I don't quite understand all the arguments that the 228's would be "too big" for the room, then saying the 226's with a Sub or two would be a better fit. If the issue is loading the room with too much sound pressure or low frequency, than using a sub puts you back in the same situation of being "too big". I understand the arguments that multiple subs can help with room nodes, but it also makes setup more complicated. Plus, it greatly compounds the placement issues, in a room that is already floor space limited. I think the decision comes down to whether the OP can live happily with the limited low frequency of the 226's (which may be enough). If so, run with them. If however, he really wants deeper low frequencies than get the 228's, install some acoustic treatment and use DCR to help tame the LF room node you will have. With DCR cutting the peaks off the LF, I think you would be very happy with the bass response of just the stereo pair of 228's. Realize that both the 226 & 228 will have lower/stronger in-room response then the anechoic measurements suggest. Also, DCR will be required if you go the sub route, as well.
