did you have them cranked when they started sounding weird?

check the connections, "amp, and speaker terminals"

[This Guy]

do everything uncooked said. Also try pressing on the woofer cone, do you hear a scraping sound coming from it when you push it in? If it doesn't don't check only the outside connections, but also the internal ones and make sure they're all connected.

[aimen]

yes i check the connections all fine

how do i check internal connections

when i push it in while playing the scraping sound decreses or at low volume completly goes off but also the volume of woofer decreases

but when the woofer is not in action, not connected to amp, not playing any thing, theres no scraping sound but when i press it in i hear the scraping sound, its like the cone paper is scratching something, if i push it justt from one side of the woofer theres no scraping, when i press from the opposite side there loud scraping, when i press from center theres a meduim scraping sound

i noticed that if i pull the rubber surround a bit outwards from one side ( the side opposite to loud scraping side ) there a huge improvement and the woofer doesnt sound dull as it sounds when i push it in

is this the correct/permanent way to fix it

thx

Sounds as if you overpowered your speakers a little. What seems to have happened is that the coils melted and became deformed (through mechanical failure, the coil would be scraping the magnet). Otherwise, this should not happen under any normal circumstance (or listening at moderate volumes, anyways). This happend to me before when I actually took a driver apart from a cheap speaker by seperating the magnet from the cone (for experimentation purposes). The coil actually melted the "paper" cylinder and caused it to scrape against the magnet. I wouldn't bother trying to fix it doing this, taking it apart you've pretty much ruined it. Buy better speakers that can handle more power.

Or, when I was younger and couldn't afford a darn thing, I acually took a cloth and placed it behind the actual driver (between the spider and the cone) pushing it out a little to prevent scraping. My music seemed to have played fine and I noticed little difference...

[aimen]

well i guess thats what happened
it was used carelessly and was kind of over powered as well

after pulling the rubber on one side i have reduced the scraping sound alot, at moderate volume average listner wont fell any annoying sound from it , one can only feel the differance while doing side by side comparision with other fine speaker, or at loud volume,
well i think its not that bad
while playing both at a time they sound fine

thx
