The large level limit of the N=2 SO(2*N*) Kazama-Suzuki coset models is argued to be equivalent to the orbifold of 4*N *free fermions and bosons by the Lie group SO(2*N*)×SO(2). In particular, it is shown that the untwisted sector of the continuous orbifold accounts for a certain closed subsector of the coset theory. Furthermore, the ground states of the twisted sectors are identified with specific coset representations, and this identification is checked by various independent arguments.
