The Kef LS50 Meta is the replacement for the iconic LS50 speaker which was released way back in 2012 as a limited anniversary model and was one of the most award-winning speaker products ever released by KEF, receiving accolades from such publications as Stereophile, What Hi-Fi, and The Absolute Sound. So the new LS50 Meta have a lot to live up to.
Pushing the Technological Boundaries
The new KEF LS50 Meta pushes the technological boundaries in its mission to create the best possible sound, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that eliminates unwanted sound from the rear of driver, resulting in a purer, more natural performance. MAT is the physical manifestation of that drive. The result of a joint development project with the Acoustic Metamaterials Group, MAT breaks completely new ground in loudspeaker design….
LS50 Meta’s baffle is engineered from an injection-moulded Dough Moulding Compound, while inside the cabinet cross bracing and Constrained Layer Damping combine to deaden internal vibrations. The result of such meticulous attention to detail is the lowest coloration of any speaker in its class. Using Computational Fluid Dynamics, the port flare and profile of LS50 Meta’s patented off-set port is calculated to delay the onset of turbulence, and the flexible port walls prevent resonances from colouring the midrange. This leads to improved clarity, with exceptional depth and detail..
Redesigned and Improved
KEF's trademark Uni-Q driver has also been redesigned and improved, incorporating the new Meta technology. The Kef LS50 Meta certainly shares a likeness with the original. But while LS50 is a great speaker, LS50 Meta and the technological advances it boasts offer a truly dramatic improvement in sound quality…
The KEF S2 Floor stands
The Kef S2 Floor Stands are optional but a must in our opinion, improving the performance and making them look simply stunning in any room.
Features
- Integrated cable management system cleanly conceals all cables
- Steel and aluminium construction provides rigidity and stability
- Space available for the addition of inert filler for further stability
- Ideal for LS50 Meta, LS50 Wireless II and other KEF Bookshelf Speakers
Speaker positioning is critical when it comes to creating the ideal soundscape. KEF S2 Performance Speaker Stands were engineered by our engineers to ensure standmount speakers sound at their best. This means ideal driver height positioning, steel damping plates accompanied by aluminium tube and base plates and space available for the addition of inert filler for further stability.
