6444johnf Posted December 19, 2022 Share Posted December 19, 2022 Not sure if it makes a difference but should each driver be fused, or should it be all in one? Looking like a 2.5 Amp quick blow fuse is correct, maybe. Quote Link to comment Share on other sites More sharing options...

Looking like a 2.5 Amp quick blow fuse is correct, maybe. Why so large a value. I use 1 amp quick blow. If memory is correct Klipsch once selected 1 1/4 amp quick blow for a LaScala. 001 is correct in that fuses should not be required and could possible degrade the sound ever so slightly, indistinguishable for most though including me. I do it because I build lots of audio gear and who knows, I do make mistakes and do not want to be buying drivers or speakers. Accidently pulling input cables while amp running will give you a nasty sound that is subject to blow my 1 amp fast blow on occasion. Probably not hurt anything but a fuse assures it does not especially that delicate tweeter. 1 Quote Link to comment Share on other sites More sharing options...
Racer X Posted December 19, 2022 Share Posted December 19, 2022 Suggest 1.5 amp fast blow, in line on speaker wire. 2 Quote Link to comment Share on other sites More sharing options...
JohnA Posted December 21, 2022 Share Posted December 21, 2022 A 2.5A fast blow will be fine and will limit the total power to about 100 watts. Outside of pro audio, they don't need it. Quote Link to comment Share on other sites More sharing options...
