I meant that when people use a speaker as a kick mic they tend to use the speaker from an NS-10.
This has been done for decades, it is neither new nor weird.
I don't know if a noisy old 15" will do the job, but a good 8" or 10" works well for kick drums or floor toms. Be sure to put some foam or other padding under them or you will get a lot of floor noise.
1) Showing or characterized by cheerfulness and lighthearted excitement; merry.
2) Bright or lively, especially in color: a gay, sunny room.
3) Given to social pleasures.
So, yeah ..... I guess using a speaker as a mic could be a gay experience.
