Wow, thanks for posting. I think I would expand my search to to TB ED or EA. Since I am pretty limiting in this vehicle using the OE chambers, I really need that long stroke to get the air moving better.
I really thought the JL W7 was the king of subs but it certainly looks there are some other lines out there since the last time I played the game. Now I just need to upgrade my Velodyne HGS18s with long throw drivers like this, OMG!! My home subs use an accelerometer so I would have to find out which they are using and would have to open the motor up to mount the sensor but could work....
