I'm a big fan of hi-fi speakers...
"Studio monitors" as we call them now is hardly more than a buzzword... 90% of the time, they're simply short throw, low dispersion, dell sounding boxes that are meant to sound "decent" from a yard away.
The plus side - They take much of the room out of the equation.
The minus side - They sound like crap (honestly, does anyone here actually enjoy listening to great recordings on their nearfields? Hello? Anyone? Testing, is this thing on?
Yeah - I didn't think so...
Older "studio monitors" were really great loudspeakers - Big, overbearing, wonderfully colored sounding (GOOD sounding) boxes that were essentially really, really wonderful hi-fi speakers on steroids. Wonderful to listen to, wonderful to work with. But the room had to be worthy of them. And you had to LEARN to work with them, and the room.
Me? I've got my mastering speakers, but I also have a set of original Wharfedale Diamond 8.2's. I'll mix through those before I mix through almost anything that say "studio monitor" on the box. Because they sound good. Not "plain" or "flat" or "surgical" or "sterile" - Good.
YMMV, IMHO, yada, yada, etc., etc.
