These days the signal source and analysis functions are generally
performed using a PC with a high quality sound card in it.

But the problem is that we shouldn't use a crappy mic and the analog
input of the soundcard. Any way around it?

Non-crappy mics for testing speakers are pretty easy and cheap - Behringer
ECM-8000.
You need a good mic preamp - One option are the mic preamps in a Behringer
UB802 mixer.
Sound card in your PC might be fine, or to be sure try a Turtle Beach Santa
Cruz.
