INtroducing the Spitfire Q Series
THE MOST POWERFUL. THE MOST DYNAMIC. THE MOST REVEALING CINEMA SPEAKERS WE HAVE EVER CREATED.
There’s a moment—usually just seconds into a film—when you realise you’re hearing something different.
Dialogue snaps into focus. Dynamics feel effortless. The room seems quieter, even as the sound becomes bigger, more immersive, more controlled.
That’s the Spitfire Q Series.
Designed from the ground up as a true Quasi Line Array, the Spitfire Q Series delivers array-level control, scale, and intelligibility from a single, architecturally discreet enclosure. No visual clutter. No system complexity. Just precision, power, and absolute confidence.
“After more than three decades of steering Artcoustic to a market-leading position in high-end home cinema, residential, and commercial audio, I set out to design a loudspeaker range that would define both a statement and a legacy.
The Q Series represents the culmination of everything we have learned in cutting-edge acoustic engineering and industrial design. Built for raw power, extreme output, and absolute control, it is engineered to meet the most demanding modern audio applications—from private cinemas to commercial cinemas and professional fixed installations.
The Q Series is without question the most advanced and most powerful loudspeaker range we have ever created, yet at the same time the most flexible and versatile.
— Kim Donvig, Designer & Engineer”
THE SPITFIRE Q4-3
The most compact model in the Q-Series, designed for installations where space efficiency and visual discretion are critical. Using a fixed quasi line-array configuration of 3-inch drivers, the Q4-3 delivers exceptional speech intelligibility, precise imaging, and tightly controlled dispersion tailored for cinema applications.
Spitfire Q6-3
The Spitfire Q6-3 extends the performance of the compact Q-Series by offering increased output capability while maintaining a slimline enclosure. Featuring an expanded fixed quasi line-array of 3-inch drivers, the Q6-3 provides improved coverage, higher headroom, and outstanding dialogue clarity across larger listening areas.
SPITFIRE Q4-5
The Spitfire Q4-5 represents the step into full-range performance within the Q-Series. Employing larger 5.25-inch drivers in a fixed quasi line-array configuration, the Q4-5 offers increased low-frequency extension, greater dynamic authority, and higher overall output capability compared to the smaller models.
The Spitfire Q8-5
The Spitfire Q8-5 is the flagship model of the Q-Series, engineered for large-scale cinema installations where maximum output, control, and realism are required. Utilizing an extensive fixed quasi line-array of 5.25-inch drivers, the Q8-5 delivers authoritative full-range performance with exceptional clarity, uniform coverage, and cinematic dynamics.
Artcoustic Q Series Infinity™ High-Frequency Lens
Developed specifically for the Artcoustic Q Series, the Infinity™ High-Frequency Lens is a precision wave-shaping system engineered to maximise coverage while maintaining control.
Its distinctive infinity (figure-8) geometry delivers exceptionally wide horizontal dispersion while narrowing vertical directivity, reducing array interaction and unwanted reflections. By time-aligning the high-frequency wavefront before it exits the enclosure, the lens improves coherence, clarity, and consistency across the listening area.
The result is expansive, even coverage with controlled vertical behaviour—ideal for stacked and multi-speaker Q Series installations.
Wide horizontally. Controlled vertically. Q Series precision.
Artcoustic Q Series Stretch™ Flare Control
Designed specifically for the Artcoustic Q Series, the Stretch™ Flare Control uses a fabric-stretched acoustic flare to precisely guide high-frequency energy from the tweeter into the room.
The integrated flare geometry supports controlled dispersion while maintaining a seamless, fabric-covered front surface. This ensures consistent off-axis response, improved clarity, and smooth integration with the Infinity™ lens system—without visual compromise.
The result is controlled, predictable high-frequency behaviour combined with a clean architectural aesthetic.
Guided sound. Hidden technology. Q Series control.
