I have a sound guy buddy near Joshua Tree, Cochella Valley that likes his 50's. Primarily they are rentl inventory for him. One of my guitarists bought an L1 Pro8 last year. So I bought one and we ran the pir for a while. I sold mine a couple of months back - not happy with the mechanics. The column connections are kinda light and they need more meat to align properly.
I bought a pair of Yamaha DLX1K. This is the external speaker version of their Stage PAS system. Two XLR in plus Link in/out. Volume per channel, Master Vol and a one know tome control that goes from Speech, through Music to club. I dodn't need ot want the built in mixer fof the Stage PAS. Got the Ui-24r, Flow8 and XR-18 - need another mixer like a hole in my head ;-)
These are much more robustly built than the Bose. They have 12" woofers a slew of little drivers in the column. Overall they sound nice. Have a much more authoritative low end - on a few dates for my vocal trio with acoustic guitar, roland hand sonic and my EUB, I skipped the amp... We are not loud and that might not work for everybody, no question.
I landed these at under $900 per unit in a transport bag from my typical Ymh source. There is ad olly that the bag attaches to. $112 off Amazon. I just bought one and will clone it next week.
IMO - these beat the hell out of the L1 Pro8. How they stack aginst the Evolve 50 and the RCF Jvox - no idea...
