In any case, even nine 1st order caps are insufficient to derive a complete set of 2nd order spherical harmonics. Micheal Gerzon wrote about it as early as 1973.
Right I believe you need 12 capsules for "true" 360, full 2nd order ambisonics. These 8 capsule mics are 2nd Order in the horizontal plane and truly do improve spatialization & pattern decoding vs 4 capsule mics. Since there is no capsule facing directly up there is no good way to create the "R" component.
