I have used these speakers for the past 3 years for everything from small indoor venues to outdoor events and they are great and trouble free! I have never had one problem at all with these speakers, they are a great deal and have great sound! I wouldn't use anything else. They are a bit heavy but they are very durable and I have taken mine all over and set them up and they look just as good and sound like they did the day I purchased them. If you're looking for a great sounding speaker that doesn't break the bank these would be the best.
