A big speaker element is useful for micing kick drums.

It was so popular in studios to use an old Yamaha ns10 speaker as a kick (bass) drum mic that now Yamaha started making and selling an “official” version.

I personally used a toy guitar amp for this purpose https://music.stoyanstefanov.com/2017/03/30/diy-sub-kick-mic...
