bfmcvs1 Posted September 5, 2018 Share Posted September 5, 2018 I currently have 2 AW-650s and 2 AMR-650s connected to a Yamaha N303 receiver. Everything had been working well till today. I noticed that on 3 of the 4 speakers the sound is very muffled. So to test the speakers I removed the one clear speaker and connect each of the 3 muffled ones to what was the one good connection. No change as the speakers were still muffled. So I ran a new cable just to make sure to each of the muffled speakers and still no change. So am I basically out of luck and the speakers are blow?

willland Posted September 5, 2018 Share Posted September 5, 2018 Sorry about your bad luck but you may have caused a thermal event. Running two pairs of speakers, A+B, your amp will see them as 4ohms minimum. Just a shot in the dark on my part. Bill Quote Link to comment Share on other sites More sharing options...
JohnA Posted September 6, 2018 Share Posted September 6, 2018 Sounds like burned out tweeters. Too much power to the tweeters from running them too loud or too much amplifier clipping. Perhaps you got lucky and only blew a fuse in the tweeter circuit. Quote Link to comment Share on other sites More sharing options...
