I don't have time to post anything detailed right now, I can only say that you obviously have never heard a good car audio system, and you have not heard close to the best in home audio subwoofer systems if you consider the sunfire near the top. It will play as loud as 3 15s that are not good subs, but there are a number of 125.00-150.00 15 subs that will have more output.
There are no quality differences between JM Lab and Focal Audiom. You say there is documented differences. Prove it. I will leave it at that.
I can honestly say that you have argued with less knowledge for a longer period of time than just about any other poster I have come across.
