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.

Are you interested in a subwoofer capable of insane demos all day long? This may be the sub you are looking for. It features our newest motor design that includes an advanced cooling technology. You can run this under full power all day long and the coil temperature will never get much above 180F. When that cone gets moving again, within a second or two is has already cooled back down to room temperature.

It also features our new cone/coil/spider attachment design. It is an unbreakable joint that does not rely on glue to hold itself together. We use glue on top of that so you can be guaranteed there will be no issues.

The NEP Team Series NEO Subwoofer is fully CNC machined at our facility in Connecticut, and each one can be tailored for your application. Please contact us to discuss custom options.
