I haven't looked on the v3's but the v2 speakers have the crossovers attached to the speaker wire plate on the back of the speaker, quite easy to change(I've done it on my M22's). The bigger issue is the xover change may also require a driver change depending on how old your speaker is. Axiom had at one time early in the v3 run, mentioned they were looking at producing a "kit" for v2 owners to upgrade with, but this meant new drivers and the price for a full set of drivers & xover wasn't much less than a new speaker for M60/m80 owners.
