I am dreadfully disappointed by the quality control of this brand. 3 minutes after I opened the box, I found that the mid range speaker is turning out dry and broken sound (seems to relate to problems in the frequency separation electronics) and the tweeter of the other channel is found to be damaged. There is a protective cover on the tweeter and it can't be damaged during transportation. The only reason is that NO TESTING HAS BEEN DONE IN THE MANUFACTURING PROCESS !!!
In terms of sound, it is pure boom and tizz. The bass is uncontrolled and overwhelming. Given what I've experienced, I would recommend caution towards the brand from a quality or even product safety standpoint.

Hey Chan, it only took you 3 minutes to hook up your speakers after receiving them? Now that right there tells me you don't know what you are talking about...MB Quart speakers are fabulous. Great price, design, sound, and quality control.
