I noticed that I'm getting some bass distortion in one of my induction recordings. I'm recording what looks like a 6 in. woofer in a small 2-way speaker, using a good ol' Radio Shack telephone pickup. The midrange and highs sound fine and the live audio did not sound "hot" at all so I'm curious as to the how and why the distortion is happening. Do low-frequency magnetic waves need a different pickup coil shape or configuration? Do I need to wind my own pickups? ;D Thanks!
