Shock-Late Posted June 25, 2001 Share Posted June 25, 2001 I would say that this is normal (tough it should only appear with very very very very high levels...gasp), assuming the dust cap is made from aluminium. If the dust cap is made from paper or polypropylene of wathever material who isn't supposed to conduct the heat out of the voice coil, I would say maybe it would better not to run them too long at those high volumes.

Guest BobG Posted June 30, 2001 Share Posted June 30, 2001 Most speakers are less than 2% efficient in converting electrical energy from your amp to acoustic energy. Where does all the rest of the amp power go? Heat. The voice coil in your speaker will be several hundred degrees F. The heat is conducted, even by the paper parts, to the dust cap where you can feel the elevated temperature. Quote Link to comment Share on other sites More sharing options...
