SFM25A

Powered Composite Speaker/Monitor

1x 12″ Driver + 1.4″ Horn – 2500 Watts Program

The Acoustic Technologies SFM25A is a purpose engineered, low profile 2-way Stage Foldback Monitor system intended for high-end live production applications. The SFM25A features advanced transducer technology combined with the latest in computer aided design to deliver outstanding performance from a surprisingly compact enclosure.

The SFM25A employs a highly efficient 12” Neodymium L.F. transducer and a 1.4″ exit Neodymium H.F. compression driver coupled to a custom engineered asymmetrical waveguide, providing superior coverage with exceptional gain before feedback. SFM25A cabinets are available as mirror-imaged pairs or can easily be re-configured by the user as required.

The SFM25A changeover switch allows operation in passive mode using the sophisticated built-in dividing network, or bi-amp mode using the factory recommended Loudspeaker Management System settings. Connection Panels with dual Speakon Connectors are located on each end of the cabinet.

The extensively braced cabinet is constructed from premium grade void free Finnish Birch ply using precision CNC machining. Durable AcoustiCoate elastomer coating and a powder coated perforated steel grille complete the package.

The SFM25A is the speaker system of choice for any professional stage monitoring application requiring high performance from a compact lightweight enclosure.

The SFM25A enclosure is constructed of high quality Finnish Birch ply. A wide range of hardware, connector, mounting, grille and cabinet finishing options are available. The transducers are protected by a perforated steel mesh, lined with acoustically transparent foam, providing a durable visually appealing finish.

The SFM25A passive crossover provides a seamless transition between the transducers. The crossover frequency is selected to enhance the already superb performance of the individual components. Great care is taken to ensure that a phase coherent output is maintained across the entire audio bandwidth.

Sensitivity, Maximum Power and SPL measurements are conducted in accordance with the AES 24 Hour Pink Noise Standard. Acoustic Technologies reserve the right to alter or amend the SFM24, without prior warning in the interests of product improvement.
