Clair Brothers C12-TrueFit Line Array

The Clair Brothers’ C12-TrueFit is its latest double 12-inch format midsize line array. A Clair TrueFit system design reduces energy wasted on walls and effectively extends the stereo image over a greater audience area. Fewer lateral reflections create greater focus and better intelligibility. The goal is to speed system tuning since the acoustical problem of geometric divergence shading is already solved with the TrueFit 3D acoustical solution. The C12 is offered in standard installation and portable models, featuring a new transducer technology with two noteworthy benefits: Significant weight reduction and a reduction in amplifier channel requirements. The claim is there are no technical trade-offs since these features enhance the ability for the line array to be digitally beam-steered in the vertical plane with F.I.R. processing. These models are available with a range of horizontal waveguide patterns (between 60º and 140º), while standard factory waveguides are 90ºH and 120ºH.
