The kick drum big three: boom, smack, click
These are three key elements that can be used to describe the sound of a kick drum.
Boom is where the low end thud of the kick drum comes from. You can find a cleaner, modern sound boosting around the 50-60Hz area. A more traditional, ringing boom will be found a bit higher, perhaps in the 100Hz range. I typically use a normal, peaking band for the boom but you can experiment with a low shelving band here if your kick drum is lacking girth. Be careful not to overdo it with the shelf though, things can get blurry fast in the sub frequency ranges.
Smack is the primary attack of the kick drum. This is the frequency range that helps the ear identify individual kick drum hits. I like to start my search for smack in the 3-5kHz range. Microphones specifically tailored to kick drums will often have a bit of a presence bump somewhere in this range. I always use a peaking band for the smack and keep the Q parameter in the 1 to 1.5 range.
Click is exactly what you think it is. At first thought you might not attribute click as a quality desired in a kick drum sound. Click works in conjunction with smack to help bring a kick drum through a dense mix. This is the sound of the beater actually hitting the drum head. You can find the click up around the 6-8kHz range. A peaking band works well on the click (Q around 1.5) but a high shelf can be used to enhance the bleed of the snare wires in the kick drum mic.
Mud is not one of the big three because it is a bad thing! We want the opposite of mud in our mix, especially on the kick drum. You remove some of the mud and clean up your kick drum sound by cutting a thin band in the 250-300Hz range. I will often use a peaking band with the Q set to around 3.
