How to open Harman Kardon soundsticks speakers!

I had a similar problem with my Sound Sticks. One of the little speakers had come loose from it's bracket, probably from some rough handling during a recent move. I was able to use a pair of plastic spudgers to gently pry off the top half of the housing. From there, it was just a matter of snapping the little speaker back into its brackets. I replaced the housing and it seems to stay in place, but not securely. I'll probably use some clear tape to secure it if it becomes a nuisance.

Put some petrol over the edges wait for few minutes the with it will come with gentle pull
