SAMMI 1 Inch (25.4mm) Bolt on Titanium Horn Driver (SM107

The SAMMI SM107 is an imported high performance 1″ throat compression type high-frequency driver for use as a high frequency component in professional high quality sound reinforcement and reproduction applications. The SM107 offers exceptional high frequency performance: High acoustic output 106dB/1W/1m when coupled to the SH402 flare. Wide frequency range 800Hz to 17KHz when coupled to the SH402 flare. 50watt power handling above 800Hz . When attenuated to a typical sensitivity of 100dBSPL the input power handling at the network input terminals is 200W relative to 2.83v/8-ohm reference.

 This unit must be connected to a system via a frequency selective device the “crossover” which may be passive or active-electronic type. We recommend a minimum 12dB/octave high- pass filter, refer our computer-aided design filter networks which are designed to meet specific target response, however in demanding applications a higher order network is recommended and necessary
This driver is a bolt-on type and three equi-spaced 0.25″20UNC threaded holes on a 57mm PCD are provided. Additionally two 0.25″ -20UNC threaded holes on a 76mm PCD.
The diaphragm is terminated with push spring terminals, observe polarity.
