Conclusion: I bought this set of small speakers to use as the rear speakers in a Mazda Miata which came without those speakers. These speakers were the correct size to fit in the very constrained space behind the seats and were fitted onto a structure mounted bracket purchased from Mazda.

Conclusion: I purchased these speakers to replace the original front dash speakers in my '86 Buick T Type. They work fine and I am pleased with how they sound. The only thing that I need to mention is that I had to mount them under the dash panel instead of on top like the originals.
Conclusion: I added this speaker to finish my mids and highs. I only needed 1 because I'm using the factory head unit to run the mids and highs and my "premium" factory setup had a single 3 1/2 speaker on the dash I guess as a center channel speaker.
