Query: what's not said in a product description

I've bought more than a few pairs of in ceiling round speakers. For my application, I don't buy the most expensive.Though this was the first pair where I had to solder to make the connection. a little bit of a hassle when dangling from a ceiling.I've bought others in the same price range that had the spring clamping.
