The simple source characteristics that coincident source driver array arrays promise are an attractive design goal but many engineering obstacles must be overcome to avoid undesirable complex behaviour. This paper outlines an innovative design approach which achieves simple source behaviour over several octaves and avoids the complex acoustical and vibrational behaviour found in traditional drivers. The high frequency section of the driver combines techniques for optimising the response introduced by Dodd [[Dodd2006]] and the radial channel phase-plug design, introduced by the authors [[Dodd2008#2]]. The midrange unit uses a cone with novel geometry allowing it to move as a rigid body to over an octave above the crossover frequency. The resulting driver and its measured behaviour is described in the light of some possible alternative approaches.
