There are 3 ways to connect your loudspeakers to the amplifier(s). They are single wire,
bi-wire and bi-amp.

What is Single Wiring?

Single wiring is the quickest and simplest way to connect the loudspeakers. In some
cases, it can yield better results than bi-wiring. This uses a single pair of loudspeaker
cables to connect the amplifier to the loudspeakers sending the full range signal to the
loudspeakers along the cable.

What is Bi-Wiring and Bi-Amping?

A loudspeaker's crossover varies the impedance seen by the amplifier as well as
directing the frequencies to the corresponding drivers within the loudspeaker. When
a full range audio signal is applied to the terminals of a full range loudspeaker system,
the bass driver(s) will only receive low frequency signals, the mid driver receives the
mid band frequency signals and the tweeter only gets sent high frequency signals. This
means that if separate loudspeaker cables are connected to the low and high frequency
terminals, not only have the drive units had the frequency's directed and divided for
them, but if using a bi-wire setup the two separate loudspeaker cables will now also
carry different signals due to the impedance.
The effects of bi-wiring can be subtle depending on the cable construction and design.
It could be better to go for one better engineered cable than two for bi-wiring. We
recommend experimenting with both configurations to find out which one works best in
your system.
Bi-amping adds an additional amplifier (eg. K3 Power Amplifier) to the system so that
the one amplifier drives the low frequencies - normally the power amplifier - and the
other amplifier drives the high frequencies. Bi-amping can therefore present a 'cleaner'
signal at both the low frequency and high frequency loudspeaker terminals, and
because the high and low frequencies have already been separated, each has a minimal
effect on the other - in essence the bass has less effect on the delicate treble. In order to
best take advantage of bi-amping the amplifiers should be as independent from each
other as possible. For instance, if using two stereo amplifiers you should use one stereo
amplifier for the bass and the other for the treble, minimising the impact of the bass on
the treble.
