I caught one whiff of an Audacity using computer audio situation above. I'll confess, I use Audacity in two situations where voice-over material is being done for broadcast. It's free and it's full of features. Mostly features that the typical user does not understand and plays with.
In that situation forget the speakers - go exclusively with a really good pair of 'phones. To each their own on that! I mostly use AKGs but there are arguments to be made for many other brands. Remember now, voice-over is NOT music.
For studios where there is the occasional music recording I go with Adobe Audition and, for open monitoring stick with the JBL speakers I bought 20+ years ago. And yes, both the control room and studio itself were very thoughtfully "treated" - each quite differently. It may be my personal quirk but I never allow "talent" to listen to their work in the stdudio; rather bring them into the oversized control room where the monitors and room were considered together in design and construction. My "secret weapon" is kept in a separate room; the H-K amp loaded with 50L6s and re-capped about every fourth year.
