INSPIRED DESIGN, REFERENCE PERFORMANCE.

Acoustically Centred 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.
• Maximises 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 idealised “point-source” where sound flows from single point in front of the speaker to optimise dispersion characteristics.

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.”

Quad 5.25” Glass Fibre 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 conveys stunning dynamics with flawless tonal accuracy.

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

• Tweeter-to-Midrange crossover: 1.8 kHz
• Midrange-to-woofer crossover: 170 Hz

Cabinet

• Acoustically Centred Time Alignment architecture.
• Acoustically-centred architecture orients the mid-range and woofer arrays in rotational-symmetry around the tweeter, ensuring that low, mid, and high-frequencies emanate from the same effective point in space, creating a coherent, integrated, faithful acoustic image.
• 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.
• Quad 5.25” woofers in Force-Balanced Opposed Array energise any room with deep, accurate, evenly distributed bass, while contributing a net-zero vibration force to the cabinet and other components.
• Dual 4.5” midrange drivers share a dedicated acoustic-suspension enclosure, symmetrical around the 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 baffles ensure 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.
