A:Answer I understand your question of what appears to be an extra "racetrack" speaker on the left side of this soundbar. I initially had the same concern.
There are five (46x90)mm racetrack drivers in the Bar 1000. I believe the two on the left are for the left channel (hopefully their amps are set for different frequencies). The two on the right are for the right channel. And there is only one racetrack speaker for the center channel that also has a center tweeter to the right of it.
The confusion is because looking at an exploded view, there appears to be two center channel racetrack speakers with one tweeter between them. But that is probably not the case, there is only one. Plus there is a space on the right-side last speaker for the LED display, that only adds to the exploded view confusion, because it appears to be missing a speaker.
Hope that helps!
