I recently had to temporarily move two play 1s to the floor (carpeted) while a room is being redone ... I turned them on expecting it to sound poorly... it was ok... I ran Trueplay... and honestly they seem to sound great... better than before when they were closer to ear level.
This goes against everything I know and would expect. Have I just not experienced it enough with a diverse range and nuanced ear? These Play 1s appear to be more full and robust sounding... as if they were play 5s.
The only thing I have noticed so far is that volume has to be a little higher to fill the space.
