The FLEPCHER's HS15 is intended primarily as multipurpose horn speakers. This public address system is extremely suitable for diverse installations, whether indoor or outdoor, because it can respond to frequencies ranging from 380Hz to 6.5kHz. Furthermore, with an SPL of 106dB to 109dB, it is ideal for PA announcements because it can throw sound further without distorting it. HS15 is made of high-quality aluminium and has an IP 66 rating, so it can withstand even the harshest conditions. Even better, it also comes with the swivel bracket that allow users to mount the speakers on the ceiling or the walls.
