I do sound reinforcement for a variety of bands as well as DJ. These speakers fill the bill in every aspect. They have plenty of power with headroom to spare. Clear sound with bore bottom end than I expected. At 60lbs there are a bit heavy but this is what you need for the power you get out of them. Never expected this quality sound and power from a 30-40 lb speaker, that is just unrealistic. These are built to last and I should be using them for years to come.
