2 subs in a small room?

I recently added a REL T/5i sub to my system and have been very happy with the results.  Integration was a breeze and I am now more engaged in my music than ever.  So of course being a typical audiophile, I got to thinking if 1 sub sounds this good will 2 sound even better?  The challenge is my room.  Its very small at 9' w x 10' l x 9' h.  The back wall is about 3' high, above which it opens up to the rest of my house.  I have bass traps in this room.  Right now, using just 1 sub, my freq response from 20-1000hz is +- 2db with a -4db dip at 200hz and a +4db hump at 40hz.  Not perfect but my system still sounds amazing.

I know the general consensus is a second sub will sound better but I am concerned with the size of my room.  Will adding a second sub in such a small space over power it or will it actually help to smooth out nodes?

Thanks, she's been throwing up for almost 10 days, really nasty virus.

It is hard for me to wrap my mind around as well, as I understand it
summing 2 inputs L + R into mono creates as phase shift which translates into signal smear if you will, I assume because its low signal its a connection thing the smear happens at the inputs and has no bearing on wether the subs are playing or not. If I leave the subs off or on the improvement is there. Glad to hear you are going to add a second one this year, you will not regret it!

tboooe, I have a room that is 10' x 13' x 8'. I have two back ported LSA1 speakers on stands. I have both in corners and only about 6" from it. I have very good bass and wouldn't  think of adding a subwoofer. I have never had any success with even two of them.

My system uses the second sub so that I can use two of the same amps to drive them. I did phase align the subs with my main speakers, using a most useful tool, a yardstick.
