AB  - Tweeters according to the Air Motion Transformer principle (AMT) have convinced in Studio Monitoring and High Fidelity applications particularly due to their transient behaviour and low distortion and therefore are becoming increasingly popular. The idea to exploit these advantages in live sound can be tempting. However, manufacturers of sound reinforcement systems have been reserved to Air-Motion-Transformers due to the alleged lack of maximum level. Nevertheless, the AMT is in principle perfect for a line array because of its natural properties as a line source. In this investigation, a compact and efficient line array using a newly developed Air Motion Transformer has been developed. The 2 ½ way line array reaches maximum levels at least equal to current systems. Measurements of maximum level capabilities and moderate-level distortion were carried out. We also report on subjective impressions in practical setups. It can be concluded that the desired precision sound of AMT tweeters can be transferred into mid-scale to large-scale live sound applications.
