The RMS is 1000w. The t/s are close to what's listed on the ficaraudio site. I'll try to find more specific specifications with the options this one has but for now here is an explanation of the copper coils and BP option.
Copper coil (now standard) – The copper coil is a heavier coil and adds mass to the moving assembly. In comparison to the stock coil, or the flatwound coil, this has the smoothest transitions musically speaking. It is less likely to peak, and is a better overall sub for more Sound Quality based daily drivers. This coil is now STANDARD on the SSD.
BP Power - This option adds a machined aluminum compression plug to the pole which helps channel all of the air under the dustcap around the coil for better cooling. To aid with this increased airflow we also add 6 axial cooling channels in the top plate. Along with increased thermal capacity comes the addition of an extra spider and a changed spider pack. All of these features increase power handling from 200-500 Watts depending on the application.
