Our new designs have shifted the emphasis to natural system acoustical gains over driver efficiency in free air. The "Unusual" looking T/S specifications shows where the shift in design philosophy has taken us. We are able to extract system efficiency along the frequency range that you want a subwoofer to operate in. This is true for all of our subwoofers. Each of our subwoofer lines has a different reason for being. Some focus on lows, some on more musical bass...

Take the Team Series 18" as an example. This chart shows the natural frequency response of an NEP Audio Team Series 18" subwoofer in a simple 7 cu ft. ported box tuned to 24Hz in half space without any filtering. There is a huge gain over the entire frequency responce that our sub is going to operate in. When put into a vehicle, the cabin gain will be on top of the gain we have already given the sub, and it ends up having a rather flat response when the two gains combine. Traditional designs are leaving a massive amount of acoustic power off the table.
