I used the Sumiko Masterset method with some small Thiels (CS1.6) and got a very wide sweet spot, even beyond the width of the speakers. It’s useless for the Naim NBLs I use at the moment as they’re designed for back against the wall placement, 5.5cm in my current room. I can still get a wide image but not as wide as with the Thiels, though it goes deeper into the wall.
If my next room permits I’d like to give Omnis a go, Duevel Bella Lunas are available locally.
