15-inch two-way full-range passive loudspeaker system is new standard of no compromise audio performance and versatility in simple to use, compact package. At its heart are transducers. First is the DVX3150 high performance low frequency transducer. EV used advanced computer aided design techniques to create forced air, directional voice coil cooling for high power and efficiency. Finite element analysis was used to optimize the suspension and magnetic structure for long, linear travel to provide low distortion and greater LF extension. These features and details, such as forged magnetic components and special materials, provide reliability with 500W power rating in lightweight transducer.
