Why Do Audio Engineers Use Different Speakers?

Another way of asking your question is: Why aren't powered speakers popular with audiophiles? Simple, they'd be "stuck" with one amplifier. The thing that drives this hobby (and keeps people employed) is the constant changing, upgrading and experimenting.

Recording engineers need speakers that are accurate. They don't place a premium on imaging and soundstage - just that the speaker is flat enough so it's easy to compensate for different frequencies. Also, their speakers have to reside and perform in a cramped environment so they need to minimize wherever possible. Imagine setting up all your seperates in your bathroom - that's about the workspace of a control room.

I think you will find that recording engineers spend a lot of time adjusting the presentation of the soundstage (left/right and forward/back and tight focussed image/distributed or broad image...track(s) for each instrument are treated differently to create a desired presentation. Don't underestimate the imaging capabilities of studio gear as it can be equally good and bear in mind that all conventional box speakers suffer from edge diffraction at the baffle edges whilst "in wall" speakers completely eliminate this detrimental affect to the soundstage...

The answers to my question have been most enlightening. Thank you.
Now let me put a twist on my original question:
Why Don't Audio Engineers Use Expensive Cables?

I suggested to my audiophile friend that Audio Engineers do not use the expensive cables found in so many audiophile systems. His response:
"Au contraire! The high end remastering studios (not the run-of-the-mill giant studios) use high-end cables, power cords and power conditioners."

Does anyone personally know if Audio Engineers use high-end cables, power cords and power conditioners?

Are there any Audio Engineers out there who might be willing to offer an opinion?

There are audio engineers who believe that audio cables make a huge difference just as there are audiophiles who share the same conviction.

Phil Traynor, the guitar engineer and main gear guy for David Gilmour, likes Van Den Hul cable, and has even rewired the ATC's on Astoria using this cable. He used around 23 Km of Van den Hul. Pink Floyd has used this "Astoria" studio for recording as did David on lhis last album and so have many others.

gentlemen:

i visited a recording studio in brooklyn, ny, several years ago. i witnessed a recording , and listened to the recording being played through monitor speakers.

the result: irritation without representation. i would not want to own one. i am not convinced of its flat frequency response. possibly the problem wa the rest of the components, or the recording itself.
