I have just bought some 'speaker zapperators from Russ Andrews.
These are, apparently, Zobel networks.
They have changed the sound of my 'speakers. This is the technical section, so it's not appropriate to say whether they've made it better, worse or just different.
What is a Zobel network, what does it do and how does it do it, please?
I've looked on Wikipedia and got flummoxed by the article. The photo of the old BBC studio with it's variable Zobel network is great, though!
So, an easy to understand reply, suitable for a non electronicy person would be appreciated.
