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 exact same instant.
• Maximises phase coherence for 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 aluminium 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 maximise the listening “sweet spot.”

3-Way Crossover Design with Vertical Tweeter Midrange Array

• Uncompromising 3-Way crossover with premium components seamlessly blends driver output. Subtle musical details rendered with breathtaking clarity.Massive dynamics radiate with weight and control from the highest to lowest octaves.
• Precisely tuned crossover frequencies and slopes between tweeter, midrange, and woofers result in truthful phase coherency and a precise, robust soundstage.
• Enhances on- and off-axis frequency response ensuring transparency and clear vocals at every listening position. Largest “sweet spot” possible.

Glass Fibre Composite Midrange Driver and Woofers

• Superb stiffness to mass ratio conveys stunning dynamics with flawless tonal accuracy throughout the middle octaves where most sound is present.
• Rich, effortless bass from composite glass-fibre cone with custom surround for peak sensitivity and excursion.

Unrelenting Attention to Detail

• Acoustically tuned enclosure optimises 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 aluminium-alloy baskets ensure precise alignment of critical components and maximise thermal dissipation.
• Chamfered front baffle minimises edge diffraction for optimal off-axis frequency response.
• Neodymium magnetic grilles
• Stunning Piano Gloss Black, Piano Gloss White, and Black Oak Veneer Finish

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.
• Vertically Aligned Tweeter-Midrange array creates perfect on and off-axis frequency response and blending for clear vocals and the largest possible “Sweet Spot” ensuring transparency and clear vocals at every listening position.
• Dual 6.5” woofers drive deep, accurate bass for the most demanding centre-channel content.
• 4.5” midrange driver in a dedicated acoustic-suspension sub-enclosure ensures pristine midrange output and blending with woofers and tweeter.
• 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-optimised ¾” (18mm) cabinet construction, extensive bracing, and acoustic insulation eliminate acoustic and structural resonances, ensuring an inert enclosure and an uncoloured response, even at the highest drive levels.
