dieter17 Posted July 4, 2015 Share Posted July 4, 2015 I recently purchased a used set of RF7's (and a RC7 for $1000 total). One of the RF7's has an intermittent crackling from both woofers. Any ideas what the issue may be? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
dieter17 Posted July 4, 2015 Author Share Posted July 4, 2015 It occurs at higher volume levels. Forgot to mention. Quote Link to comment Share on other sites More sharing options...

Mighty Favog Posted July 5, 2015 Share Posted July 5, 2015 (edited) High impeadence short? Make sure there aren't any stands of speaker wire bridging pos. and neg. Edited July 14, 2015 by Mighty Favog Quote Link to comment Share on other sites More sharing options...
dieter17 Posted August 9, 2015 Author Share Posted August 9, 2015 Okay, I swapped one of the woofers, and the issue is isolated to the right speaker. Both woofers crackle at higher volume on the right speaker only. Visually inspected the crossover but didnt see anything odd. Any ideas?

Matthews Posted August 9, 2015 Share Posted August 9, 2015 (edited) To clarify, you took a woofer from the left speaker and swapped it out with the right one and both the right speaker woofers still "crackle"? Have you swapped your left and right outputs to be sure it is indeed the right speaker and not the amp?

dieter17 Posted August 9, 2015 Author Share Posted August 9, 2015 Correct, I took a woofer from left speaker and swapped if with one from the right speaker (one that is crackling), with the same results, the right 2 woofers crackle at higher volume. I switched the speaker outputs, right speaker outputs to left, and vice versa. The right speaker continues to crackle. Seems it has to be the crossover? 1 Quote Link to comment Share on other sites More sharing options...
jjptkd Posted August 9, 2015 Share Posted August 9, 2015 Sounds like the crossover to me from what you've written. Maybe you could swap crossovers between cabinets just to be sure? If it is the crossover you can send it out to Bob Crites for diagnostics and repair, he is very reasonably priced and has a quick turn around time. Good luck! 1 Quote Link to comment Share on other sites More sharing options...

ricktate Posted August 10, 2015 Share Posted August 10, 2015 Could just be bad connection on woofer or crossover etc. Rick Quote Link to comment Share on other sites More sharing options...
