Stunningly detailed and refined sound with impressive bass from a compact bookshelf speaker Composite glass-fiber cone with excellent stiffness/mass ratio for high sensitivity and pistonic behavior Chamfered front baffle and flush-mounted drivers improve on-axis and off-axis high-frequency response Hyper-rigid diamond carbon coating on an aircraft-grade aluminum dome delivers best-in-class fidelity linearity and transient response FEA-optimized cabinet construction bracing and acoustic insulation eliminate acoustic and structural resonances The Culmination of Sonic Obsession Capable of highly engaging and detailed sound with bold dynamics and bass you would expect from a much larger speaker Ultra Evolution Nano delivers audiophile sound and versatile placement options. Perfect as a stereo pair in a small to medium sized room or as front LCR or surround speaker in a home theater. Time Aligned Cabinet Geometry Curved front baffle aligns the tweeter and mid-woofer on a vertical plane ensuring sound from each driver reaches your ears at the exact same instant. Maximizing phase coherence for more convincing and immersive soundstage with pinpoint accuracy and imaging. Diamond Coated Aluminum Dome Tweeter At the forefront of audio engineering is a process called Vapor Deposition where a layer of diamond carbon is applied to the aluminum dome tweeters to vastly improve rigidity and acoustic properties. This breakthrough in material science raises the frequency response well beyond the limits of human hearing resulting in effortless airy and unveiled highs with no measurable distortion. The diamond coating also pushes low frequency extension of the tweeter deeper for more seamless blending with the midrange. Organic cell lattice tweeter diffuser protects the dome and employs semi-random pattern derived from organic cell structures to improve off-axis response and maximize listening sweet spot. 5.25" Glass Fiber Composite Mid-Woofer Superb stiffness to mass ratio renders stunning midrange dynamics with flawless tonal accuracy and deep accurate bass. Acoustically Tuned Driver Enclosures Separate acoustically tuned internal chamber for the mid-woofer optimizes separation and eliminates the potential for resonances from the enclosure resulting in pristine sound across the frequency spectrum. Unrelenting Attention to Detail Separate acoustically tuned internal chamber for the mid-woofer optimizes separation and eliminates any potential for cabinet resonances resulting in
