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, …

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. Some engineers …

The Zobel network represents a phase correcting load across the amplifier's output. It attempts to keep the combined small capacitive effects of the amplifiers printed circuit tracks, internal wiring to the speaker terminals, and the speaker cable appearing as a phase coherent resistive load.
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 …

https://www.diyaudio.com/community/threads/need-a-zobel-network-or-rc-shunt-in-tube-amplifier.267697/
A zobel network, regardless of whether you put it on primary or secondary, is the wrong way to fix HF oscillation. It's the wrong way because some small change, tube characteristic drift, hot weather, different speaker leads etc etc may cause the problem to re-appear, unless you slug the amp down so much the trebble response is affected.
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 causes deterioration in the audio band that make the sound harsh. By placing the Zobel network (R2 and C3) in between the amplifier and electrostatic speaker, this resonance is reduced. Resistance, from the electostatic panel stators, would be to the right of C1 and L1, as the stators are connected to the secondary winding of the transformer.

2. The Zobel network can help to maintain a more constant load on the amplifier. Less important than #1 but usually a good idea. 3. The Zobel network will help dampen any unplanned ringing in the crossover networks.
