The positioning is quite unforgiving. The amount of tetris I've played with the layout of this room as a result of monitors is ridiculous. The Opals' lows are very touchy, and I've still got them set to 1/2 space for reasonable results in here.
Anyhow, I'm sure someone here grabbing their first monitors (or auxiliaries) will enjoy the RP5s. The funny thing is that one of my old clients moved from these same monitors to Opals in the last year and loves the change as well. Makes you wonder what you were doing for the first part of your working life.
