longdrive03 Posted January 3, 2013 Share Posted January 3, 2013 Has anyone experienced a rattle at certain frequencies (around 100-125Hz) in the RSW-12? Could it be the amp not being secured properly? Doesn't affect the bass output but it is noticeable. The cabinet is not very well braced. Thanks.

bhenry Posted January 3, 2013 Share Posted January 3, 2013 I've noticed rattles in objects around my house, like windows and doors BECAUSE of my RSW's but not from them. I would check all visible screws for tightness to start. Quote Link to comment Share on other sites More sharing options...
JJkizak Posted January 4, 2013 Share Posted January 4, 2013 Ditto. If you pump it with frequencies below 15-19 hz at high levels (98 dbm SPL) you will get some funny stuff. Then again it might be my ears. JJK Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted January 4, 2013 Share Posted January 4, 2013 Something is loose since you notice it with certain frequencies. That sub has a passive radiator so it will not reproduce the 15-19 Hz stuff and that is not the problem. Quote Link to comment Share on other sites More sharing options...
longdrive03 Posted January 4, 2013 Author Share Posted January 4, 2013 Thanks guys. I noticed there are some small "fins" on the back of the amp that is screwed to the vertical brace and that might be the source. I'm not sure if that is a heat sink or what. I am concerned about bracing it and possible heat problems from the amp. Here is a pic I found on internet. The rattle seems to come from the two black covers that screw down. The area where there are four openings might be the culprit. I have tightened the four screws down and removed the amp from the vertical brace and tightend down the screws on the back side. Any idea how to insulate the black covers and not harm the amp? Quote Link to comment Share on other sites More sharing options...
Rhetor Posted January 4, 2013 Share Posted January 4, 2013 Noticed a rattle in mine too at higher volume . . . Turned out to be the grill cover . . . Took it off . . . No more rattle and look nicer . . . Just have to dust,more often. Quote Link to comment Share on other sites More sharing options...
