I bought just one, for mono listening. I actually really like the sound :)
While it lacks the lows and the highs it's still surprisingly pleasant to listen to and not harsh like NS10. Having the sound in mono, coming from a single driver is nice and in a way it reminds me of the old, large TVs. For critical midrange, and mono compatibility check this does it for me.
The only complaint is that the production seems to go very fast, so fast that they don't even let the glue on the driver to cure. Mine came with it still fresh and sticky and the glue wasn't applied very nicely. The quick assembly is evident, but the speaker works fine, so... It's good.
I don't like the gloss finish, but that's how it's made, so I'll have to keep my fingers off it.
