this tells me nothing about eD. If the cone had been becoming detached (which is what was happening) a year ago you would have been singing a much different tune when you would have to wait about 4 months to get your driver back. believe me, it happened with my K. and i got a different subwoofer back. you are satasfied because they were able to immediately replace your driver with the new line. that was not the case back in the day. eD is wrong, the only good thing it has going for them are the amplifiers (made by valued electronics), and people who are unaware of the truth.
