No,  I was talking about "quarter inch phone plugs",  of the type commonly 
used with audio cables...

I've only ever seen twist-lock connectors used for speaker connections,  and 
those are not normally shielded.  The common "Cannon" or "XLR" type of plug 
doesn't get twisted,  it just goes straight in and locks.

Speaker wire can be any number of different gauges,  depending on what power 
level is being handled and how long a run there is.

Yeah,  it sure is,  so if we want to pursue this we maybe oughta take it up 
in ELECTRONICS or somewhere else...
