I have always been wary of small woofer / subwoofer drivers with a large Xmax. Often the area of the surround is greater than that of the diaphragm. My question is: which specific part of the driver produces sound waves?
I am restricted in cabinet size and have a choice between 2 x 5" woofers or a single 6" - The diaphragm area for either scenario is the same.

Cheap, if you are in North America, https://www.diyaudio.com/community/threads/silver-flute-w14-woofers.396686/

2 x 5" drivers will have more area than a 6" from the same manufacturer's range plus there is fair chance the motor will be the same or close leading to no practical difference in the stroke. There can however be significant differences in effective cone area between what different manufacturers label 5" or 6" drivers which may be the cause for your apparently odd claim? The whole of the cone contributes to radiating sound plus approximately half the surround which will be creating no sound at it's outer radius and as much as the cone at it's inner.
Assuming similar drivers 2 x 5" is likely to be preferable for most parameters except price and possibly bass extension though bass extension with less clean SPL and inadequate cone area for clean standard levels may not be worth much. But with subs...
I am restricted on cabinet size! Maximum height is 210mm. A 10" driver in a 35 litre box is ridiculous.
You should re-check your calculations: 2 x 5" is over 39 square inches. However, this is irrelevant as driver size does not equal cone size. A 5 inch driver's diaphragm is less than 4 inches, A 6 inch driver offers less than 5 inches of cone.
@wolf_teeth & @andy19191 - thanks a bunch.
Using your suggestions: 2 x 5 = 22.68, 1 x 6 = 19.63.
