I have to think Revels Salon 2's face design is far more "technically appropriate"
The Q series face plate is indeed sculpted, and unlike Revel, which have a large flat area around the drivers, the Q face plate is completely round on the horizontal axis. It is also not made out of MDF, nor any of the hardware is exposed. If you look at Revel Salon2 measurement in comparison to the S5 ( Both on Soundstage), you can see how much better the S5 is, in particular the THD measurements. BTW, the YG fall flat on their faces in that regards.
