How do I get rid of the jingling sound from subwoofer?

Question

At the basement, I have a suspended ceiling. However, when I play my home audio, this ceiling starts shaking and makes a jingling sound, which is really annoying. And that's only with 70-watts system. I'm about to set up a 1500 watts subwoofer in here yet it I'm sure it'll shake the ceiling so badly that I won't want to go even 1/10th of the possible power. So, the question is - what can I do so that the celining does not make any annoying sounds? Setting up a permanent ceiling is out of question, since I need to have access to all the pipes and everything else. Setting up the sound isolation under the ceiling won't do either, since the ceiling is already low as it is, and I can't bring them any higher either. Changing the ceiling completely is too expensive. What else can you recommend?
I read more than enough about setting up audio systems, so please answer accordingly, about the ceiling only.

The problem is not at one point - the whole ceiling is shaking, depending on where the subwoofer is placed. I actually have 3 subwoofers right now in the room, and the noise comes from the spots right above the subwoofers.

Answer 1

put foam on the other side (the side you are not looking at) I shuffed 2 camping mattrasses on mine and it worked!

Answer 2

You might possibly want to try crafting some ridged hangers from some solid pieces of metal. Just measure each location to be sure you get the proper length so the ceiling doesn't look funny afterwards.

Answer 3

you cannot possibly stop this from happening given the restrictions you mentioned. Either move your set up elsewhere, or take down the ceiling

Answer 4

theres probably something loose up there. maybe its one of those thick metal wires they use for those types of ceilings. get up there while the sound is on and find whats jingling, then tighten it down.
