The Prophile L is a bi-amplified, 3-way coaxial loudspeaker that provides the output and pattern control of two 15 inch transducers in an enclosure size that would typically house a conventional 2-way system. The L’s dedicated low frequency transducer was selected to provide maximum mid bass impact, and the coaxial driver’s conical horn is ideal for the wide by wide coverage requirements of near field applications. The ultra-low profile, horizontally-oriented enclosure may be mounted close to ceilings, in front of balcony fascias, or along a stage front with minimal effect on sight lines.

Fulcrum Acoustic’s TQ™ processing is an integral part of the L design. Sound, innovative acoustical design combined with state of the art digital processing leads to exceptional clarity and precise transient response, even at very high sound pressure levels. The required digital signal processing can be provided by one of many supported platforms.

The L is an excellent option any time visceral impact and/or high SPL is needed from a package less than 48 centimetres tall. In addition, its coaxial design gives it the ability to provide a stable, high fidelity image at close range. This makes it the perfect choice for live reinforcement or dance club systems, high intensity DJ monitors, A/V screening rooms, high output fill systems, and more.
