Just want to point out some key differences between this and the older LMS-5400
this particular driver we made ahead of schedule. As already noted, the AP cones are not in, however the 18" Black TC cones are the same. Also, the mag boot is not in either. Beyond that, its the full LMS-Ultra.
The suspension has been substantially improved to increase its durability. The spider cloth is thicker and the phemolica glue in the spider are stiffer. We also increased the gauge in the leads to prevent them from heating up as much to prevent burn through.
We also changed the VC to improve the heat transfer from the coil. The LMS -Ultra can dump heat faster than the older LMS so it should be able to deal with compression better, not that the old LMS-5400 was a slouch.
One of the other major differences is every AP product comes with a full lifetime warranty. We wanted to make sure customers feel secure no matter what. I know there are a lot of trendy drivers that have NO warranty and we're really taking aggressive approach against the make-it-as-cheap-as-possible trends.
Anyway, we just opened up the AP forums too, we hope all the old TC customers come back and say hello or ask any questions you may have.
