The box dimensions are different.
The 110HT is 16" tall, 11" wide, 8" deep. The cabinet dimensions suggest that it would be a good fit for surrounds where low profile is important.
The 110XM is 16" wide, 14" deep and 9.5" tall (as sitting on the floor).
110XM sitting on the floor:
The compression drivers are different on the 210RM and the 110HT/110XM because the 210RM is a 3 way design and the 110HT/110XM is a 2 way design.
The 210RM has a 2 way ultra high end coaxial compression driver (tweeter + mid range), and 2 10" woofers. This compression driver is top notch.
The 110HT/110XM is more value oriented. The coaxial driver is the compression driver (tweeter) mounted behind a 10" woofer.
The 210RM's compression driver probably costs 3 times vs the 110HT/110XM compression driver. 3 way designs also have much more extensive crossover network.
