Акустическая система KEF Q950 White

The KEF Q950 is the new flagship model of the Q series, featuring KEF's unique Uni-Q driver technology, paired with a new long-throw 200mm (8") woofer and similarly sized passive drivers (ABR).

From a technical point of view, there are a number of improvements that have touched on cabinets, crossovers and speakers, which in total bring the quality of the reproduction of the new Q-series speakers closer to the sound of the older R and Reference lines.

The tweeter of the Uni-Q module received an improved damping chamber, resulting in improved detail and dynamics of the sound at high frequencies. In floorstanding models, the Uni-Q driver is "packed" in a closed cabinet compartment, isolating it from the influence of low-frequency speakers, thus, the middle of the sound spectrum has become even more detailed and cleaner, while intermodulation distortion has been reduced.

The developers put a lot of effort into improving the low frequencies, and the main goal was not so much to increase the amount and depth of the bass, but to increase the naturalness of the sound. For this, the structure of the aluminum cones and the centering washer in the woofers were modified. For passive radiators used in floor models, the entire suspension system has been optimized, including a new internal suspension made of rubber and a larger external suspension. As a result, the course of the membranes increased, and the tuning frequency of passive radiators decreased. Additionally, new low-distortion inductors are used in the low-frequency part of the crossover filters. Together, these improvements have improved control, intelligibility and bass dynamics.

The most noticeable design changes have been made to the bookshelves of the series, having received a new layout: the Uni-Q driver has moved to the exact center of the front panel, and the new bass-reflex port has been moved from the front to the rear panel. The restructuring of the bookshelf cabinets was started to reduce the coloration of the sound due to cabinet distortions. Simulated in numerical experiments, the port with bells on both ends removes detrimental midrange response and reduces turbulent noise that can cause audible distortion at high volumes. Another difference between the updated speakers is the developers' refusal to use a two-wire connection, so the terminal board has acquired only one pair of speaker connectors.
