I was wondering what 2-ohm speakers are available in 6.5" and 6"x9".

I found the Inifinity 63.7i:

and the Infinity 693.7i:

but they are relatively low powered. I have a 4-way amp that is 2-ohm stable, and wanted to get the most out of it, but it seems that there are very few full range speakers in these sizes that are 2-ohms or are DVC.

Does anyone know of any other models?
