Inspired Design, Reference Performance.
Time Aligned Cabinet Geometry
Curved front baffle aligns the sonic emanation point of the tweeter and woofer on a vertical plane ensuring sound from each driver reaches your ears at the same instant.
Maximizes phase coherence for a more convincing and immersive soundstage with pinpoint accuracy and imaging.
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 the low-frequency extension of the tweeter deeper for more seamless blending with the midrange.
The organic cell lattice tweeter diffuser protects the dome and employs a semi-random pattern derived from organic cell structures to improve off-axis response and maximize the listening “sweet spot.”
6.5" Glass Fiber Composite Mid-Woofer
Superb stiffness to mass ratio conveys stunning dynamics with flawless tonal accuracy, and deep, accurate bass.
Unrelenting Attention to Detail
Acoustically tuned enclosure optimizes low-frequency tuning and eliminates any potential for cabinet resonances, resulting in pristine sound across the frequency spectrum.
Uncompromising 2-way crossover with premium components seamlessly blends driver output. Subtle musical details are rendered with breathtaking clarity, while massive dynamics radiate with weight and control from the highest to lowest octaves.
Precision-cast aluminum-alloy baskets ensure precise alignment of critical components and maximize thermal dissipation.
The chamfered front baffle minimizes edge diffraction for optimal off-axis frequency response.

Crossover & Cabinet Specs:
Crossover:
- 2-way crossover with premium-grade capacitors, inductors, resistors, and heavy-trace printed circuit board
- Tweeter-to-Woofer crossover: 1.8 kHz
Cabinet:
- Time-aligned cabinet geometry introduces microsecond-level time delays between the drivers, ensuring that the effective-acoustic-center of each driver is equidistant from the listener. The result is improved linearity and directionality throughout the crossover frequencies, and a more accurate soundstage.
- Chamfered front baffle and flush-mounted drivers reduce edge diffraction and improve on-axis and off-axis high-frequency response.
- Extra-thick 1” (25mm) driver baffle ensures a rigid, resonance-free mounting for all drivers.
- FEA-optimized ¾” (18mm) cabinet construction, bracing, and acoustic insulation eliminate acoustic and structural resonances, ensuring an inert enclosure and an uncolored response, even at the highest drive levels.
