We are pretty excited about this new product also. It has been in the works for almost two years and it is nice to see it finally come together.
The voice coil in the sub is a dual voice coil so it takes the right and left channel independently from the amp. The passive sub is like turning your AudioByte main speakers into a 3 way design. The efficiency of the sub is the same as the AudioByte mains combined in the flat setting. The half and full boost setting we raise the subs output by 3 db each. So the sub is in fact 6 db more efficient than the 2 AudioByte mains combined and we are padding it down to get the flat mode. Since it works like a 3-way system there is no draining of power from the amp in order to run the sub. The output per watt remains the same it just adds in those lower frequencies.
