The CB181sl is a direct-radiating, ultra-slim subwoofer
system for cinema applications. Featuring
a single 18” long excursion woofer with 4” voicecoil,
together with the large bass-reflex vents, the
CB181 delivers sustained, fundamental sub-bass output.
The Signal Integrity Sensing™ pre-wiring ensures
complete cable/connector compensation between
the CB181sl and ALC controller-amplifier. Especially
with the typical long speaker cables and the
subwoofer system’s possible low impedance, the
effect of Signal Integrity Sensing is remarkable;
Really tight and accurate reproduction for even the
lowest octaves.
The enclosure design provides for stacking, flying or
wall-mounting. The side-oriented reflex vent enables
the cabinet to be closely mounted behind the screen
without chance of screen resonance. Typical applications
for the CB181sl include cinema subwoofer or
sub-bass extension of general sound systems, used
in multiples depending of low frequency requirements.
For full system performance, we recommend using
the CB181sl in combination with an ALC amplifier/
controller. Driven by the ALC, the CB181sl not only
delivers maximum sound quality and output power,
but is also inaudibly protected against over- excursion
(SDP circuit), which is a typical challenge for
cinema subwoofer systems. |
