i've always wanted to know what it was meant by supercharged?

The specs don't change much for box building, the energy of the motor system is increased. In many box modeling programs, the model will show decreased bass due to more control on the voice coil movements. This is an outdated transducer/box model that originated when power amplifers were much smaller and most listening was done a 1-5 watts of power.

In this type of model, the box compliance plays a major role in the total system Q, and too much damping on the coil puts the brakes on low frequency.

In todays systems, the amplifier power dominates the whole system, the resulting high forces generated are more and more difficult to control. Our real world testing proved that overdamped systems, where the suspension and motor have tighter control, allow the cone to move with the original source signal. Traditional systems that look good on the modeling programs always lose control at real world power levels and cannot track the original source signal.

DD speakers will play tight and controlled throughout the power bandwidth. The supercharged versions add even more magnetic energy and you will hear tighter, even cleaner bass.

**** bro can you be a little more specific? lol thanks for clearing that up

Apparently it's just an option that gives more motor force and less distortion with a big fancy description

Would disagree with this. TS parameters do a fine job of predicting response and if they're "outdated" why doesn't someone come up with some new system of predicting response? Furthermore, I'd say that with the recommended DD box, the box and port are the dominant factors in response. It just so happens that subs with stiff suspension and strong motors perform very well in that alignment. That used to be what they claimed design philosophy was. Design and market a sub around the box.

Typically most features that create less distortion reduce efficiency, though I would believe more motor force.

Don't get me wrong, I love me some neo and am a big fan of strong motors. I'd get supercharged option if I were to use DD subs. GLWS.

How big of a box do these things need? I also have an Fi SP4 if you're interested. I have cash too.
