Sorry maybe I just Phrased it wrong. They claim around 200wpc acd. If you set your receiver to stereo(left&right)They claim around 400 wpc. So if you go into your receivers speaker settings and select "large" for the mains, then set the sub pre out to "off" the reciever will send all the signal to the 80's \:\)
Or if you want to still hear the sub you could leave it on and lower the mains crossover down to around 40hz
