SP-12A SPEAKER INSTRUCTION

  • CHARACTER
    • SP-12A high-grade speaker is specially designed to aim at MT-12A mini integrated vacuum tube amplifier and room circumstance. It can be used with other HI-FI amplifiers.
    • Its Φ28mm big caliber althorn uses silken film which is produced by DR.KURTMULLER. Its coil uses heat-resistant materials which wrap aluminium in copper. It can support big range power and its tone colour is very graceful.
    • 6.5 inch (165mm) big caliber speaker unit uses in low frequency. This speaker unit uses 3 inch (75mm) large sound coil which contains special technology.
      • It uses oblate wire which wraps aluminium in copper. It can avoid inner stress, effectively increase the reliability and life of sound coil and raise conversion efficiency of electricity and sound.
      • High capability lanthanon neodymium magnetism material can effectively improve density of flux; Advanced auto-wind-cool technology can reduce temperature rise of sound coil and magnetic road and raise power endure ability.
    • Circuit and parameter of network is designed by analysing and computing through computer emluator. Low frequency uses –6dB concisus network, high frequency uses 2 factorial network. Inductance coil is hollow coil which uses non-oxygen copper wire. High-grade metallic polypropylene filmy capacitors are used in network.
    • It adopts linearity phase design and relatively balance design in whole box in order to hanker for real phase smoothness overage and avoid man-made modify and romance. Appearance of sound box is simplicity and taste.
    • This sound box can be used in big power amplifier and large dynamic music.
