A very simplistic definition would be dry = unprocessed raw sound without too many effects.
wet = add desired effects like reverb, EQ, and other techniques to achieve a certain desired outcome (e.g. a rich reverberating piano sound like the one you might hear at a live recital in a good recital hall)
Which is why I said that my feeling was this was an issue with the Zimerman/Schumann recording more than an issue with the speakers.
Again, this is standard audio terminology, something that a lot of people understand approximately which is why you'll see these words being used in professional reviews of recordings and other audio related equipment. It is far more useful for most people to see the word "dry" being used to describe a recording than to look at a graph. I hope we can return this thread now to discussion about Emp Tek speakers because I'm getting tired of these trivialities. If concerns about words like "dry" being inappropriate to describe audio were legitimate, I wonder why people visit forums such as these. They should only have to look up graphs on the manufacturer's website and not rely on reviews written in English (or any other natural language) to make their decision. That is the only point I wanted to make.
If people still think all that was pointless, I'll gladly delete my review.
