The Answer is always in the Q
The new Q Series with MAT™ always has the right sound solution for you
Equipped with innovative technology from our premium ranges, the Q Series now features Metamaterial Absorption Technology (MAT™) and the 12th generation Uni-Q driver array. This ensures exceptional sound quality, making it an ideal choice for both stereo and home theatre setups.
The comprehensive line-up caters for any room size, budget or application with models including floorstanding, bookshelf, centre channels and on-wall HiFi speakers. With the versatility to seamlessly mix and match, the Q Series can adapt to evolving audio needs. Colour-matched grilles are included with the speakers.
Metamaterial Absorption Technology (MAT™)
The crucial advancement in the Q Series is the integration of Metamaterial Absorption Technology (MAT™). MAT is a highly complex maze-like structure that absorbs 99% of the unwanted noise from the rear of the driver, eliminating the resulting distortion and providing a purer, more natural sound.
Uni-Q®
A 12th generation Uni-Q® driver array with MAT™ is found in all eight models of the Q Series. Uni-Q® acts as a single point source to disperse sound more evenly through the room, allowing everybody, wherever they are in the room, to enjoy the same natural, detailed sound for an immersive entertainment experience.
Speaker Performance
3-way speaker
The evolved Q Series has been upgraded from a 2.5-way to a 3-way system design which ensures precise separation of high, mid, and low frequencies. This updated configuration significantly improves detail and clarity, bringing your music and movies to life.
Deep and clean bass
The Q Series features a hybrid bass driver design that provides stiffness to achieve a piston-like movement for better bass punch and speed. Combined with a port modelled using Computational Fluid Dynamics (CFD), this results in precise and agile bass management even at high output levels.
Refined crossover
A critical component of the Q series is the refined crossover, which ensures seamless integration of all speaker parts. More than 1,000 specific measurements are taken for each speaker model, allowing precise signal path and optimisation for best possible performance.
Shadow flare
Derived from the flagship models, Shadow Flare is a carefully profiled transition that extends the waveguide effect of Uni-Q. This design reduces unwanted cabinet diffraction, allowing the treble to escape naturally without reaching the cabinet edges. The result is vastly improved fine detail reproduction.

Hope there will also a white paper and some measurements out soon.
