The Hitune Bass HM-21SU (KT Ref: KTI14004005HM21) is engineered for high-clarity voice projection across outdoor industrial sites and commercial facilities. Built with an all-ABS plastic body for rugged handheld or shoulder-slung operation, the acoustic horn flare measures 230 mm in diameter with an overall longitudinal length of 350 mm.
Its audio amplification circuit is rated at 20W RMS with a maximum power output handling of 25W (labeled up to 50W max peak in high-output bursts). This produces an effective intelligible voice broadcast range of 0.5 km (500 meters) under ambient noise conditions, extending up to 1.0 km to 1.2 km in quiet, unobstructed open areas. The unit weighs 1.46 kg net and approximately 2.0 kg ready for field deployment.
