Spark amp speaker sensitivity?

  • Hi, does anyone know the sensitivity of the speakers in the Spark amp?


  • Hard to say as they are custom drivers so no manufacturer info.

    However if spark user manual is to be believed and:
    Amp is true 40W
    Max sound pressure level: 116bB SPL @ 1M

    Then online calculator suggests they are around 97dB SPL (1W/1M)

    Depends how they measured sound pressure and true output wattage of amp so that calc could be off by quite a bit.

  • @jonathane40 The speakers have been discussed in other threads, and also in the Spark Amp Mods group at facebook. The speakers are 4-ohms, with a range from 20 - 20,000 Hz.
