Faulty speaker?

[Rozga123]

Ok so i bought my speakers ( Genius gx gaming sw-g2.1 3000 ) a few months back, and since then i had no issues. But recently the left speaker started acting strange. It`s buzzing when any high or deep sounds are played, such as rumbling. It sounds very similar to a geiger counter but in the rhythm of whats being played. It`s not that loud but noticeable enough to be annoying. Also i noticed it stops that when i press directly on the speaker itself, but continues when i let go. I tried pluging and unpluging everything and messing around with the bass controls, but nothing seems to work. At this point im wondering if its just a faulty unit and if i should get it replaced. Any ideas?

I would turn the PC off and spray all the audio connections with a special spray, that look like this
