A kick drum mic is a microphone specifically chosen and positioned to capture the sound of a bass drum. The challenge is distinct from other drum microphone applications: the kick drum produces a combination of very high sound pressure levels, significant low-frequency content, and transient attacks that require a microphone capable of handling all three without distorting or losing detail.
Why Kick Drum Microphones Are Specialised
Standard microphones — including most condenser microphones used for overhead and room recording — cannot handle the sound pressure levels of a close-miked bass drum without distorting. Dynamic microphones are better suited, but not all dynamics are equal. A kick drum mic is designed with a specific low-frequency presence boost (to enhance the thump and warmth of the shell resonance), a mid-range contour (to capture the attack and definition of the beater striking the head), and a high SPL tolerance that allows close placement inside or just outside the resonant head port without clipping. These characteristics distinguish purpose-built kick drum microphones from general-purpose dynamics.
Placement Positions
Three main placement positions are standard. Inside the drum (pointing toward the beater through the resonant head port) produces the most attack and click from the beater, with less low-end warmth. Outside the resonant head (pointed at the port or centre of the head from outside the drum) captures more of the shell's fundamental tone and warmth with less high-frequency attack. A combination of two microphones — one inside for attack, one outside for tone — blended in the mix is common in professional recording contexts. For purchasing decisions, see the buyer's guide.

Key Models
The AKG D112 MkII and Shure Beta 52A are the most widely used dedicated kick microphones in live and recording contexts — both designed specifically for this application, both available for £100–160. The Audix D6 is a strong alternative with a distinctive V-shape frequency response that produces a pronounced click and low-end thump. The Sennheiser e902 is a further option used extensively in live sound. For professional studio recording, the AEA R88 and large-diaphragm condensers (particularly the AKG D12 VR) are used in higher-end applications where the budget allows for more specialised selection.
Frequently Asked Questions
What is a kick drum mic?
It is a microphone chosen and positioned specifically to capture the sound of a bass drum. Dedicated models are designed to handle the extreme sound pressure levels of a close-miked kick drum, provide a frequency response that emphasises the attack of the beater and the warmth of the low end, and produce a usable signal without distorting or losing definition.
Do I need a special microphone for the kick drum?
For close placement inside the drum, yes — a purpose-built dynamic with high SPL tolerance is necessary. Standard condenser microphones will distort at kick drum levels when placed close. Standard cardioid dynamics like the SM57 can work in some contexts but lack the low-frequency character and SPL handling of dedicated designs. Dedicated kick drum microphones are significantly more effective for this specific application.
What is a resonant head port?
A hole cut in the front (resonant) head of the bass drum to allow microphone placement inside the shell. Many drummers and studios cut a port of 4–6 inches to accommodate a microphone inside the drum and improve control of the shell's resonance. A ported resonant head also reduces the build-up of air pressure inside the drum from each stroke, which can otherwise push the front head outward and create an unpleasant low-frequency boom.
What frequency response characteristics are ideal?
Most purpose-built designs have a pronounced low-frequency boost (around 60–80Hz for warmth and body), a mid-range scoop (around 400–600Hz to reduce muddiness) and an upper-midrange presence peak (around 3–6kHz to capture the attack and definition of the beater). This response characteristic is designed specifically to produce a useful, mix-ready signal without requiring extensive EQ in post-production.
Can I use a condenser microphone on the kick drum?
Outside the drum — at a distance of 30cm or more — a large-diaphragm condenser can capture an excellent picture of the bass drum's sound. Inside the drum at close range, most condensers will distort. Some specially designed condensers (the AKG D112 is technically a condenser variant called a back-electret) are built for high SPL and work well inside. Large-diaphragm condensers in room and ambient positions are commonly paired with a close kick mic in professional recording.
How do I connect a kick drum mic to a recording interface?
Via an XLR cable to a preamp or audio interface input. Phantom power (48V) is not required for dynamic microphones. Set the preamp gain so the loudest kick hits reach no higher than -6dBFS on the input meter, leaving headroom for the significant transient peaks that bass drum strikes produce. Some engineers pad the preamp gain down further to ensure no clipping on the loudest hits.
