I did Sound for my Original Band [not a soundman; so did my homework/research]; I could never get Bass Tone I was content with, only acceptable through PA
We used IEM's/wireless and I could get CD/Studio Quality mix; helped keep us super tight and Singer loved it.
We had 2 Powered Mackie 15" with Horns and 18" EV Powered Sub.
So after a few Gigs I used my SWR Head into 4x10 Goliath Cabinet and put in middle of 2 Mackie's and lowered xover on Sub to 60hz and below and only went to board for IEM
Finally Satisfaction not just bass but whole mix out of FOH.
But with Last Band I played with [Cover] we did a Local Festival and my Bass tone from FOH by Sound team was best I ever heard it along with great tone from powered monitor in front of me.
