Loudspeaker Cables
Specialist loudspeaker cables will oer a higher standard of reproduction than
general purpose ‘bell’ or ‘zip’ wire. Use cable with generous amounts of copper.
Thin cables reduce the bass and restrict the dynamic range.
Speaker cable has a stripe or tracer along one core. By convention this is
connected to the positive terminals. The cables connecting the amplier to the
front loudspeakers should ideally be the same length. Never join cables - use
complete lengths.
Terminals and Connectors
The Concept 20s and 40s are bi-wireable. A bi-wireable crossover has four
terminals. The upper pair of terminals connect to the treble (HF) speaker and the
lower pair to the bass (LF) speaker/s. As supplied the crossovers are tted with
removable links to connect the terminal pairs. This permits you to connect the
loudspeaker conventionally using one pair of cables or in bi-wired mode with
two pairs.

Preparing Cables
Split the cable to a depth of about 40mm. Bare
the wire to a depth of 10mm and twist the
ends to gather any stray wires. Crop the cable
leaving 7mm of bare wire exposed.
Connecting a Terminal
Unscrew the terminal anticlockwise to expose
the mounting hole in the base of the terminal
column.
Insert the bare end of the cable into the hole.
Re-tighten the terminal fully hand tight. Make
sure there are no stray wires which could touch
adjacent terminals.
In the EU it is against safety regulations to use
4mm loudspeaker plugs.
