Two subs in a small room....

I have read that two subs smooth out the bottom end and give a much better sound. But, what if you have a room that is just not big enough for two subs. Is it worth the effort to get two "small" subs or is there a special placement for just one sub besides the usually place, behind one tower. What about placing the sub right in the middle?

By the way, my system is in a 10 X 10 room and it is in a diagonal configuration if you can picture that.

10x10 room will tend to amplify 55Hz (1125ft/s / 20) - not ideal since many speakers have port tuned to about 30Hz and get already hump on 60Hz. Bipolar speakers cancel this effect by directing sound in both directions (canceling). Similar effect can be perhaps achieved by using two subs facing opposite directions. AFAIK sound at low frequencies is not directional. Two subs are often used to reduce room effects (peaks and valleys) and not for the amount of bass or imaging.

Magfan CDs might be but I remember that LPs were recorded mono below about 100Hz.

As for smoothness and richness it is better to get one good sub like JL Audio Fathom 113 that can auto correct for room and whole system response with microphone placed in listening position - instead of two average ones. Studies made with multiple subs usually are oriented toward theater environment to flatten peaks and valleys in whole room.
