Features
3-Way System Design: The KEF Q11 Meta floorstanding loudspeaker employs a 3-way system design that features KEF's Uni-Q driver array, consisting of a 0.75" aluminum dome tweeter and 4" midrange driver, plus three 6.5" bass woofers to ensure precise separation of high, mid, and low frequencies. This updated configuration significantly improves detail and clarity, bringing your music and movie soundtracks to life.
Uni-Q Driver Array: KEF's 12thgeneration Uni-Qdriver array with MAT is found in the Q11 Meta floorstanding speaker. Uni-Q technology places the tweeter precisely at the acoustic center of the midrange cone, so both act together as a single point source to disperse sound more evenly throughout the room. The result is the elimination of the limited "sweet-spot", therefore allowing everybody sitting at different spots in the room to experience and enjoy the same natural, detailed sound. With Uni-Q's single point source design all frequencies reach your ear at the same time. The sound is therefore more accurate and realistic than with conventional loudspeakers, where the output from each separate driver arrives at slightly different times, causing the sound to be smeared and less natural sounding.The Uni-Q driver array is made up of a 0.75" aluminum dome tweeter and a 4" aluminum midrange cone driver.
- 0.75" Aluminum Dome Tweeter:At the center of the Uni-Q driver array is a 0.75" aluminum dome tweeter that utilizes a conical waveguide which couples the tweeter dome to the metamaterial absorber for ultra-wide dispersion and greater depth. The re-engineered tweeter gap damper strategically places two rings of porous material to tame the resonances and imperfections effectively, greatly improving detail and clarity. The tweeter motor system has also been redesigned to maximize the transmission of energy from the rear of the tweeter to the MAT absorber. The area of the tweeter rear chamber vent is increased by 250%, allowing more sound to reach the metamaterial absorber and therefore its effectiveness. This also significantly reduces the acoustic pressure behind the dome, allowing the tweeter to operate more linearly leading to lower distortion still.
- 4" Aluminum Cone Midrange:The 4" midrange driver features an aluminum cone structure that has been engineered to reduce cone breakup and improve midrange performance. The Flexible Decoupling Chassis of the Uni-Q's midrange dramatically reduces coloration of the sound caused by midrange frequency vibration transmission to the cabinet, while also mitigating the potential of additional sound created by the driver basket that occurs with traditional decoupling methods. It works by decoupling the massive midrange motor from the Uni-Q chassis, dissipating its vibration before it can travel to the cabinet and be radiated as unwanted sound. The aluminum cone midrange also employs KEF's ingenious Z-flex surround which guides the sound from the tweeter across the surround without any disturbance or secondary radiation.
Metamaterial Absorption Technology (MAT): The crucial advancement of KEF's Uni-Q driver array is the integration of their Metamaterial Absorption Technology (MAT). MAT is a highly complex "maze-like" structure that absorbs unwanted noise from the rear of the driver, eliminating the resulting distortion and providing a purer, more natural sound. Metamaterials are specially developed structures that use existing materials in such a way that they exhibit new properties. MAT’s tuned channels absorb 99% of the unwanted sound from the rear of driver, compared to around 60% absorption from loudspeakers using different approach.
Triple 6.5" Hybrid Aluminum Bass Woofers: The Q11 Meta floorstanding speaker houses three 6.5" bass woofers that feature a hybrid structure with a shallow, concave, aluminum skin atop a paper cone which gives stiffness to achieve a piston-like movement for better bass punch and speed. Combined with a 3D FEA-optimized surround geometry, these newly designed hybrid bass woofers significantly improve linearity at higher excursions. The result is precise and agile bass performance even at high output levels.
Refined Crossover: Toachieve a smooth and natural sound between drivers, KEF engineers take more than 1,000 specific measurements for each speaker model using a custom-built reference microphone array in their anechoic chamber in Maidstone, UK. These extensive on and off-axis measurements allow KEF's team to thoroughly understand each model's acoustic interactions, enabling precise crossover design through advanced simulation and prototyping. This meticulous process guarantees precise signal path optimization and the best possible audio performance.
Bass Reflex Cabinet: The KEF Q11 Meta floorstanding speaker employs a bass reflex cabinet with a rear-firing port for bigger bass response and greater efficiency. The flared port, modeled with computational fluid dynamics, minimizes turbulence and reduces "chuffing" noise. This enables the ported speaker to produce bass that is cleaner and more controlled. The speaker cabinet feature a contemporary minimalist design that is available in Satin Black, Satin White, or Walnut finish - designed to blend effortlessly into practically any room's decor.
- Shadow Flare: Shadow Flare reduces unwanted cabinet diffraction , allowing the speaker's 12th generation Uni-Q with MAT to work at its highest potential. Shadow Flare is a precision-designed surface that extends the waveguide effect of the Uni-Q driver array. This means the tweeter no longer has a line of sight to the cabinet edges, creating a "shadow region" where the potential for diffraction is highest, minimizing the acoustic impact to negligible levels. The exceptional clarity and reproduction of fine details make for an improved listening experience.
- Magnetic Grille: A color-matched grille is included with the Q11 Meta floorstanding speaker. The magnetic fixing provides a secure and precise fit, in keeping with the clean and seamless styling of the Q Series.
Note: A port plug is included if you have to position the speaker closer to the back and side walls than recommended in order to prevent unwanted distorted "muddy" bass. The port plug will help to tighten the bass for a more detailed sound.
Binding Post Terminals:On the rear of the speaker cabinet is a pair of gold-plated binding post terminals that will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana plugs (single only). Plastic inserts must be removed from the binding posts to use banana plugs. The gold-plated binding post terminals provide excellent audio signal transmission and resistance to corrosion.
Mounting & Placement Options:The included outrigger stabilizers screw into the bottom of the speaker cabinet and provide a larger footprint for greater stability.The supplied rubber feet will thread into the bottom of the otrigger stabilizers to provide safe placement on almost any flooring - including carpet, hardwood, vinyl, ceramic, and laminate.
- A pair of floorstanding speakers should be positioned 5' to 10' apart.
- They should also form an equilateral triangle with the main listening position.
- The speaker can can be angled inward ("toed-in") toward the main listening area to improve stereo imaging and soundstage.
- The speakers should be placed at least 9" from the back wall due to their rear-firing port and 20" from side walls.
Note: The flloorstanding speaker should always be used with the outrigger stabilizers and rubber feet installed for maximum stability and optimum sound quality.
Q Meta Series: The Q Meta Series is quipped with innovative technology from KEF, including their Metamaterial Absorption Technology(MAT) and KEF's12thgeneration Uni-Qdriver array to ensure exceptional sound quality - making it an ideal choice for both stereo and home theatre setups.
