The One Systems ONE.SP12DTM is a weather-protected 12 two-way horn-loaded sound projector solution suitable for professional audio applications indoors or for inland environments outdoors. The system’s transducers include a 12 woofer with a 3 voice coil and a 3 compression driver with a pure titanium diaphragm coupled to a large-sized 60° x 40° horn. Thanks to its 600 watt continuous power handling and high sensitivity, the ONE.SP12D provides high acoustic output capability, tremendous projection and installation flexibility in a reasonably-sized package. The ONE.SP12D’s enclosure is made of strong, UV-resistant, molded High Density Polyethylene (HDPE). Its specially built components and use of stainless steel suspension hardware ensure long useful life and safety for direct weather applications. An optional pole mount bracket is also available for customized mountingsolutions. This speaker is also available with an internal 400 W, 3-tap autoformer (ONE.SP12T).

The ONE.SP12D provides high vocal intelligibility and tremendous acoustic output capability from its compact enclosure. Its large compression driver with titanium diaphragm delivers extended response with excellent transients and permits a lower crossover frequency for a more coherent sound. Its large-sized horn provides precise pattern control and long projection capability. The woofer’s specially treated cone and surround provide superior resonance damping and resistance against moisture and dry rot. The ONE.SP12D’s high power handling and sensitivity provides 130 dB continuous, 136 dB peak output capability.
