I'm not sure what you're disagreeing with.... My conclusion is that you need subs if playing bass through monitors. I couldn't see how Scott could play bass through a 12 inch monitor without wrecking it. I tried with a JBL powered EON 15 inch, which even at very low volume didn't like it one bit.
I've owned and used Gen 1 EON and Gen 3 EON speakers... and I am extremely negative in opinion of them.
The RCF and CLR are not ideal for monitoring bass; but they do the job relatively well enough for me that I've done gigs with them both in that capacity and the experience was fine. Perfect? No. Ideal? No. Preferable to a real bass rig? No. But satisfactory. (*I really only infrequently sub on bass out of necessity; it's not something I do often or pursue). I do not consider myself a bass player of any stature - I am a full blown fill-in hamfisted bassist at best.
I will personally attest to the fact, IMHO, that either the RCF NX 12SMA or CLR will perform better than ANY JBL EON at ANY task other than costing less. Just my opinion; but man... I disliked the EON experience and owning/using them was a very unhappy period for me in terms of FRFR. I mainly used the EON's at the time to do acoustic guitar and felt the Gen3 version was a more practical (ie. portable, logistical) solution compared to the Fishman Loudbox and SWR Blonde and Strawberry Blonde acoustic amps I was using for that task... but I was never very happy with the EON's for electric guitar FRFR duties.
