I use an E140 for a subwoofer and it works fine. Some day it would be great to have a few 2245's, but to be honest, with a plate amp I have this turned almost off for any music listening. I turn it up a little for home theater. For grins I have swaped out the 2226's in my mains with E140's. I think you would be ok using them. They sound very similar, and to me they seem not as tight as a 2226. Wayne might have some better insight on distortion qualities. Great buy!
