We were in a similar position and our soundman (John) bought a pair of Yamaha DXR 15s (mk2). Very similar stats to the RCF 935 apart from the wattage rating which is roughly double on the RCFs, but they're bi-amped which is possibly the reason for that figure, same SPL figures.
We found they were excellent for average pub gigs, he's kept the subs for bigger gigs but due to Covid happening not long after getting them we haven't tried them in a larger setting, so they might be fine.
Obviously a different speaker to the RCF but the Yamaha definitely coped fine with the whole band through them (drums/bass/electric guitar/acoustic 12 string/vocals).
At the first gig where we tried them, John was nervous (he gets that way) so I said I'd bring my amp and set it up but keep the volume off, then if the Yamahas didn't cope I could just turn it up. When I got there he'd also set up the subs in case (as I said, he gets panicky).
Anyway towards the end he brings a punter up on stage behind me. Afterwards I ask who he was. He was someone in a another band who had commented to our John what a great sound we had, best he'd heard for a long time. John had told him it was all through the tops, no subs or backline. He had to show him my volume was completely off for him to believe it was all out of the Yamaha DXRs.
As I said, different, but comparable speakers, so might be of help, and going by popularity and specs, I'd guess the RCFs would be even better.
