I didn't except so many great responses, very informative and lots of good ideas, thank you!
I have reached out to the manufacturers and am awaiting their response.
@blisshifi - the room is 24' x 15' with a 12' vaulted ceiling (the long ways). Then there is a kitchen to the left of the speaker, so the room is L-shaped. Drapes cover the window to the left which run pretty well the whole length of the wall. The manual says 1 - 3 feet off the back wall, so being a multi-function room, it's pretty hard to get the speakers more than 1 foot out. They are 6 1/2' apart, slightly toed in and I sit about 9 feet away. So, there is 8' feet of space behind me.
The room does suck, but acoustic treatment are expensive and lack WAF. I'd hate to spend a bunch of money on them and still have a base problem, so I like the idea of a couple of small subs, or better yet the room correction suggestion.
@erik_squires - thanks Eric, for some reason when I click on the link you provide (as with some other links here) I don't get redirected. Any tips?
