But everything on them looks perfect and brand new. But when power gets put to them they make a rattling noise. there dual 2ohms and have never been ran on anything other then a rf t1500.1bd. i need some help on fixing the annoying noise so i can sell them. iv changed boxes and coil tested them allready.

bassl0va Posted November 24, 2010 Report Posted November 24, 2010 The coil has probably semi-unwound from the former. If that's the case, it is screwed.

Skullz Posted November 24, 2010 Report Posted November 24, 2010 Could have a separated surround from the cone, could have separated the spider or even have the dust cap coming loose, just take your time looking at everything and giving a gentle push or pull on the cone and see if anything is loose or separated. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2
89capricebass Posted November 24, 2010 Report Posted November 24, 2010 does it happen at low or high volume?

94retta(219) Posted November 24, 2010 Author Report Posted November 24, 2010 i can push the cone in and out fine on both woofers, and this is only happenin bad to one sub. one does it a little bit but not bad. idk if this means much but if i tap on a corner it makes a hallow tink noise... no sound of coil rub at all when its pushed in the center. it also only happens at high volume.

Maybe the spider came unglued from the cone and slaps the cone at high volume? Rest In Peace mother. January 22, 1955 - February 14, 2013 http://www.stevemeadedesigns.com/board/user/35351-megrch/
94retta(219) Posted November 26, 2010 Author Report Posted November 26, 2010 Thats not it either! its really strange. like i said it makes that tink noise... like when there movin it sounds like my car is rattling, but its deff the subs. it sounds exactly like takin somethin plastic and hitting it against a empty can. im gettin pissed with it honestly.

TeamHT Posted November 26, 2010 Report Posted November 26, 2010 check the leads. slapping against the cone? Tell me...does this smell like chloroform to you?
