When purchasing I thought I was getting a pair, but the price was each so I ended up spending twice what I expected. It was worth every cent. The clarity, crispness and high decibel limit coupled with low distortion gave them incredible sound. Even without a crossover, just the supplied capacitor, coupled to a pair of head unit speaker outputs at 50 Watts each, I was very impressed. I used these tweeters on my boat, and have seen no corrosion as of yet.
