How i open my panasonic sa-ak320?

i need to open it up to fix some thing but i do not know how there are these little screw parts on there and i think there fake because i tried to unscrew them but the dont move but there must be another way to open it up some how but im not to sure there are little parts on the bottom that seems you can take a knife and open it like a crow bar but im not to sure that if i do that i will break the glue and the wood that they have used to put it together also from the looks of it it seems that it can open but i am not to sure and i do not want to end up breaking one of the speakers by trying to open it not knowing how to do it at all what so ever and also its the right speaker if the matters at all depends on what way you are facing it when you face its the right one when you are behind the speaker it will end up being the left one so im not sure if it matters what side you are on but either way they both seem to open the same way from the looks of it any way im just fixing a miner part
