The combination of hi-res audio certification, Dolby Atmos & DTS:X compatibility, 1″ tweeter and 6.5″ woofer plus Power Port technology creates an immersive listening experience that is sure to please any audiophile.

The curved cabinet design ensures superior acoustic dispersion for maximum sound quality while ensuring minimal reflections off nearby walls or surfaces.

The signature sonic character of these speakers comes from its one-inch silk/polymer dome tweeters which offer crisp highs and accurate midranges due to perfectly matched components that ensure excellent transient response, smooth frequency response and low distortion levels even at extreme volume levels.

The PowerPort bass venting system has also been added to deliver deep, effortless bass without distortion or port noise while still maintaining tight control over the drivers’ movements – this helps create a more three-dimensional soundstage in comparison to other bookshelf speakers of similar size.
