A system for producing sound waves in a medium, the system comprising: at least two woofer free-flooded ring transducers 100 centred about a first axis (columnar woofer array 802, figure 8), the woofer free-flooded ring transducers 100 being substantially cylindrical and having an axial gap of height g there between such that they form a woofer column (802); and at least one cylindrical body 500a,500b centred about the first axis nested in the woofer column, such that the cylindrical body is aligned with the axial gap. The cylindrical body (500) may be a tweeter free-flooded ring transducer. This combination of ring transducers provides for improved wideband performance in a free flooded ring array. This system may be used as a sonar system for locating submarines. |
