I've been playing around with these little guys the past few days and am really surprisingly impressed with these things. The mighty JBL Studio 530. I say these easily outperform the Monitor Audio Silver 3i and Sonus Faber Venere 1.5's that I had.
Luckily, there's no real difference in sound with the grills on or off, so I keep them on as these speakers are sort of ugly with the grills removed.
