I have the 600W/8 ohm LFSys Monaco (with 12" speaker, port and tweeter) and it has more than met the requirements of various situations without any complaint or struggle....
Small rehearsals
Large rehearsals with a 9 piece band
Pub gigs
Club/Arts Centre gigs
Theatre gigs
It is articulate, clean and punchy.... but handles plenty of low end and has excellent dispersion. Basically it can cleanly reproduce whatever you put into it... and I can also hear it clearly from over the other side of my drummer...!
It's also lightweight and neatly proportioned and one of the best gear purchases I have ever made. Customer service is excellent and personal too as it is within this community.
