OPTIMUS increases its range of quality loudspeakers for outdoor and indoor public address applications with the NEPTUNE, an acoustic hemisphere composed of five speakers, one 5" for medium and low frequencies and 4 1/2" twitters for high frequencies; its arrangement allows a sound dispersion of 360º horizontally and 180º vertically. It has a connection in low impedance of 8 ohm and 50 W of power, with a maximum SPL of 105 dB, and in high impedance by means of a 100 V in-line transformer, 30 W of RMS power and a maximum SPL of 103 dB. Added to all of the above is a good frequency response (80 ~ 20,000 Hz) and a 5 kHz crossover filter. The NEPTUNE allows the sounding of large spaces with a minimum of units, where good audio quality is also required, such as commercial halls, exhibition and fair pavilions, hotels, restaurants, gyms ... NEPTUNE acoustic hemispheres join the spheres 50W SAT360 and IP34 pendants, the ES-60W multipurpose acoustic sphere and the M8764B high-performance pendant loudspeaker to offer a complete range of solutions in high-quality, wide dispersion and high SPL PA sound points.
