Customers express satisfaction with the LS50 WIRELESS II Bookshelf Speakers, highlighting the superb sound quality, ease of use, and beautiful design with high-quality materials. However, some customers have reported connectivity issues. Additionally, a few customers noted that the bass is not very heavy.

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.

R3 Meta redefines bookshelf speaker’s performance. Sharing the same drivers as the range-topping R11 Meta, the R3 Meta is a true three-way design. It has a 12th generation Uni-Q driver array with MAT and a powerful 6.5” hybrid aluminum bass driver that pushes performance to the extreme.

No AVR Needed - Thanks to a custom engineered built-in amplifier, these powered speakers maximize sound output and quality — without connecting to an audio receiver. Featuring 192kHz / 24-bit decoding through all digital inputs, your Nines will flawlessly reproduce high resolution sounds straight from your TV, PC or streaming source.
