Hello Mike,
The wireless rear speakers of the HW-Q930B are best to be used behind you, but you can position them to the front if you need to.
You will need to use the provided Soundbar remote and press the SOUND CONTROL until you see SURROUND SPEAKER. Press UP/DOWN to change between Front/Rear placement for the rears.
The speakers are labelled LEFT/RIGHT and will need to placed correctly if you change then to the front.
