Fulcrum Acoustic Releases DF4 Dual High-Frequency Horn Loudspeaker

Fulcrum Acoustic continues to create new innovative loudspeakers at an impressive pace. Now, the Massachusetts-based manufacturers has released the DF4 Dual High-Frequency Horn, a spot fill loudspeaker aimed at supplemental high frequency coverage for areas shaded by obstructions. Dual four inch diaphragm high frequency compression drivers provide substantial output suitable for mid to long throw applications. And the new DF443 is particularly effective in applications where supplemental HF coverage may be required due to occlusion from the primary loudspeakers by venue obstructions.
