I received a phone call from a recruiter two days after applying online. She scheduled two phone interviews with two hiring managers. They asked me about my CV and my projects related to the job. Everything went well in the phone interviews, and they invited me for an on-site interview.

However, during the on-site interview, everything went poorly. One of the managers started asking me behavioral questions and began using swear words. I was very shocked. I tried to remain calm and answer his questions to the best of my ability, but he continued to worsen the situation. After 30 minutes, I finally broke and became very defensive, and it became ugly. They acted as if my PhD was worth nothing and that I was there purely by luck. They suggested they could do a better job than me, even though some of them only had bachelor's degrees.

Draw a speaker without its housing, with as much detail as possible.

What is the frequency response of this speaker?

What would happen to the frequency response if you put the speaker in a housing?
