A reduced model for a pressure-driven subsonic combustion wave spreading through an inert porous medium (subsonic detonation) is derived. It is shown that the associated planar travelling wave solution may lose its stability assuming a galloping or spinning structure as occurs in supersonic free-space detonation. The problem of subsonic detonation is found to be dynamically akin to the problem of gasless combustion known for its rich pattern-forming dynamics.
