Which speakers have the biggest soundstage

Soundstage is a function of the acoustical interaction between the speakers' dispersion, room reflections and placement.

I have found that dipole or omnidirectional speakers provide the biggest soundstage. Front wall to speaker distance affects the depth—minimum 3 feet, preferably around 4-5 feet. Pulling your speakers out from the front wall also increases the ratio of direct to reflected sound, a secondary benefit.

Ojgalli, Speakers, dispersion, room reflections and placement mean nothing without the proper electronics.

Amplifiers, preamps and source components play a huge role in the presentation.

Ojgalli is right but there is even more to say. Soundstage is not a function of the speaker alone. Setup is critical of course. Monoblock amplification has given me a bigger soundstage, and so has conditioning the AC power.

No contest, JBL Everest.

hmmm...HUGE soundstage but NOTHING else. Sounds like the Bose 901s to me.
