The black NuQ152 2-Way 15" Full-Range Loudspeaker for Portable PA Applications from Turbosound features a 12" low-frequency driver with a low-mass voice coil for improved transient response, and an aluminum dome with 1" neodymium high-frequency compression driver mounted on a rotatable 100 x 60° (horizontal x vertical) dispersion-converging elliptical waveguide. All drivers are matched with an internal-passive crossover network in a reflex-loaded enclosure, and bi-amp mode can be enabled by means of a rear-panel switch.
