These being £1200 a piece, I dont know how much of a loss you made. I've never been asked for a speaker less gig in 45yrs and never been paid 2 grand for a gig
It's not a criticism, Opaz Your quite entitles to spend your money as you wish. I was assuming that at the time you bought them, it was for just the 1 gig.
I understand corporate gigs pay more in general than private birthdays, and I mainly do private gigs, so to break even I would have to do about 10 gigs.
