The 2” fullrange transducers FR055WA01 (4 ohm) and FR055WA02 (8 ohm) were designed especially for high quality multimedia and lifestyle speakers, and for personal audio products, where sound reproduction without compromises is required. Will additionally work well as a midrange/treble transducer in small speaker products in combination with for instance a small subwoofer
