You need to ensure that cables to similar speakers are exactly the same
length - a millimeter out could completely ruin the phase relationship
and affect hearing. Also if marked with any directional indications -
those indications followed to the letter, or the electrons will cause
localised heating in the amplifier which may be a potential fire risk if
left unattended.
