The Uni-Q driver’s concentric design ensures precise time alignment and wide dispersion, resulting in a coherent and detailed soundstage. The LS50 Meta, on the other hand, is equipped with KEF’s Uni-Q driver array, which integrates a 5.25-inch midrange driver with a 1-inch vented aluminum dome tweeter at its acoustic center. The tweeter, known for its wide dispersion and smooth frequency response, ensures detailed and natural high-frequency reproduction. The woofer’s wood fiber cone material provides excellent stiffness and damping characteristics, resulting in accurate and controlled bass response. The Rubicon 2 features Dali’s proprietary drivers, including a 6.5-inch wood fiber woofer and a 29mm soft dome tweeter. The driver technology employed by the Dali Rubicon 2 and the KEF LS50 Meta plays a vital role in shaping their sonic performance. Both speakers exude a sense of precision and durability, making them visually appealing additions to any listening room. The LS50 Meta’s enclosure is built using constrained layer damping technology, which minimizes resonance and enhances the clarity of the sound produced. The LS50 Meta, on the other hand, boasts a distinctive and minimalist design with its Uni-Q driver array integrated into a solid, braced enclosure. The cabinet is constructed from high-density fiberboard (HDF) and features Dali’s signature baffle design, which reduces diffraction and enhances overall sound reproduction. The Rubicon 2 exhibits a sleek and elegant appearance with its curved cabinet and meticulous craftsmanship. Design and Build Qualityīoth the Dali Rubicon 2 and the KEF LS50 Meta showcase outstanding design and build quality. By examining their construction, sonic characteristics, and value proposition, we hope to provide valuable insights that will assist you in making an informed decision based on your specific audio preferences and room requirements. This in-depth comparison aims to explore the unique features, design philosophies, driver technologies, and overall sound quality of these speakers. This leads to improved clarity, with exceptional depth and detail.In the realm of high-end bookshelf speakers, the Dali Rubicon 2 and the KEF LS50 Meta stand out as exceptional choices known for their impeccable audio performance and innovative engineering. Using Computational Fluid Dynamics (CFD), 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. The result of such meticulous attention to detail is the lowest coloration of any speaker in its class. LS50 Meta’s baffle is engineered from an injection-moulded Dough Moulding Compound (DMC), while inside the cabinet cross bracing and Constrained Layer Damping (CLD) combine to deaden internal vibrations. The result is cleaner, more precise sound. It’s smooth curved surfaces help radiate sound out across the baffle without any interference from hard edges, which cause diffraction. LS50 Meta’s low-diffraction, curved baffle is precision modelled around the Uni-Q driver array. LS50 Meta is such a loudspeaker, and enhancements over the legendary LS50 include Driver Performance Optimisation and patented off-set flexible port for the best acoustic performance and an incredible immersive sound. Great loudspeakers disappear, leaving just the music. This new driver array delivers reduced coloration, less distortion and a sound that is more transparent and life-like than previously possible, all dispersed evenly throughout the room. Using advanced simulation and analysis tools, our engineers have developed the 12th generation Uni-Q with MAT. A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.Įvery spot is the sweet spot 12th generation Uni-Q with MAT
