The SP series are high-efficiency sound projectors designed to provide good speech intelligibility and background music in a wide variety of applications. Designed for indoor use and perfectly suited to be used in large 70/100V broadcast systems such as train stations or airports. The ASP20 is a 20 Watt spherical loudspeaker, fitted with an 8" driver and a 70/100V line transformer with different power tappings for 20 Watt, 10 Watt and 5 Watt. Its wide, smooth frequency response and high efficiency ensure high fidelity music and speech reproduction with a 360° horizontal coverage. This makes it perfect for big, open areas like factory halls or large retail spaces.
