The LSX is another award-winning pair of wireless speakers made by the renowned British HiFi brand KEF. It is an all-in-one music system that caters to the demands of modern-day users and delivers exceptional sound quality. The KEF LSX is probably one of the very best wireless HiFi speakers out on the market and listeners who have sufficient budgets should certainly check them out.
It uses the iconic KEF Uni-Q driver array where it does not only produce amazing stereo imaging but also delivers vivid sonic performances with a wide sweet spot. The Uni-Q array is a 4.5″ (115mm) aluminum alloy cone low-frequency driver with a 0.75″ (19mm) aluminum dome tweeter right in the middle. As you can see the KEF LSX is quite a compact size wireless speaker with a small driver and probably won’t be able to dish out deep rumbling bass frequencies. For most music genres, this might not be an issue but if you are planning to use these wireless speakers for home theater or video gaming use or both, you will definitely need ample deep bass output.
The bass performance of your sound system will play a major role in providing you with an exhilarating home cinematic and/or gaming experience. To get to that level of low-end performance, we can integrate a powered subwoofer into the mix, but the question will be which sub should you go for. We will be preparing a list of the best matching subwoofers to pair with the KEF LSX, and this list will be shared with you later on. Right after we have learned more about the sonic characteristics and prowess of the KEF LSX wireless HiFi speakers.
