Topic: rule stipulation
Would a passive radiator be considered a sub as far as number or cone area? No power can be applied to it, and by itself is useless, so its not technically a sub. As far as I know, there is no rule saying you can/can't use them or if they constitute cone area or not.

In dB Drag racing a passive radiator is not considered a sub. (I think they call it a port) I'm not positive about NSPL but I would think it is not considered a sub.

Thanks. If that is the case in dB Drag and NSPL, why are they not used? If its not a sub, and moves air, that sounds like a good thing to me.

I think because at HIGH levels, they may rip, or impede the air movement.www.bordermotorsports.com

Not to mention that they are quite a bit more difficult to tune than a standard port.
