For years the reviews on laptop speakers have been far from kind. I can't guess if you are trying to make do with the stock laptop speakers. For me, I have to use externals and sometimes a receiver to get something acceptable.

I have a Samsung Series 5 550P5C 15.6-inch Laptop. Since I have used it, I haven't been able to make full use of the JBL speakers. The sound seems far too bassy and muffled. When going into the speaker settings, it's almost as if one option is the subwoofer, and the other the normal speakers. I only can pick one or the other, when I have a feeling that both need to be working at the same time to get the most out of the speakers. Can anybody please help me?
