I have been running a pair of these with Pyle PTA 1000 amps and they sound great. Provide enough oooomph for what I am doing which includes playing music at friend's parties and backyard theater. Surround sound in your back yard with 5,000 watts (2 PTA 1000's and a 3000 watt mixer amp) really kicks ass. These units are lightweight and easy to carry around. The build quality is sturdy. Flexible hook ups too. Great buy especially at this price.
