Turned Off My Subwoofer ... And My Speakers Sound Great

I have my Maggie's. 7's four feet from wall eight feet apart and eleven feet from listening position and intergarated with one SVS Ultra 13 Sub and I only have room for one sub. It was a pain to get the synergy, but now I would never get ride of my Sub and lose all the musical impact a Sub can bring

Serious question.
Do you think a room the OP,s size of just 10x9x8 could handle a DBA or even two subs?

Yes. Without a doubt. The whole reason for DBA is to smooth out room modes that are created by rooms being smaller than the lowest wave lengths. Totally stands to reason that the smaller the room the worse the modes and the more the benefit of multiple subs.

I think where people get screwed up is thinking that adding subs means more and more and more bass. This is NOT the case! Each sub that is added the volume of ALL the subs is reduced. There are more subs but each sub puts out less volume. All together they add up to the right balance. Only better. Because to get that balance with one or two subs there’s always a hump or two that you have to live with in order to not have a suckout hole or drop-off. But with multiple subs the humps are almost non-existent and there is no dropout. That’s why everyone with a DBA raves about how smooth, fast, articulate and DEEP their DBA goes.

Play a bassy track. Reduce the sub output and tune the cutover to lower than you had. It should just barely add in the lower frequencies.

Yea for the most part that's true. Twice now I've visited guys homes with 4 unit DBAs and ask me to listen.  One sounded good, one  OK, WHY?
They had their mains that were good to 27 on one and 35 on the other.
Simply put, one guy, cut his mains through an active EX at 60hz and let the DBA do the rest. It was quite impressive.

The other guy with RM30s which were better monitors BY FAR than the B&Ws. Sounded like crap because he didn't cut the mains at  60 or 80.
If he would have, I know the better sounding speaker system would have been there.  It was just bloated. Needed to turn it to like 30 as a cutoff, just boomy

He wants me to show him how the other guy did it. He was there, and wouldn't ask..

The guys BI amped , bass into an Active XO, disconnect the factory XO for bass. Set the slopes, EVERYthing including correcting the surly bad bass XO with no correction and a the cut points. It's set up like a band pass. Sounds great too.

The only thing wrong with many subs in most cases is the additional expense and complexity for what you gain. I’d focus on getting one sub set up right for your sweet spot first before even considering more. That alone is hard enough to do in many cases. Then if you need to have properly tuned bass in other spots, arrays of subs to distribute the bass more evenly across the room is a solution. You don’t add more subs to get bass right in one spot. A suitable sub tuned properly is the most you need. With larger full range speakers and/or in smaller room even 1 well selected sub set up well may not add much if anything.

This is all for 2-channel music listening of course. Home theater is a different ballgame.

Having said all that I would not enjoy my relatively small and not particularly bass extended kef ls50s in my 12X12 room nearly as much without the sub. With it, there is not much to want.  The ls50s are fabulous speakers for smaller rooms within their limits.
