Not the same inductance as a curly instrument cord. No inductive effect with coiled speaker leads (or mains leads) as the current flows both ways. The danger is overheating at high power due to reduced airflow around the coils. Quote Link to comment Share on other sites More sharing options...
agedhorse Posted September 17, 2021 Share Posted September 17, 2021 (edited) One of the biggest issues with the coiled cords is that they are usually manufactured with twisted "foil wrapped around a fiber core" tinsel wire which has a smaller than expected cross sectional area. What appears to be say 18 AWG may in fact be 22 AWG in reality. (AWG = American Wire Gauge). Because of the cylindrical wrapping and twisting in the tinsel wire fabrication, the inductance can also be higher and depending on how it's fabricated (twisted or braided), even the capacitance can be higher too.

beans-on-toast Posted September 20, 2021 Share Posted September 20, 2021 Excessive weight from a too long speaker cable can be a problem. Speakons offer some strain relief, ¼” plugs are more of a problem although some do offer some relief. A looped speaker cable should have the loop supported to relieve stress on the connectors. 1 Quote Link to comment Share on other sites More sharing options...
