The 1½” transducers FR040WA01 (4 ohm) and FR040WA02 (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 work well as a midrange/treble transducer in small speaker products in combinbation with for instance a small subwoofer unit.
