yes, it seems like quite a lot at first, but it isn't 2000 cabs really, but 2000+ IRs. Most cabs have 8-14 IRs shot with different microphones in different locations.
Most of the time you should be able to narrow it down to the type of cab and/or speaker and then it's just a matter of finding the right IR in that range of cabs.
Thanks for that perspective, very helpful indeed!
