I had four Nemesis by Eden N210RS cabs and liked them, until two of them were stolen. That model was discontinued, so I replaced them with two EX210N cabs. Glad I did. Very slightly smaller, MUCH lighter, very slightly less loud at a given setting (I did a direct A/B listening test with them against my two remaining N210RS cabs), but I like their their sound a little better if anything (though the difference in sound is not very much.) At 59, my back has finally started to go, but these things are almost feather-weight. I use one GK MB500 into two EX210Ns, am playing in a pretty loud blues-rock band, and have no sense that I'm pushing the rig at all. I use two GK MB500s and all four cabs for outdoors (or huge stages) and I it's PLENTY. One MB 500 into just one EX210N is more than enough for rehearsal with the same loud band in the garage.
