To me that does not look like the same woofer that M&K is using, if you look close it is several differences.
And I'm not sure M&K are out of business.
The thinks I've heard is that they are going to go on, but without Ken Kreisel. possibly with another brand name. According to what I have heard Ken has not been very easy to work with the last couple of years, and is now forced out of the company. By who I don't know. Hard to beleve that the European distrubitor in Denmark would just buy counterfit stuff of the Chinese factory.
Here in Sweden it's no problems what so ever with delivery problems, or things out of stock, even with the S150 system. Seems like the dealers have a steady supply. But according to my "source", Ken has control over the website at this time.
Well, I hope all speculations as my own above can be put to an end and we all can get to know what really happend.
