I had both an RS 4.5 and later on a 2b (which I bought from someone who worked at the factory) I can't recall if I had a bass equalizer box, but I was biamping anyway, so maybe I didn't need one ;-) Otherwise you may need it along with the jumper cables. Assuming all the drivers are OK, it could be that the connectors (which were push-on IIRC) to ALL drivers including woofers need to be cleaned with DeOxit or similar. Ditto the level controls which you can get at from inside after removing the woofers.
To get the most out of the 2b's (and the 4.5's too as a matter of fact) biamping is almost mandatory, with tubes on top and solid state for the woofs.

They might be able to provide you with a schematic for the equalizer. BTW, don't sweat the Monster Cable, at those (short) length, it really won't matter what they use as long as it's heavy enough for the power. It's the connectors and rheostats that you should check.
