I think by simple logic you can figure out they are not going to do much good.

When speaker drivers are designed they pay A LOT of attention to resonance. I think its quite safe to say that if an application of a few dots made significant improvements to the resonance and indeed the sound, they would do it! Also the fact that most speaker drivers are different to each other means that applying the same treatment to each is unlikely to help much; their brake up points and so on will all be different to start with.

As for putting them on windows and so on? well I seem to remember someone reporting that insulating tape across the windows helped a lot too! No need to pay lots'a money for these. Tape even comes in nice colours!
