Reverse Sagg

jleaman · 24th May 2005, 01:20 AM

Does any one know what causes revers sagg in a speaker ? I know when you build a speaker IE subwoofer and fire the driver down it will sagg in that direction But mine they sit normaly and it is saggin inwards.. Does any one know why this happens. ?

What kind of drivers are they? If they are cheap, they likely have weak suspensions, a cost cutting method of getting a low Fs

It could be a negative DC offset... or a manufacturing problem.

Swap bwteeen left and right amp channels, if the sagg stays with the driver, then it's a driver coil alignment problem, if the sagg stays with an amp channel, then it's an amp problem.

Are these used or new? Are you the first hand owner?

second owner but the first owner was very good one. Ive never seen this before either.. Weird.

Is it stuck in that position? Or does it move with the sound? Does it bottom easily?

jleaman · 24th May 2005, 05:53 AM

It stays that way at all times. And it never bottoms out i never really push my speakers.. I dont need sound to be loud i listen at a nice level..
