Same as the B652, but updated with an AMT tweeter with treble extension to 40KHz.
Ranked in these QuestionsQuestion Ranking
Pro AMT for treble
The AMT replaces the conventional diaphragm tweeter. The AMT doesn't suffer from many of the response issues of diaphragm tweeters, so it plays up to 40KHz with a very clean transient response and smooth detail.
Pro Woofer is well controlled for this price range
Like the plain B652, the woofer only has one major spectral peak near 3KHz. Although none would be preferable, the B652 woofer has better clarity than many due to its fast decay time.
Con Brilliant treble
The treble is set very bright for this speaker.
Con Simple crossover
There is just a resistor and capacitor in series with the tweeter, and the woofer handles a significant portion of the mids. A better crossover would control the woofer peak in the mids.
