- RMS Power: 100 watts (The maximum amount of continuous power the device is able to handle.)
- 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

Product Manuals
Q: How does the Metamaterial Absorption Technology work in the speakers?
A: Metamaterial Absorption Technology uses a complex maze-like structure with channels that absorb specific sound frequencies. These channels act as an acoustic black hole, absorbing 99% of unwanted sound coming from the rear of the tweeter. This eliminates distortion and provides a purer, more natural sound.
Q: What type of wireless connectivity does the speaker offer?
A: This speaker offers Bluetooth wireless connectivity.
Q: What is the purpose of the acoustic black hole in the speakers?
A: The acoustic black hole absorbs unwanted sound from the rear of the tweeter. This eliminates distortion and provides a purer, more natural sound.
Q: What are the dimensions of the speakers?
A: The LS50 Wireless II speakers have a height of 18 inches, a width of 24 inches, and a depth of 17 inches.
Q: Why are the speakers considered a revolutionary tool in the KEF acoustic armoury?
A: The speakers are considered revolutionary because they utilize Metamaterial Absorption Technology (MAT), a complex structure that acts as an acoustic black hole. This technology absorbs 99% of unwanted sound from the rear of the tweeter, eliminating distortion and delivering a purer, more natural sound.
Q: Do these speakers support Pandora streaming?
A: The short answer is yes. Pandora doesn't have a dedicated streaming protocol like some services, so there's no special compatibility required. You can use your phone or tablet's built-in Google Cast or AirPlay function to stream to the LS50W2. You can also use Bluetooth, but the quality will be lower so I don't recommend that.
A: One of the speaker is primary and other is secondary, Connection is needed between them for secondary speaker to play music. There are two ways to connect them 1. Interconnect cable (included) 2. Wireless I am using wireless connection which is working good. All your source inputs go into the primary speaker, like HDMI ARC from TV. etc.. These are not plugged into secondary speaker. Each speaker needs to be plugged into power socket.
A: KEF LS50 are passive speakers, which means they need to be connected to an amplifier or AV receiver. LS50 Wireless II are active speakers, they have built in amplifiers and they have wireless capability. I have LS50 Wireless II and am very happy with their performance.
