TC is the buildhouse, but Mike from SS designs his motors and does all custom work I believe.

Nope. Standard TC9 motor on the Rl-p. The Rl-i is a textbook TC2+ woofer. The Rl-p was slightly modded from a stock TC9; dual spiders, different surround, slightly stiffer suspension......mainly things that will enhance durability.
