Robert, it's no joke what 67 and AMS are saying about the EV speakers. I had a Boogie once that had the Mesa-branded EV in it and it seriously smoked anything else I have ever tried for keeping its cool at absurd volume and filling a room with a single speaker (had a Fane in a Laney amp once that came close but not quite).
They are heavy. They are expensive. But they are worth the cost and effort if you really want to move some air effortlessly. One of these literally is worth 2 or more of something else and they are indestructible. You could move to a 1x12 cab with one of these things.
Caveat: they are not my favorite
sounding speakers, but that's subjective. For volume nothing can touch them
