There are plenty of reviews that praise this box (cope), and explain the benefits and applications closer. However, I would like to single out an additional aspect, namely the mobile use. We have (a part of the hall) with 4 Control Ones (and, admittedly, a subwoofer ;-) in very good quality and more sonication an entire gym as sufficient volume for a Dance Worshop on weekends. Class in these boxes for this is of course the small size (4 pieces in a backpack worked great), but also the plastic housing, which is shock-resistant enough to acknowledge not every on-corners directly with Macke in the box. I use 2 of these boxes in a little sacrilegious manner, namely once fired as mono speaker in my workshop, where they -with 150 W RMS - clear and vivid airs and is loud enough that you could ärgen the neighbors (I never do; -) The second is connected as Tweeter spare the clock radio and plays loud there at Mini-wattage enough. Head and shoulders above a 5cm-0.25W Tweeter anyway.
Conclusion: In excellent price-performance, compact box, which can be used very flexibly. Five Stars *****
