How many companies make 6 Ohm woofers now? (Including dual VC 3 ohm)Names? Need to do some research. So far I have only found 2. JL and Kenwood

I am wanting to do three 10's at a 2 ohm load. If I can't find something I'll like, I'll just run 3 DVC 4 ohm 10's at 2.66 ohms. But I would rather have the 6's.

Any help would be appreciated.
