Dont know if you all say this, but many people have been asking and they listened.
Kevin from DIY Cable about the Anarchy mids and found out that he has a 4 ohm version designed. He has not been able to get enough orders to make a production run, but he is trying to give it a go. He needs 150 drivers preordered, a tall task I know but hopefully between all the car and other sites we can get it done. Here is the link:

If you can deal with the depth, I have not heard one bad thing about this midbass.
