Fulcrum Acoustic has released the DF4 Dual High-Frequency Horn, a spot fill loudspeaker intended to provide supplemental high-frequency coverage for areas shaded by obstructions in such applications as sporting arenas and stadiums, houses of worship, theaters, restaurants, transportation facilities and theme parks.
The enclosure’s dual 4-inch diaphragm high-frequency compression drivers are capable of delivering very high output for long-throw applications. Fulcrum Acoustic’s proprietary TQ processing improves the sonic character, guaranteeing exceptional clarity and precise transient response even at very high SPL, according to the company.
The high output DF4 spot fill loudspeaker is currently available in two models – the DF443 (45° x 30°) and DF463 (60° x 30°).
