He certainly changed speakers drastically. The QSs are particularly suited to surround duties because of their very wide dispersion, which generally fits the nature of the surround material. More direct radiating speakers, such as the M3s, can certainly be used successfully there, but it's suggested that they be given more room to "spread out" than the QSs need, say 9-10' behind the listening position. If you don't have a considerable amount of room in back, it wouldn't be the best application for them. If you can get the M3s at a very good price, you might also consider using them up front as "width" speakers.
