With Ambisonics, using three subs (arranged in a triangle) you can decode to 360° horizontal-only. Using four subs (arranged in a tetrahedron) you can decode to full-sphere. Note that, because the subs are sent only low frequencies, you can use a single-band "velocity" decoder. With a dual-band Ambisonic decoder, which also handles higher frequencies, you need more speakers than three/four.
