I use the powered JBL 15 EONs. It is a wonderful speaker. It is about 35 lbs, I think.
It's versatility is amazing. It has one balanced XLR input and two unbalanced 1/4" inputs. Each with independent volume controls. It also has bass and treble EQ controls. There is a balanced XLR output that you can use to link EONs together.
I have two of these speakers and at some rehearsals and smaller venues I set both up on stands and I can run a mic, my drums, and a keyboard into the speaker without a separate board and it sounds great! I've even ran bass guitar direct to the speakers with nice results.
When I play musicals and chorus shows I use one on a stand that faces me and the rest of the musicians and it is used as a monitor.
Sometimes when I play with my rock band for rehearsal I put in-ear monitor headphones in and plug the drums into the JBLs and the bass player and guitar player use them as monitors for the drums. Since each speaker has independent volume controls they can turn the drums up as loud or soft as they want!
Digital drums are great!!!
