The Meyer Sound X-800 high-power
subwoofer is designed to provide very
low-frequencies with ample headroom in
critical applications. The X-800 Studio and
X-800C Cinema versions from the EXP line
of products excel in environments requiring
very low distortion, extended bandwidth
and extreme low frequency transients.

The X-800C is a linear, powerful self­powered subwoofer offering excellent
phase coherence for smooth transitioning
from screen channels to low-frequency
effects (LFE), The X-800C delivers extended
low frequency output down to 20 Hz with
clear, punchy transients even at very high
levels.

The X-800C houses two Meyer Sound long
excursion, high efficiency 18-inch drivers
in an optimally tuned, vented cabinet. The
X-800C output rolls off well below 250 Hz,
avoiding any adverse comb filtering effects
that could be generated by the proximity

An integral two-channel class AB/H
amplifier with complementary MOSFET
output stages supplies a total output of
1240 Watts (2480 Watts peak), providing
the system with sufficient headroom to
accommodate lowest frequencies of the
most extreme digital soundtrack’s.

Each amplifier channel features TruPower
limiting technology to maximize loudspeaker
reliability, minimize power compression and
extend component life. An Intelligent AC™
power supply affords automatic voltage
selection, EMI filtering, soft current turn-on
and surge suppression.

A laser-trimmed differential input with
high common-mode rejection enables long
line-level signal runs using shielded, twisted­pair cable. As with all Meyer Sound self­powered products, sophisticated onboard
