These are some of the more expensive Behringer speakers, and not the cheap stuff they also make. I have bought 6 of these, and they are used almost every day. They are mounted on the walls in large rooms and are never moved around. If I was to move them around all the time I would buy something lighter. They are very sturdy, but big and kind of heavy. To me the main thing (beside price) is the sound and they did not disappoint. They sound really good! The sound much better that the (cheap-ish) JBL speakers they replaced. They also pack more bass that the Sx300 I use for portability.
Some might consider these speakers bad because they see the yellow triangle and immediately thinks cheap. These speakers are cheap, but they are not the cheapest. And you get A LOT more if you're willing to go from the cheapest to this! You do pay about twice as much, but you'll thank yourself later. These will not need to be upgraded in 6 months time!
