I tested the speakers against my original 4 Ohm speakers before installing them in the package shelf and I am glad I did. Even though my original speakers are probably 40+ years old and showing their age with a few cracks in the paper areas they still sounded better than these new ones. My originals are Delco. This company is great to deal with and the shipping and packaging was as good as it gets. And, although the speakers look great, I wish they had the rich sound of my originals. I will keep the speakers for bench use.
