Gareth, I believe it's a 6dB drop for the inverse square law.  If that is correct, then it should be 125dB at 3 feet.  Unless I have the math wrong.

still well within the realms of a pro sub

yes you are right...sorta.  But, I think you are trying to imply that the 95 db measurement was on purpose and the vehicle was at 100% volume?  That is not the case, the owner was simply messing around with the van and it wasn't even pointed toward the microphone.  That was just an observation and was meant in no way as a "specification."

Excellent point, Tim.
