Amaizing monitors for the money

They sound very natural and pleasant. You'll need an amplifier for it but they could be the only monitor you ever need to buy. A pity that they are not being produced anymore. I use them as second monitors in my living room for general music listening and I double check material mixed/mastered on my other monitors.
