Doesnt resistance mean same as impedance??


Very confusing.  Low vs high impedance.  Most amps can handle any level.

good preamps have lower impedance output. 
 

what does it all mean?

 

easier if resistance term is used, since i am too unsmart to follow impedance

perhaps @carlsbad ’s understanding is not incomplete, but i do agree with you that his description was... of course he was trying to keep it simple for our o-p

the reactivity of speaker loads in real world use playing music at practical volumes (not test tones, etc etc) is at the heart of why amplifier to speaker matching (and synergy) is such an important concept, and so central to building a well performing system

Genius is explaining stuff so its understood by avg joes like me, in my view.

 

“conductors reacting to current (voltage) changes” - to me this may go to heart of understanding issue.

so it seems connectors used to bridge components, and a means to control and/or react to voltage changes within a component is vital.

what spec deals with this issue? Or not.

Google it, get it right and avoid all this, unless northman is right ...

From a speaker perspective the spec is a rather complex chart of impedence vs frequency including the phase angle component, often called load. There is no single amplifier spec of an amplifiers ability to “ deal “ with the complex load w real music, so we end up using square waves ( made by using sine waves of many frequencies ), a simulated speaker load and then looking at power output and distortion at various loads. For a SS amp the accepted benchmark is ability to double power in watts as impedence is cut in half. This is also imperfect. Great amp designers are measure and listen people.
