With my Def 4s I worked them around quite a bit to optimize . Ended up on Sistrum Apprentice Stands and it took a few weeks, but dialed in they just really satisfy me. I think the gap ends up at about 3".
Every room is different but with the down firing woofer you will find them very sensitive to the back wall/side wall distance. I was able to get some one note bass removed from my room by positioning them 22" from the back wall and 43" from the side walls. These speakers will disappear if you place them correctly.
Probably moved them around every three or four days for a year, bought the Sistrums, then hit the sweet spot and haven't touched them for months.
Good luck. For me it was well worth all the effort.
