Does this woofer has a dual spider suspension? (i.e Eclipse) If it does than I doubt it will rub like I stated earlier. The stiffness of the cone really wont be a part of the downward movement of the suspension on a woofer (its plays a part, but not one that effects the travel of the coil)
The stiffness of the suspension sure will though. I have a "quality" new in the box JL w1, if you apply downward pressure to the outer edge of the cone it will rub the vc former against the pole peice. I tried this on and eclipse and the dual spiders kept the coil completely in line.
You have to remember the cone and coil are one "solid" peice that fluctuate with polarity in the motor structure of the woofer and are controlled by the spider and surround. If the suspension is weak (weak maybe a a bad word here), it is possible to rub.
Then again maybe his Perfect woofer was not so Perfect after all....lol
Try the battery test and see what happens.
