What type?
I was bitten by a French horn at an early age so the infection eventually became more than a hobby
When I was very young, I heard my Grampa play a French horn and then later heard him play a French horn recording through his Heathkit mono hifi. I was fascinated how “his horn” came out of that box and then how it was stored on the black disc (record) spinning on the thing “I shall not touch” called a turntable.
Strangely, I was much less curious about him playing the horn than what was involved playing it back.
Later at age 9, I was already VERY curious about how things worked, especially related to sound.
One Sunday afternoon I was helping Grampa clean up the Church after service when I saw the Organist had just parked outside and was back to practice.
Having explored the more interesting places like the furnace room, the cavity under the pulpit, the tower where the bell used to be and organ pipe loft and such, I hurried up to the room where the extension ladder in a closet lead to the organ pipe loft.
This type of organ had a small room full of organ pipes and the volume was regulated by opening and closing louvers into the sanctuary.
Inside the pipe room, it was full blast all the time.
When she played a pedal note, I didn’t know if it should run or what, it shook my body and yet there was nothing moving.
I stood there instead of running until I felt like I had enough (a couple songs).
The only thing I could find as a kid that had that effect was stand 10 feet or so away (as an adult what I would call dangerously close) from a speeding freight train, which thankfully we had in our back yard a few times a day. Much later in life I found this feeling was something like was the term “Sublime” as it would have been used in the iron age but here applied to sound experience.
Many years later in the early 80’s I was able to develop a new type of loudspeaker / subwoofer transducer while working at a NASA contractor. My boss was a hifi buff and when version 3 sounded good enough to show him, I brought it in. He liked it and let me start some informal work on the clock and start a small speaker division.
These were called Servodrive Subwoofers and nearly all were very large speakers used in concerts and for special effects at theme parks and stuff but an off shoot of a subwoofer made for Elephant communication research called a Contrabass was a modestly successful in large home theater systems. A number of well known Hollywood types have these or had these back then but at the time the idea was pretty ridiculous to use one in a normal home.

Another rotary transducer (I didn’t invent the first one)

Since then my focus has been much less on transducers and more on high power subwoofers and Full range loudspeaker systems with the goal of making them radiate as if they were a single point in time for large scale hifi in commercial sound.
