CHAPTER 5 – AMPLIFIER RECOMMENDATIONS
No single type of amplifier is
specified for use with the Project
K2 S5800 system. The speakers are
highly efficient and will operate
adequately with an amplifier or
receiver of 70–100 watts.
However, the transient response
and audio definition of a high-end
system such as
Project K2 S5800
will pick up all inefficiencies and
distortion in an amplifier system.
For full-range operation, the
Project K2 S5800 system can be
used with an amplifier/receiver of
as little as 30 watts. Amplifiers/
receivers of 100–300 watts
will ensure optimum system
performance.
There is no effective limit to the
power handling capabilities of the
Project K2 S5800 loudspeakers
when driven by consumer audio
amplifiers. No damage will occur
when used with high-powered
components. Source impedance is
an important criterion in selecting
an appropriate unit; the selected
amplifier(s) should have a very
high current capacity and must
be capable of driving a low
impedance load.
For bi-wiring or bi-amplification
applications, four identical ampli-
fiers or two dual-channel units may
be used, although specialized low-
frequency and high-frequency
amplifiers offer clear advantages.
(If four amplifier channels are used,
the high-frequency amplifier may
be up to 6dB less powerful than
the low-frequency amplifier. Due
to the
power versus frequency
distribution of the music, the low-
frequency section requires approxi-
mately four times the power of the
high-frequency section.)
Project K2 S5800 specialist dealers
can recommend amplification to
best suit individual needs. In all
cases, the left and right amplifiers
for each section must be identical.
Make sure that the input sensitivity
of the two amplifiers is equal or
that
input level controls are provided to
maintain the proper low to mid/high
balance. If two identical stereo
amplifiers are chosen, each amplifier
may be located near a
loudspeaker
and drive low-frequency
and high-
frequency sections through short
wire runs.
