The new Q1's seem to be getting good reviews. One thread suggested buying three sets and using three as fronts and two for the rears and saving one or using it in a 6.1 setup. To use one as a centre surely would mean mounting it on its side. Would you get a good performance using it like this? What other centre designed for the purpose would best match the Q1 's? and would it be better than a side mounted Q1?. Finally would they go tight to a rear wall only a few cm's behind the settee listening position?
