augmentation. There is a separate
.1 channel input so that the system
may be switched between stereo and
at the upper frequency limits.
Neodymium magnets generate the
intense field required for extended
frequency response. The patented
Constant Q waveguide maintains a
uniform dispersion pattern at all
frequencies, with no lobing apparent
even when measured at 1/12 octave
resolution. The result is stable
imaging with a wide "sweet spot."
Both transducers are driven by
Class AB/H complementary power
MOSFET amplifiers, with 620W
available for the HF section and
1200W for the LF section. Class
AB/H topology strikes an ideal
balance between ample power
reserves and sonic purity, with all
devices operating as Class A below
40W nominal output. The control
electronics package, refined from
experience gained with the HD-1,
includes an active crossover with
pole-zero response correction filters
and loudspeaker protection that
remains completely out of circuit
except when triggered by
linearity of the overall system.
(Unlike conventional monitors, the
X-10 does not simply move into
a more non-linear region when
presented with peak levels beyond
specified capabilities. It remains
linear at all times, under all

inadvertent, potentially damaging
overloads.
For applications requiring very
high monitoring levels coupled with
extreme LF transients, the X-800
self-powered subwoofer adds extra
headroom to the X-10 system.
Because the X-10 is a full-range
system, the X-800 is not intended to
extend frequency response; rather it
extends headroom by at least 5dB
while still maintaining the absolute
conditions.) Also, because the
X-800's dual 18-inch drivers are
not tightly controlled by PSAC, they
retain the subtle timbral cues of
traditional subwoofers–a subjective
characteristic that many listeners
find familiar and pleasing. The
X-800 output is contained well
below 250Hz, so no adverse comb
filtering effects are generated by the
All components of the X-10

transducers, are manufactured by
