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

The sub was probably set at too high a level and/or the low pass filter set too high.

In other words set for too much bass which obscures the rest.

Not uncommon for folks to set their subs too high.

If suspended plywood floors that will also muddy the bass and obscure detail. Try placing sub on an isolating platform if so like Auralex Subdude.

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.
