    Hi,

    Im trying to workout the frequency range of the drivers?

    803S - Floorstanding

    • 3-wy vented box system
    • 150mm (6”) Kevlar cone FST midrange
    • 25mm aluminium dome high-frequency
    • 2 x 180mm (7”) Rohacell cone bass
    • Sensitivity: 90dB spl
    • Frequency Response: 35Hz - 22kHz ±3dB
    • Recommended Amplifier: 50W - 200W
    • Dimensions: 1063h x 291w x 433d 41kg

    1. 25mm aluminium dome high-frequency = 4kHz to 22kHz
    2. 150mm (6”) Kevlar cone FST midrange = 4Hz to ?
    3. 180mm (7”) Rohacell cone bass = ? tp 35Hz

      150mm (6”) Kevlar cone FST midrange: Do they all run on the same frequency?
      by nick.h
      Hi,

      I have noticed the 804s/803s/803d/802d/801d/800d all use the 150mm (6”) Kevlar cone FST midrange driver. Are the crossover for this all set to be the same? Do they all run in the same range?

      What about the 805s the 6.5" Kevlar, what frequency does it run at?...

      The cone of a loudspeaker driver refers to the diaphragm or membrane that moves air to produce sound. A cone is distinguished from a dome in that it is almost always a concave shape. It is a crucial component responsible for converting electrical signals into mechanical vibrations, resulting in the creation of sound waves. The cone typically consists of several layers and materials, each serving a specific purpose.
