INTRODUCTION
We designed the ICS Sub 24 for maximum output and
performance for today’s digital formats. With bass
extension to 20 Hz (-6dB), and output over 105 dB at an
average listening position in a 3,000 cubic foot room,
the ICS Sub 24 meets the demanding specifications of
THX Ultra 2.
In addition to powerful and sophisticated electronics
and drivers, the ICS Sub 24 offers outstanding flexibility.
The cabinet has been designed to function in either a
horizontal or vertical orientation and front-mounted
gain control provides easy access for subwoofer level
adjustments.
