The Prophile™ S coaxial loudspeaker provides the output capability of a dual 8 inch loudspeaker in an enclosure size typically associated with a single 8 inch, 2-way system. The S’s coaxial driver gives it the ability to provide a stable, high fidelity image at close range, and its dedicated low frequency transducer provides additional mid bass impact. Its horizontal orientation, small vertical dimension, and trapezoidal shape allow it to be positioned extremely close to ceilings and under balconies. The S’s low profile also makes it very useful as a front fill system when placed on the edge of or installed into a stage apron.

Fulcrum Acoustic’s TQ™ processing is an integral part of the S 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 S is an excellent option any time limited space is available. Its high efficiency results in impressive levels, and its 100° x 100° coverage and coaxial design make it especially effective in close quarters. Low frequency extension to 80 Hz allows the S to provide impressive impact and enables it to integrate well with subwoofers. This makes it an ideal choice for small live reinforcement or dance club systems, high intensity DJ monitors, A/V screening rooms, high output fill systems, and more.
