The B475 is intended for use on the ground and can also be close stacked, while the main system is flown. This powerful loudspeaker is capable of delivering high sound pressure levels with extremely low distortion while maintaining a uniform frequency response throughout its dynamic range. This makes the speakers capable of consistent intelligibility and tonal quality at any listening level.
The B475 comprises 1 × 18” high efficiency bass units housed in a heavily braced optimally vented enclosure. Ruggedly constructed from
2. Unpacking

Cable choice consists mainly of selecting the correct cross sectional area in relation to the cable length and the load impedance. A small cross sectional area would increase the cables series resistance, inducing power loss and response variations (damping factor).
Connectors should be wired with a minimum of 2.5 sq. mm (12 gauge) cable. This will be perfectly satisfactory under normal conditions. In the case of very long cable runs the wire size should exceed this, refer to the following table for guidance: -
