I can't speak for the LD, but I can for the 8.2s. They are easy enough for me to lift to poles and are extremely powerful and detailed. I like the digital presets in the back. I put mine on poles, in stereo and set it on LIVE/NO SUB. It puts just the right amount of bass from the speakers. To me, they are like studio monitors, so clean.
