The dual four inch diaphragm high-frequency compression drivers are capable of delivering up to 140 dB (RMS, 1W/1m) nominal SPL for long-throw applications. Fulcrum Acoustic’s proprietary TQ™ processing improves the frequency and transient responses. The DF4 is currently available in two models; the DF443 (45° x 30°) and the DF463 (60° x 30°). Enclosures are available in black or white as standard, and custom colors can also e ordered.
