While there are generalized speeds we use, supersonic (which is the speed of sound in air) has no bearing on the classification. Due to densities, about 3100 fps is typically seen as the common threshold for a detonation. Some reactions go from one to the other as well, so it is not universal.
    I was not using Wikipedia.

    This is the definition of detonation that was taught to me:
    A detonation is classed as an explosion. It is a chemical reaction that propagates with such rapidity that the rate of advance of the reaction zone into the unreacted material exceeds the velocity of sound in the unreacted material.

    And from what I understand the deflagration/detonation threshold is 1000m/s (3200 fps) not 3100 fps but that is just semantics.
