Visaton's K50 SQ 2" full-range speaker features a unique weather and UV-resistant design. When used in a sealed enclosure, the front of this speaker conforms to the IP65/67 water resistance rating (meaning it can withstand direct moisture). The K50's specialty is vocal reproduction with great output in the 500 to 5,000 Hz range, making this the perfect driver for use in small projects designed for use outdoors.
