• Maximum speaker cable lengths

    Maximum speaker cable lengths for :


    • Low impedance (2, 4, 8 and 16 ohm)
      • Quality
      • 3 dB loss, which could be an alternative to a line transformer system

    • High impedance (systems with line transformer)
      • 70V
      • 100V




    Low Impedance


    Results are for a total damping factor of 25, using an amplifier with a damping factor of 400 and signa loss of 0.3 dB. 25 is the minimum damping factor for a "quality installation". For higher quality, specially for bass, the above recommended lengths would be halved



    Results are for a signal loss of 3 dB and are in practice independent of the amplifier damping factor


    Alta Impedancia (High Impedance)


    Results are for a signal loss of 1 dB. For 3 dB loss, multiply the maximum lengths by 3.5



    Results are for a signal loss of 1 dB. For 3 dB loss, multiply the maximum lengths by 3.5


    NOTE: A comma is used as decimal separator instead of a colon. Multiply the resistance/100 m value by 0.3048 to get a value for resistance/100 feet. Multiply meter lengths by 0.3048 to get lengths in feet.

    Intelligibility and its measurement

    1. What is intelligibility?

    The state or quality of being understood. It can apply to an idea or a writing, but in our context it relates to the spoken word and, less commonly, to music.... Read more

    Choosing loudspeaker cable

    The importance of cables for the connection between the amplifier and the speaker is often controversial. Hi-fi aficionados spend fortunes on cables that promise spectacular results, and our short auditory memory and subjectivity lead many to confirm these improvements in their systems.... Read more

    Constant voltage systems (70V, 100V lines)

    Constant voltage, high impedance or line transformer systems are often a somewhat confusing concept for professionals used to rock and roll. They are actually very simple to design, among other things because they are intended to be installed by electricians and the like, with little experience in sound systems. In this article we will try to clarify the simple concepts needed to understand this type of system.... Read more
