method requires one amplifier
and two sets of speaker wires.
By removing the shorting

made to the individual network
sections using four conductors,

These models feature four
rubber feet that enable them
to be placed on a smooth-
surfaced floor, such as tile or
hardwood. Four metal spikes
are supplied for use when the
speaker is to be placed on a
carpeted surface, to decouple
the speaker from the floor and
prevent unwanted damping.
