Fractal Audio Systems
The Torpedo stuff is an inaccurate load. A real speaker resembles a 4th-order network, at a minimum. The Torpedo products use a 2nd-order approximation to reduce component costs as this eliminates the large, expensive inductor that models the speaker mass. Our load is 4th-order. Furthermore our load is dynamic, the inductance varies with applied voltage like a real speaker. If you can't wait the Suhr reactive load may be a better choice.
