- Peak Power Handling: 200 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
- Impedance: 8 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
- Minimum Frequency Response: 40 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 55 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Sensitivity: 85 decibels
- High Resolution Audio: true (Hear music the way musicians and sound technicians intended it to be heard. Products that support hi-res audio deliver audio signals with a dynamic range and bandwidth far greater than that of a standard CD so you'll be able to enjoy pure music with outstanding sound quality. The device supports high-resolution audio signals, which more closely resemble the quality of music as it was originally recorded, with more texture and detail than can be heard via typical music streaming services or CDs.)

When it comes to physical technology, LS50 Wireless II takes its lead from KEF’s LS50 Meta passive loudspeakers. A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology1 (MAT) is a highly complex maze-like structure, where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural sound.
- KEF LS50 Wireless II: The lowdiffraction, curved baffle is precision modelled around the Uni-Q driver array, while eye-catching heat sinks and colour-matched ports are located on the well-equipped rear
- Subwoofer Output: For even more impact and bass extension, LS50 Wireless II features two subwoofer outputs, one on each speaker
- Features: Comprehensive applications and connectivity
- Music: Play all major music services and supports all major audio formats
- Tecnology: Metamaterial Absorption Technology for pure, natural sound

When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural sound.

For LS60 Wireless KEF’s engineers have seamlessly combined elements of the iconic Blade’s Single Apparent Source technology, a specially designed 12th Generation Uni-Q driver array, the revolutionary Metamaterial Absorption Technology , Uni-Core bass drivers and much more besides.

The exceptional acoustic performance of Coda W is powered by KEF’s 12th generation Uni-Q driver array, delivering precise and natural sound reproduction. Featuring the latest Bluetooth 5.4 aptX for seamless wireless streaming, an integrated phono preamp for direct turntable connection, and versatile connectivity for TVs, desktop computers, and beyond, it offers uncompromising flexibility.

The LS50 Meta has inherited its distinctive good looks from the original LS50, with its low-diffraction, curved baffle precision modelled around the Uni-Q driver array. The curved front is subtly mirrored by the gently radiused rear panel, while both the port exit and speaker terminals have been elegantly recessed and softened visually. The LS50 Meta’s extremely rigid cabinet is optimised for performance, with smooth curved surfaces that help radiate sound out across the baffle without any interference
