Why Do Audio Engineers Use Different Speakers?


I gather that audio engineers generally use different speakers than audiophiles. I hear they tend to use smaller self-powered speakers the majority of the time.

Other than the appearance of the box and the smaller room size they are likely to be in, why wouldn't an audiophiles want to use the same speaker?

Below is a link to Steve Hoffman's equipment. He is (in my opinion) the best engineer in the business today.

Look at the wide range of speakers and equipment he enjoys.

Steve Hoffman certainly has some fine audio gear.
But are his speaker choices typical for most engineers?

Am I wrong when I write "I hear they tend to use smaller self-powered speakers the majority of the time."?
The same reason nobody drives an F1 car down the interstate. For the engineer the speaker is a precision tool used to to manufacture a product. Unike the audiophile listening pleasure does not enter into the equation.
