Default Kelvin Connections To Speakers

Just wondered if any one heard anything about trying 4-wire Kelvin connections to the Speakers. Is that a bad idea??? Are there any advantages to trying to compensate for losses with Kelvin connections? This would put long wires in the feedback loop (which doesn't sound good). Any thoughts?

Default Just like remote-sensing in power suppies.

IMHO. the crossover inductor and voice coil resistances have way more effect than several metres of relatively thick copper wire. That said, you can try it of course, but watch out for instability because of any stray inductance and capacitance of both the power and sensing leads.

Kenwood did it about 25 years ago. IIRC, the models were the LO7M and LO5M. The reality is that there's not much to be gained in the vast majority of systems.

put it differently. If the system (amp, speakers and the rest) are so sensitive to a few meters of relatively thick copper wire, there must be some serious flaws in the system.
