I think egg-shell white should be offered on the QS series as well. I alsways assumed that white wasn't offered because of economies of scale issues. If the vinyl is in the shop, and it can be cut to form a Q series or even some of the others (since some might like to "hide" a white M2 in the back of a room, maybe) could be made in white as a "standard finish" as well. Just a thought.
Anyway, I'm impressed by the speaker, and consider it a decent looking alternative to a traditional in-wall speaker. I'm sure it kicks regular in-wall's asses as far as sound goes, but it is less discrete than I would have hoped.
