These speakers rock! They can play hard all night long and have lots of bass. They can handle long periods of high volume and are pretty cheap. The quality is good and if you add two Peavey subwoofers you have a really powerful system. I played these things at a party recently at about 700 watss each for 4 hours straight and they sounded great.Highly reccomend as an alternative to Peaveys. Much better sound. More durable to.
