Not using them currently, but I've used them in the past. I couldn't find anything to complain about, either. I think ARC is one of the best lineup's out there right now.
These are SMOOTHEST , most ACCURATE, BEST sounding speakers ive heard. I love how smooth these things are , its really amazing . The sets needs LOTS of power to shine, i used to use 50 to each side and it was alritht, i went to 110 to each side MUCH better. The only down side to these are that they are not for the person with 18's in the trunk. I always new they were rainbows in the inside. I think for the money they are awesom(i think they were like 300?$)
