Anonymous | Is there such thing as impedance in speaker cable? If so, is it possible to eleminate it and how? Also should I worry about impedance in interconnects? |

If you want to worry, worry about something worth worrying about. War, poverty and social injustice! Buy your cables from a decent dealer and stop worrying about impedance. |

Anonymous | <<why>> To educate myself. <<there>> Are you sure you haven't got mixed up between resistance and impedance as they are not the same. Are you sure you haven't got mixed up between resistance and impedance as they are not the same. <<it's>> That is well put Jan. I will remember that. |

Anonymous | <<you>> No. I just thought I heard it somewhere that they are not the same. <<consisting>> So what is reactance? |

Gold Member Username: Jan_b_vigneDallas, TX Post Number: 4928 Registered: May-04 | When referring to a speaker being a "reactive load", it means the combination of all the parts of the speaker's electrical equation; resistance, capacitance, inductance (the three items that add up to impedance), along with the electrical phase angle of the combined X-over and drivers. You can probably find "electrical phase angle" on the site C.L. supplied you. Reactance is used as a term that implies negative things when used to describe a loudspeaker. You want a speaker (as much as possible) to be a purely resistive load. The further it strays from that, the more problems the amplifier will have driving the speaker. As C.L.'s link provides, whether the speaker is an inductive or a capacitive load, will determine the problems the amplifier will face. http://lp2cd.com/audio_terms/a/index.html http://www.enjoythemusic.com/audioterminology.htm#S All those links were found on the internet. Try it, you'll learn something. |
