@mijostyn I understand why you would be surprised about reliability. I'm not talking about cheep speakers with amps in them, not at all. I'm talking about what practically all professionals are using in concerts and more and more in studios. When the amp is designed with the driver in mind the end result is a perfect match in impedance and power handling the drivers will last much longer. Also when the amp is directly connected to the driver the driver is dampened perfectly the voice coil will extend and rebound according to the amp, this is only a few reasons why powered speakers are more reliable, do you think live concert companies would use these speakers if they were unreliable. Nope. Also there is the added value of not worrying about speaker cables and saving the cost of the crossover designed with speaker level components not line lever as they should be designed.
