2001RB setup for Normal Operation:
The 2001RB series amplifier is configured for normal operation when you are connecting to any cabinet with a 2 conductor Speakon cable, 1/4” to 1/4” speaker cable or 1/4” to banana plug speaker cable. In this setup, the speaker cabinet is driven by the 540W amp and the 50W tweeter amplifier is not used. If you are using RBH series cabinets, the volume of the tweeter (relative to the woofer’s volume) can be adjusted using the Horn Level control of the cabinet’s internal crossover
You are using the first instance - as in the cab will only be driven the 540W amp. So in other words, make sure the amp isn't bridged, plug in your 2 conductor speakon (take the cable apart and you'll only see two cables inside) to the "left" output of the amp, and other speakon at the end of the cable to the EBS cab and you're in business.
Forget about the bridging or crossovers, you don't need them in this case.
