[QUOTE="adulbrich, post: 8426449, member: 661255"] If you were serious: As you try to feed a coil more power, it heats up. This causes the impedance to rise and is *one of* the factors that causes impedance rise. Higher impedance creates more heat, which creates higher impedance... and just keeps going up as you add power. I'm sure I'm forgetting something important with this explanation, but I'm sure someone else on the internet will jump in and correct me. With phase issues, it gets complicated. There is more cancellation when you have more drivers. Have you heard of active noise cancelling headphones? the drivers produce a sound wave exactly inverse the one that the microphone picks up. This pretty much negates it and the noise you hear is far less audible. It's late and I just got home from a 9 hour shift, so pardon me if I didn't do a fantastic job explaining things [/QUOTE]
