Yes, sure. I wrote about it quite a lot at my website. In fact most of the large Wilsons that I heard where driven by ML2s...

Yes, the ide do not let large Wilson's to go down let's say 40 cycles is probably what I would do if I own those speakers.. I would probably plug the port, and if necessary change the base driver. My point is that you need to be absolutely insane if you go for Wilson's expense and to do to experiment how to get the sounds that you want outside of what Wilson offers. Did you see any person out there whoever tried to work with a large Wilson base? I didn't. Also, do not discard Wilson and they are not stupid and they know what they do. They do not sell sound they sell products. Pay attention how they position their subwoofers. None of them are sealed, instead they are ported and tune to use at the bottom of full range large Wilson speakers. Soon a or later or ported designs sounds the same producing absolutely identical port noise. I was listening yesterday a guy demonstrate please play back at YouTube and he was playing third movement of Tchaikovsky six. She use vintage large JBL and all double bass play literally the same note. In my book it is extremely annoying. 

Now, if you have large Wilson's and drive it with old ml2, and you are willing to discard anything that come from Wilson's under 40 cycles then you are in very good shape. Now you need to find a solution and it might be only infinite Buffle or sealed topology, that will do lower base. Then you need to find amplification and crossivering solution for this. If I were in those shoes and need it ready to go product then I will look for Dunlavy TWS-6 product or something similar. Obviously to drive those monsters would be a problem and if you insist to stay in Lamm wold then M1.1 might be a good choice to start. Nowadays nobody produce those solutions out of box and there's a reason for this as the people who do it seriously understands that it is very specific to the any given room and there is no way to abstract it to are ready to go product. Again you can use anything of the shelf to compliment Wilson's at the bottom but whatever I seen so far would not be and the level of large Wilson/ML2 midrange combination.

Unfortunately anything good person that I've seen who have large Wilsons so devoted to the products and never pursue any personal objectives, or even have any.
