Thanks for the input.
yes, small stages are the norm. On a bigger one, well enough to have a monitor wedge and room for my cab, I can stack my two BBII’s and enjoy that for a bit!
In one of the bands I worked with, we used IEM’s for around 15 years, so adopted quite early, but the unit I’m with now will likely not go down that route. That said, we’re using an X32 as two could do it relatively easy. For monitoring four of us use the TC Helicon monitors, which is Ok for vocals, acoustic, bit of keys and guitar.
Tilting would seem to be the answer. If I could get a monitor that would sound really good (maybe RCF 7 series or similar), that maybe OK, but heavier than a BBII I’d guess.
