Dual 8 - inch 3D Beam Array Loudspeaker


  • OPD08 is a self-developed patent dual-compression coaxial loudspeaker system. Two 8-inch low-frequency units are arranged in V shape, and a patent double compressor is specially designed to form the optimum coupling horn structure. The front section is equipped with a dual loudspeaker waveguide transmission horn. High frequency and medium and low frequency are designed as coaxial structure, which can effectively improve the sensitivity of the system, avoid the uneven directivity caused by multiple acoustic centers, and achieve the unification of physical sound and image.
  • In the high frequency part, two 44-core Nd magnetic high-sensitivity compression drivers are used, coupled with 3D beam technology dual loudspeaker waveguide transmission horn, through sound equidistant division, forming coplanar coupling, optimum energy superposition, achieving greater sound pressure and more natural sound color restoration.
  • Two 8-inch neodymium magnetic units are used at low frequencies. Supported by dual-compression coaxial technology, the maximum sound pressure level of the whole box is 140 dB. A combination of patented technologies, compact structure, only a 10-inch box size, weight only 14 Kg.
  • OPD08 adopts self-patented array loudspeaker device, with rotatable horn, to form a vertical array, many superimposed, to meet the pursuit of greater sound pressure.
  • Integrative waterproof design, durable and wear-resistant polyurea spraying, complete accessories, flexible and convenient installation, so that the engineering application is more simple.
  • It can be combined with OPD12, OPD18B, OPD218B speakers, LAX DSP48, MT1300 power amplifier.
