Acoustically Centered Time Alignment Cabinet Architecture
Curved front baffle aligns the sonic emanation point of all drivers on a vertical plane ensuring sound from each driver reaches your ears at the exact same instant.

Maximizes phase coherence for more convincing and immersive soundstage with pinpoint accuracy and imaging.

Midrange drivers and woofers positioned above and below the tweeter allow for seamless crossover blending to create an idealized “point-source” where sound flows from a single point in front of the speaker to optimize dispersion characteristics.

Diamond Coated Aluminum Dome Tweeter
Through a process called Vapor Deposition, 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 the listening “sweet spot.”

Quad 6.5” Glass-Fiber Woofers in Force-Balanced Array
Dual opposing active woofers on the top and bottom of the cabinet render effortless low frequency response while addressing room modes. Deep, authoritative bass is evenly spread throughout the listening area.

Mechanical energy from each front-firing woofer is equaled inside the cabinet by the rear-firing woofer eliminating mechanical coloration for pure, accurate low frequencies at any playback level.

Dual 4.5" Glass Fiber Composite Midrange Drivers
Superb stiffness to mass ratio on dual driver array renders stunning dynamics with flawless tonal accuracy.
