The RX599 is a high efficiency, high fidelity coaxial loudspeaker that provides output capability typical of a much larger loudspeaker. The transducer’s high efficiency and horn-loaded HF compression driver give the RX599 a surprisingly high output-to-size ratio, and its broad 90° x 90° coverage is particularly effective in close quarters. The RX599’s compact enclosure may be mounted close to walls or ceilings, under balconies, or along a stage front with minimal effect on sight lines. Its small size also allows it to be readily concealed within a venue’s architecture when the loudspeaker must be hidden from view.

Fulcrum Acoustic’s TQ™ processing is an integral part of the RX599 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 RX599 is an excellent option any time moderately high SPLs are required but limited space is available. Spoken word sounds very natural, and the coaxial design assures that this remains so even off-axis. Low frequency extension to 100 Hz enables it to integrate well with subwoofers for full range music reproduction. The RX599 is a perfect choice for delay fill, background music, and speech reproduction systems, which makes it ideal for houses of worship, theaters, restaurants, nightclubs, museum kiosks, theme parks, and more.

The RX599 is nominally 16 ohms.
