Fulcrum’s Prophile series was developed with creative and technical guidance from John Lyons. John’s goal was to create a line of loudspeaker systems that could be integrated into a variety of architectural motifs, while meeting the highest performance standards for music/entertainment venues. Input was based on John’s experience with audio systems for some of the largest, most successful clubs in the USA and abroad.
The Prophile Series of high-output music systems are at home in any installation where architectural aesthetics preclude the use of larger, vertically oriented designs. Their low profile, horizontally-oriented enclosures have an elegant appearance, and may be mounted close to ceilings, in front of balcony fascias, or along a stage front with minimal effect on sight lines. Some models are even optimized to conceal in soffits.
Next generation coaxial transducers give Prophile loudspeakers the ability to provide a stable, high fidelity image, and Fulcrum’s Temporal Equalization™ technology adds studio-monitor-class transient response. The surprisingly compact systems are a perfect choice for nightclubs, live performance venues, A/V screening rooms, as high output fill systems, and more.
A number of companion subwoofers, including direct-radiating and horn-loaded designs, provide solid low frequency support and offer many system configuration and design options.
Product drawings, processor configurations, EASE data, and more may be found on the Support page.
