Sennheiser E 901 Semi Cardioid Condenser Instrument Microphone for Bass

Condenser Precision for Kick Drum and Bass

The Sennheiser E 901 is a boundary-layer semi cardioid condenser microphone engineered for placement inside kick drums and bass instrument enclosures. Its unique design sits flat on the drum shell or cabinet floor, capturing the full low-frequency body of the source with a level of detail and warmth that traditional dynamic mics can't achieve. If you want your kick drum to feel as powerful in the mix as it does in the room, the E 901 is the tool for the job.

Key Features

• Semi cardioid boundary-layer capsule — wide, even pickup optimised for placement inside kick drums and bass enclosures
• Frequency response: 20 Hz – 18 kHz — extended low-end capture with natural transient detail
• Condenser design — superior sensitivity and frequency resolution compared to dynamic alternatives
• Requires 48V phantom power — compatible with all professional mixing consoles and audio interfaces
• High SPL handling — handles up to 146 dB SPL, no distortion at high kick drum volumes
• Low-profile flat body — sits flush inside the drum shell without interfering with beater travel
• Integrated stand adapter — flexible positioning options inside and outside the drum

Ideal For

• Kick drum (internal placement)
• Bass guitar amplifier cabinets
• Upright bass and low brass instruments
• Any bass-heavy source requiring extended low-frequency detail

Place it inside the shell, engage phantom power, and experience the difference a condenser makes on the low end. The E 901 captures the punch, the bloom, and the body — everything that makes a great kick drum sound great.
