Here’s a pretty cool way to ramp up the sound of your drum recordings that’s kind of subtle, but still pretty significant. AÂ typical kick drum mic doesn’t pick up the real low sub frequencies as well as you want, only because the diaphragm just isn’t physically big enough to do it. At some point along the way somebody figured out that you can wire a standard speaker to work in reverse as a microphone, and since it’s essentially a massive diaphragm, it gets all the low sounds you’re looking for (and none of the high ones – you’ll need to blend it with a D6, D112, or Beta 52A to get a full sound).
Furious Glenn Fricker, in a rare rant-free tutorial video, calmly explains what a subkick is useful for, demonstrates how to use one and what it sounds like, then tells you how to build one of your own!
