Driving 4 ohm speakers

If worried,wire them in series>> Out to L200 "+",out the "-" to the L300 "+","-" back to the Arcam.This should present the Arcam with a 6-8 ohm load.

I have no knowledge of how well the Arcam would handle a two ohm load. But I want to point out that while putting either a resistor in series or the two speakers in series will result in a functioning setup, it is not a recipe for quality sound. In either case bass damping goes out the window. And in the case of the two speakers in series, if their impedance vs. frequency curves are not identical, frequency response irregularities will result in both speakers.

"My question is, can I drive both with this amp at low volumes? In this small space, I can't see cranking up the volume very high. Obviously, I don't want to burn out either my amp or my speakers."

Well, maybe I misunderstood the question...I didn't think the issue was one of 'high quality sound', but convenience.
Oftentimes we make decisions of either. In this case, at low volumes and for an office, I think the best, most logical solution is the switching box.
I read the question, "How can I make this happen?" Not, how will it sound?

If 'high quality sound' is not the issue, then wire up in series, Alarg's misgivings not withstanding.
