I found the sweet spot but it's 5ft off the floor

Rac,
Maggies are shipped with tilting spacers. IF the speakers in question have the little nylong spacers installed on the bottom screws of the stands, that tips 'em back. Some owners like them tipped back, others like myself, go with straight up/dn.

In general, I've never heard of tilting them forward. You will start getting floor reflection problems, which depending on ceiling height and IF they are indeed tilted back, may actually be the issue.....ceiling bounce.

Relative to set-up, my room is smallish. It's 11'x14' with an 8 foot ceiling.
It will be somewhat of a challenge to give the speakers a 5 foot breather from the wall - but I'll try. I have hardwood floors with an area rug in the middle. The walls are not dampened - just normal walls with a few paintings hanging.
The speakers are currently straight. I tilted them forward last night by about 5 degrees but I did not notice any difference; the sweet spot was still 5 feet off the floor. Also, the sweet spot is very wide/long at this height; whether I was 3 feet or 10 feet away from the speakers, the sound was outstanding 5 feet off the floor.
Let me know if you need more information.

Boy, you are really in luck. I have a life guard seat that was used at a pool. It puts you five feet up, where you can survey your domain. Cost? Free if you come and get it. It is in Timbuktu, nothing but desert here. So, hurry before the native carry it off.

Have you tried a L/R swap or tweeters in/out or ANY modified setup.
Some of the folks over at Audio Asylum / planar division may be able to help.

A few over there put the speakers EDGE ON to the listener, sitting in the side null point and relying on reflected sound. The claims are pretty ambitious.

How much toe are you using right now? Are the speakers IN PHASE? Please check 2x! Swap one +- to be sure. Are BOTH fuses OK? Pull 'em and check with a meter. 4A fuses sometimes pop and still look OK.

Since I'm not there, unless you are local, in which case a housecall will cost a beer, you're going to have to mess with it until you get it. At some point, IGNORE THE DIRECTIONS and just try anything. At some point, it'll click.

BTW, 11x14 is an awful small space for Maggies. This may be the 'root' cause of your issue.

I would take a little time and see if the soundstage height grows on you. Many people with box speakers wish they could get the soundstage height up and Maggie owners are often happy that finally they have found a speaker with a realistic sound stage height and size.
