Steve,
After toying with a whole array of monitors for mixing/mastering, I've settled on these.
Go ahead, laugh - everyone else does...

No longer in production, but available used or as "new old stock" here and there...

Just be sure to experiment with the subwoofer placement to get a mix of frequencies that suits your ear. I have the sub on the floor, 6" from a wall and 5 ft. from my cranium - the satellite speakers are about 24" apart, at ear height, and about 18" from the old noggin. Works for me...


just looking for clues...
Oren.
