Yes it looks like the speaker placement on my computer is the same, with the subwoofer on the bottom right of the computer ( your right when facing the screen), and the pins are definitely the same as far as I can see. well, to be honest I'm happy enough with a stereo setup as long as all 4 speakers + subwoofer are active (which they are), in fact the most enhancement to the sound occurs when you have at least 2 speakers and the subwoofer active.
