they work great to house items like baluns, extenders etc... Plus when paired with the Samsung QLED flat screens they are AWESOME. The TVs are soo thin because they removed all the video inputs connections (the way the old pioneer elites used to") and the processor fits right inside the box, when paired with the "No Gap" wall mount, its like a hanging piece of art. Its pretty darn nice.
