CHAPTER 4
Selecting Cable
Speaker wire and interconnecting cables are important components in any
audio system. With a system such as the K2 S9900, they assume a new level
of importance.
The K2 S9900 loudspeakers are internally wired with high-quality oxygen-free
copper cables. The same care that was given to the selection of the internal
system wiring should be afforded to the selection and application of the cables
that will connect the K2 S9900 loudspeakers to other system components.
It is advisable to use high-quality wire and to select the highest grade wire
available from the manufacturer. Many manufacturers produce audiophile cables
which are worth considering for the K2 S9900. As with all electronics and
associated components, however, every manufacturer offers products of varying
quality to suit a range of budgets and applications. Using an audiophile-quality
speaker wire of not less than 16-gauge for connections of up to 15 feet
(5 meters) is recommended as a minimum requirement. K2 S9900 specialist
dealers have the experience and knowledge to recommend suitable speaker
wire to best complement a particular system. For maximum signal purity, it
is advisable to place the amplifier(s) as close as possible to the loudspeakers,
even if this means that a longer distance will be needed between the amplifier(s)
and preamplifier.
The left and right speaker/amplifier connections should be the same length.
If the distance between one speaker and the amplifier(s) is greater than
the other speaker and amplifier(s), use the longer length of wire for both
connections. For bi-wire connections, the same type of wires may be used
for both low-frequency and high-frequency sections to reduce wire effects
(resistance, inductance, etc.) and to avoid intermodulation of low and high
frequencies in the wires. Specialized wires for low-frequency and high-
frequency sections may yield excellent results. Whatever wires are used,
be sure that the low-frequency wires are as short as possible, and the left
and right wires for each section are the same length.
To ensure a secure connection, Y- or U-type plugs are recommended.
