Has anyone used these? Pro's or cons? Any issues with sound?[Link: nextlevelacoustics.com]

I have used the Leon but one thing I don't like about the Leon is that the enclosure itself is not the full width of the TV, Just the grill. So if the TV is positioned where you can see the sides when walking in the room, it isn't aesthetically pleasing. The Next Level Elite has the enclosure that goes the full width and has the cutouts needed for Sony and Samsung and the ends appear tapered to more match the TV sides.
