The sub bass loudspeaker systems shall incorporate 2x 18-in
LF transducer mounted in a vented enclosure tuned for opti­mum low frequency response.

System frequency response shall vary no more than ±3 dB
from 31 Hz to 200 Hz measured on axis usin g appropri ate sig­nal processing. The loudspeaker shall produce a Sound
Pressure Level (SPL) of 98 dB SPL on axis at 1 meter with a
power input of 1 Watt, and shall be capable of producing a
peak output of 135 SPL on axis at 1 meter. The loudspeaker
shall handle 1600 Watts of amplifier power (continuous) and
shall have a nominal impedance of 8 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of multi-ply, void-free cross-grain-lami­nated Baltic birch plywood and shall employ extensive inter­nal bracing. It shall be finished in black catalyzed
polyurethane. Input connectors shall be dual Neutrik NL4
Speakon. The front of the loudspeaker shall be covered with
a vinyl coated perforated steel grille.

The sub bass loudspeaker shall be the EAW model LA128z.
