  • Page 5: Introduction

    1. Introduction Thank you for purchasing Tannoy B225. The Tannoy B225 is a 15” direct radiating bass loudspeaker system. For installations that require extended bass response from an ultra-compact cabinet, with flying and wall-bracket mount capabilities, the B225 makes the ideal companion to Tannoys' i/T series of sound reinforcement loudspeakers.

    6. Crossovers For optimal performance the B225 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.

  • Page 8: Positioning

    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.
