Short answer: the KEF R11 Meta for bass depth and forgiving placement, the Revel F328Be for efficiency and directivity if you can sit in its vertical window. The F328Be is quite flat on-axis with superb directivity and efficiency above 90dB, but its vertical directivity is asymmetric, so the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis. The KEF reaches an F10 of 30Hz with a dip around 1-1.2kHz.
Buy the KEF R11 Meta when the price outweighs sound quality for you, and the Revel F328Be when sound quality outweighs the price instead.
