1. Introduction Thank you for purchasing Tannoy B475. The Tannoy B475 is an 18” direct radiating bass loudspeaker system, designed for high definition sound reinforcement at low and ultra-low frequencies. It will extend the power bandwidth of Tannoy i/T range mid/high sound reinforcement systems to below 30Hz, making it ideal for effects in club, theatre and concert sound applications, with ultra-low frequency enhancement and increased system headroom.

6. Crossovers For optimal performance the B475 has been designed to operate with Tannoy Install or Transportable series, e.g. i12/T12, i15 and T300, where overall system control is achieved by utilising the TDX2 system controller. The TDX2 has been factory preset to provide the recommended cross-over points, delays and overall system balance.
9. Positioning When a bass loudspeaker is used in an environment with boundary surfaces, its placement affects its frequency response. When such effects are properly understood, they can be used to great effect in producing the desired sound quality without the aid of additional amplification. Consider Figure 9a in the diagram below, here we see a loudspeaker in free field or anechoic conditions.
