Maggie 3.6 owners -- please help

At 3 feet from the front wall you're not going to be hearing their full potential, but that doesn't mean they're not going to sound great.
You'll need to do some basic treatment to the wall behind the speakers, perhaps some diffuser panels to help give you some of the stage depth that you'll be compromising with the 3' setup.
The sweetspot is quite narrow with the 3.6's, but moving slightly out of the sweetspot doesn't compromise the sound too much. For critical listening you'll have an optimum spot that's perhaps less than a foot wide, but for more casual listening you'll have a lot of enjoyment even sitting off to the side of the speakers.

Remember that these speakers have fuses for the panels and the ribbon tweeter, so you'll need lots of good clean power to avoid clipping and fuse blowing. I know your Innersounds are pretty demanding, but I think the 3.6's are even more so. Don't even think about anything under 600 watts if you listen at fairly loud levels and your room is of average or greater proportions.

When you get all the pieces in place, the 3.6's can be a wonderful speaker.

Slipknot,

I had my 3.6's at 68" for a while then was able to bring them out to around 90". It's a great improvement in stage depth and the bass has cleaned up a little too. If you can get away with it try it.

Also, if you have some foam around or something like a 2'x 2' acoustic foam panel, put it behind your speaker with one side on top of the XO box and touching the back of the speaker, and elevate the other side around 10"-12"
If you have the panels handy it'll take two minutes. You can also try it with a sheet of 2x2 cardboard if you don't have the foam.
Listen for better transparency, a wider/deeper soundstage and slightly better imaging. Adjusting the angle of the foam panel changes the tonal balance just a tad....the optimum angle depends on the height of your ceiling and the distance from the front wall, so you may need to mess with it a bit.
