Built for the Bottom End
The D4 is a dynamic instrument microphone built for low-frequency sources. Designed and precision-machined by Audix in the USA, it pairs a hypercardioid pickup pattern with a Very Low Mass (VLM) Type D capsule tuned for extended bass response and a natural, punchy tone. Sweetwater audio engineers reach for the D4 when miking floor toms, bass cabs, and percussion such as djembe and cajon, where the 20dB+ off-axis rejection keeps bleed from other instruments out of its channel. They also laud the D4's 40Hz–18kHz frequency response and 144dB max SPL as ideal for low-register wind and brass instruments like baritone sax, bass clarinet, and trombone. Structurally, the D4's machined aluminum body, black anodized finish, and steel mesh grille offer steadfast protection night after night, while its transformerless, low-impedance, balanced XLR output stays quiet even on long cable runs. Rugged, versatile, and built for the low end, the Audix D4 ticks all the boxes.
