-network
An improved compensation network can be realized by using the analogous circuit “dual” of the L2/R2 model. This represents a dramatic improvement to the basic two-component Zobel network and compensates for the non-ideal semi-inductive behavior of the loudspeaker driver across the entire frequency band. Passive crossover filter networks for multi-way …

Zobel networks are as old as amplifiers, and they are still used. The data sheets for common audio amplifier IC's show a zobel network across the output - eg LM3886 datasheet page 6 which I have to hand right now. Same with TDA2030A application notes. …

Little Things: Using a Zobel Network to Reduce Harshness ...
https://hometheaterhifi.com/blogs/little-things-using-a-zobel-network-to-reduce-harshness-with-electrostatic-speakers/
This transformer raises the amplifier voltage to a higher voltage that goes to the stators. This problem can be alleviated by the use of a Zobel network. A Zobel network consists of a capacitor, resistor, and sometimes, an inductor. Some of my reference speakers are electrostatic, and I did notice that the sound had a harsh character to it.
Speaker Zobel / Impedance Equalization Network Circuit ...
https://diyaudioprojects.com/Technical/Speaker-Zobel/
Speaker Zobel / Impedance Equalization Network Circuit Calculator. An Impedance Equalization Circuit, also know as a Zobel circuit, can be used to counteract the rising impedance of a voice coil caused by inductive reactance. The cause of this impedance rise is due to the speaker's voice coil inductance (L e). A schematic of a impedance equalization circuit (zobel) …
