Speaker Cable : maximum runs

Maximum cable lengths for :

• Low impedance (2, 4, 8 and 16 ohm)
  • Quality
  • 3 dB loss, may sometimes be an alternative to a transformer line system
• High Impedance
  • 70V
  • 100V

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.

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
