The SF1 is a two-way loudspeaker design housing two 8” low frequency drivers and a single 1” high frequency compression driver. The SF1 lends itself to use in rooms with challenging acoustics as it features an asymmetrical vertical dispersion. This allows for extremely even coverage.

Driver placement within the horn, in unison with a synergy crossover network, allow for proper phase alignment between frequency bands. This permits the physically separated bands to combine and emerge from the horn in synchrony, greatly reducing off axis distortions in frequency response, allowing for high amounts of clarity at great distances. Furthermore, out of band harmonic distortion is limited with the use of acoustic low pass filters.

The 13 ply Baltic Birch is used throughout. The enclosure is encased in Polyurea for protection from impact and atmospheric conditions. A strengthened outdoor finish is available for long term exposure to rain and sunlight.

The cabinet is retrofitted for use with the MB50 Fly Bar via four M10 rig points on the top side. Two M10 yoke points provide mounting for the BRKT-SF1 U bracket on the sides. Ten M10 rigging points are distributed throughout four sides of the cabinet.

Even coverage front to back and nearly 180 degrees wide
