British hi-fi brand KEF has announced the launch of the latest speakers in its premium Blade and The Reference series.
According to KEF, these two ranges demonstrate “how innovation and design can create the most accurate and realistic sound with acoustics in mind.”
The Reference series is made up of two three-way floorstanding speakers, a three-way standmount speaker, and two three-way centre speakers that can be used as Left-Centre-Right (LCR) speakers.
Two speakers make up Blade range in the Blade One Meta and Blade Two Meta, and they are certainly one of the more unique-looking efforts, almost looking like a surfboard standing upright.
Acoustics have dictated the look of the Blade, the complex parabolic curves of acoustically inert cabinets have been engineered to eliminate any standing waves that could affect the sound. Inside the cabinet, the Blade benefits from the KEF’s latest speaker advancements, using Metamaterial Absorption Technology (MAT) – a material that absorbs 99% of wanted sound – to reduce distortion and produce a purer sound.
This is alongside a bespoke 12th generation Uni-Q driver array, which is further complimented by the Single Apparent Source technology. The goal of this tech is to achieve the “acoustic ideal of a point source, where low, mid and high frequencies radiate from one point” for a more coherent performance across all “all audible frequencies”.
The Reference take on a more traditional appearance with their elegant form factor. All cabinets have been designed using finite element analysis (which simulates physical phenomenon) to decipher the ideal shape and bracing geometry to minimise secondary radiation from the sides. By using Constrained Layer Damping, and remaining vibrations are turned into heat.
They also use the Uni-Q drivers with Metamaterial Absorption Technology, the contours of the dome within the speaker’s midrange horn and surround have been computer-optimised for smoother transition into the cabinet. And KEF’s patented tangerine waveguide manages the airflow to recreate the “wide, even spread of a natural sound field”, dispersing high-frequency imaging throughout a room.
Both speakers are full of technology and that’s certainly had an effect on the asking price, as neither the Blade or The Reference speakers come cheap. The Blade One Meta and Two Meta sell for £30,000 and £22,500 respectively, while The Reference series ranges from £17,500 for the Reference Meta 3 to £4,750 for the Reference Meta 2.
