This system consists of a 2-way passive top and an active subwoofer. The simple interconnection of the two modules by means of a single SPEAKON® cable results in a ready set-up system, featuring high performance and an extended frequency response (from 38 Hz to 20 KHz). The maximum sound pressure (137 dB SPL) and power (1600 W RMS – 3200 W Peak) available are extremely high, providing no-compromise results when large-area coverage is required. The system is equipped with two semi horn loaded 15” woofers, featuring a 3” voce coil, four 8’’ woofers with 2’’ voice coil and a compression driver with a 1.4” throat and 3” voice coil.
The 90°x40° coverage (HxV) ensures a well-distributed sound, and the horn's adjustable angle (up to 90°) enhances horizontal coverage when using two tops side by side.
Nettuno 20 performs at extraordinarily high levels whenever especially outstanding dynamics are required. Thanks to the RD NET connectivity and the Aurora NET Software (MAC and PC) the system may be readily adapted to different applications. When it is not possible to place the speaker systems on the stage floor, the Nettuno 20 may be placed at ground level and the TOP cabinet may installed on top of the bass cabinet by means of poles or even flown. The typical application for this system is the coverage of large areas when suspended line-array systems are not suitable budget wise or by technical means.
