The ZX3-90PI-B from Bosch is a 12-inch two-way, 90° x 50°, 600W, passive loudspeaker, black. The Zx3 is the new standard of no compromise audio performance and versatility in a simple to use, compact package. At its heart are the transducers. First is the DVX3121 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 a 500W power rating in a lightweight transducer. Next is the ND2, a 2-inch voice coil compression driver based on neodymium motor structure to allow for maximum output while reducing size and weight to a minimum. Its precision phasing plug and titanium diaphragm provide better HF performance, while the integral heatsink provides cooling for high power output.
