ok... is it the same for impulse responses of amps/cabinets?

then, if I understand correctly, these files are convoluted with the
signal... this means that the overall effect will be equivalent to a
specific equalization, or to some type of reverb...or both? 

the fact is the wiki talks about "convolution reverb", but I used to
think that amp emulation was just a matter of equalization
