Tender Specification: Scale-1 Compact passive 2-way speaker system with extended lowend and a scalable enclosure. The passive 2-way speaker is designed as a point source in a slim line source speaker enclosure (width: 133 mm). It is equipped with a 4" long excursion driver, a 0.75" dome tweeter and a passive membrane working as a sub extension. No additional subwoofer is needed. The frequency range is 44 Hz - 20 kHz. Its nominal power rating is 50 W (100 W program, 200 W peak) at a nominal impedance of 4 ohms. It reaches a maximum sound pressure level of 104 dB. The nominal dispersion is 140° x 90°. The use of multiple systems enables scalability from small to larger applications. The speaker system has a light aluminum enclosure with rounded sides. If required, the enclosure length can be made to measure and coated in special colors from the RAL Classic, NCS and Pantone catalogs or with photo-realistic surfaces. The ball impact resistant front grille is also painted in the same color as the enclosure. The speaker system has standard dimensions of 133 x 355 x 128 mm and a weight of 2.8 kg. A continuous T-slot on the rear of the enclosure allows maximum flexibility in installation, whether horizontal or vertical. For operation, the corresponding system amplifier with the correct speaker preset is required.
