SF1

SF1

A real problem solver for unique acoustic conditions, the SF1 is a two-way loudspeaker design housing two 8-inch low frequency drivers and a single 1-inch-high frequency compression driver. What helps set this speaker apart is its asymmetrical vertical dispersion, which allows for extremely even coverage.

Driver placement within the horn, in unison with a synergy crossover network, allows 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 while also allowing for high amounts of clarity at great distances. Furthermore, out of band harmonic distortion is limited due to the use of acoustic low pass filters. It provides even coverage front to back and nearly 180 degrees wide
