Usually sufficient for the acceptance dynamic types. The placement of the microphone into the bass drum sound plays a role. The distance to the skin should be 10 - 15 centimeters. The exact alignment is again a matter of taste. Please make sure when using condenser microphones, that occur in the center of the drumhead and the distortion of the strongest impulses are greatest.
