box design or bad idea?

3) It has 8 times the physical coupling to the vehicle with over 1 lb per square inch verses the normal 0.13 lb per square inch of a normal box.

In other words, it has 8 times less footprint than a regular flat-bottomed box of the same dimensions.  So the weight is distributed in a smaller area.  But, how does that improve physical coupling to the vehicle?  Both boxes would have exactly the same weight physically coupled to the vehicle.  I don't get the physics of why narrowing that weight into two strips will transfer bass to the vehicle better.

Methinks they were really groping for superlatives with those three reasons.
