Shure | Beta 91a | Kick Drum Condensor Microphone

What is the Beta 91A best suited to?
The primary use of the Beta 91A is kick drums. It can also be used for other low frequency applications including piano. 

What are the characteristics of the Beta 91A?
The Beta 91A is a half cardioid condenser boundary microphone. You can expect a strong low end response as it is specifically tailored for bass frequency applications, and superior attack and punch for studio quality sound even at extremely high sound pressure levels (SPL). 

What is the difference between the Beta 91A and the Beta 91?
The Beta 91A features a new and updated microphone capsule. The new capsule will result in a more natural high frequency response than the Beta 91.

Are there any other Shure Kick Drum microphones? 
The Beta 52A is a super cardioid microphone and is also suited to kick drums. With the Beta 52A you can expect even more low end.
