The Audix D4 Bass Drum Microphone will give your music a propulsive kick in the low end. The Audix D4 utilizes a capsule specially designed to capture high SPL instruments with extended frequencies below 100 Hz. By using a sub-impulse technology that samples sounds at a rate higher than other mics, the D4 captures a truer image of the original sound than previous generation kick drum mics - this mic is flat down to 63 Hz, with a slight bump in response at 80 Hz, and a gentle roll off below 40 Hz. From 80 Hz up to 1k, the D4 is extremely linear. The Audix D4 bass drum mic comes with a carry pouch and a mic clip.
