Comparing Sound Quality: KEF LS50 vs KEF LSX

During my time with the KEF LS50 and KEF LSX speakers, I couldn’t help but notice the differences in sound quality between the two models. In this section, I’ll dive deeper into what sets these two apart and highlight some of the key aspects when it comes to their audio performance.

Comparing Sound Quality: KEF LS50 vs KEF LSX

The KEF LS50 speakers boast a Uni-Q driver that combines both the tweeter and mid/bass driver into one unit, providing an incredibly accurate and cohesive sound. This innovative design allows for better detail and imaging since the sound comes from a single-point source. Additionally, the LS50 has a frequency response of 79Hz – 28kHz which offers a decent bass extension for a speaker of its size.

On the other hand, the KEF LSX is a more compact and versatile option, featuring a 4-inch Uni-Q driver. One major advantage of the LSX is its wireless capabilities, allowing for easy connectivity and flexible placement options.

The LSX sports a frequency response of 54Hz – 28kHz, which is impressive for its size. However, it’s worth noting that the LSX may lack some of the precision and depth offered by the LS50 in certain scenarios.

To further examine the sound quality of the LS50 and LSX, I put them through various listening tests with different genres of music. Some of the key observations include:

  • For bass-heavy tracks, the LS50 truly shines with its larger driver, providing greater bass extension and impact compared to the LSX.
  • Vocal performance stands out on both speakers, but the LS50 offers a slightly more natural and lifelike rendition.
  • In terms of soundstage, the LS50 has a clear advantage, delivering an expansive and immersive listening experience, while the LSX still performs well but is better suited for smaller spaces.

Diving into the design and aesthetics of the KEF LS50 and KEF LSX models, it’s evident that the manufacturer prioritizes both form and function. I’ve been attracted to both models, captivated by their sleek, modern appearance and unique features. Allow me to break down the design elements of these two outstanding speaker series:

Design and Aesthetics: KEF LS50 vs KEF LSX

Firstly, let’s discuss the KEF LS50. This speaker model sports a timeless and elegant design. Known for its Uni-Q driver array technology, it enables a seamless blend of low and high-frequency sounds. That means you’ll get an exceptional listening experience.

The LS50 series is available in four different color combinations: Gloss Black, Gloss White, Titanium Grey, and Racing Red, accommodating diverse aesthetic preferences. Moreover, it features a curved front baffle providing optimal sound dispersion.

On the other hand, the KEF LSX also leaves a strong impression with its stylish forms. The LSX series showcases the signature Uni-Q driver array but in a more compact package. The LSX offers five vibrant color options: Black, White, Maroon, Olive, and Blue to match any interior decor. The speakers can either be mounted on stands or bookshelves. Compared to its sibling, the LSX is a more versatile and affordable option.

Here are some noteworthy design features of the KEF LS50 and KEF LSX:

  • Both models incorporate the Uni-Q driver array technology, which ensures optimal sound dispersion.
  • The LSX model is smaller and lighter, making it a more versatile option for various room sizes.
  • Numerous color options are available, allowing you to choose the style that best suits your taste and space.

Setup and Connectivity: KEF LS50 vs KEF LSX

In my experience with both the KEF LS50 and KEF LSX speakers, I’ve found the setup process to be relatively simple and straightforward, but with some key differences between the two. For those who prioritize easy connectivity and setup, it’s essential to understand the distinctions between the two models.

The KEF LS50, which is the more premium option, offers a wide range of options for connectivity. Designed for a more versatile and high-end setup, it provides:

  • Wired Connectivity: Traditional speaker wire inputs and binding posts for secure connections
  • Digital Inputs: USB Type B, Optical TOSLINK, and RCA/Coaxial inputs for digital devices
  • Analog Input: RCA phono input for turntables and other analog devices

In contrast, the KEF LSX is designed more for convenience and simplicity, making it a great choice for those who prefer a plug-and-play solution. It offers:

  • Wireless Connectivity: Bluetooth 4.2 with aptX for streaming from mobile devices and computers
  • Digital Input: Optical TOSLINK input for digital devices
  • Analog Input: 3.5mm auxiliary input for connecting analog devices

When it comes to setup, the KEF LS50 requires a bit more attention due to its wired connections. An external amplifier or receiver is necessary to power these speakers, so you’ll want to factor that into the overall setup process. Once the speakers are connected to the amplifier or receiver, they can be configured using the provided remote control.

On the other hand, the KEF LSX was designed with ease of use in mind, focusing on simplicity and a user-friendly experience. These speakers have a built-in amplifier, so no additional equipment is needed.

They can also be controlled using the KEF Control App, making it easy to adjust settings and preferences right from your smartphone. Additionally, the LSX features a unique wireless inter-speaker connection, so there’s no need for a cable between the two speakers, freeing up space and reducing clutter.

Size and Portability: KEF LS50 vs KEF LSX

When it comes to comparing the KEF LS50 and KEF LSX speakers, I’ve found that size and portability play a major role in determining which one is more suitable for a specific space or user. Let’s dive into the size differences and portability aspects of these two models.


The KEF LS50 speakers are larger and heavier compared to the LSX model. With dimensions of 11.9″ x 7.9″ x 10.9″ (H x W x D) and weighing 15.87 lbs, these speakers are intended for a more permanent setup. However, the greater size and heft contribute to their impressive sound performance.

On the other hand, the KEF LSX speakers are more compact and lightweight, measuring 9.5″ x 6.1″ x 7.1″ (H x W x D) and weighing around 7.9 lbs. This makes them easier to move around and set up in various locations. The smaller size might be more suitable for smaller living spaces, bedrooms, or offices.

Now, let’s discuss the portability factor:

  • KEF LS50: Due to their larger size and heavier weight, these speakers are less portable and ideally suited for a dedicated listening area. However, they provide incredible audio performance and are worth the investment if you’re looking for a more static setup.
  • KEF LSX: Much more portable than their bigger brothers, the LSX speakers can easily be moved around to different rooms or taken on the go when needed. Their compact design makes them perfect for users who prioritize flexibility and portability over the sheer power of bigger speakers.

Another aspect to consider in terms of portability is the ease of setup. The LSX speakers are designed with wireless connectivity and a user-friendly app, making it simple to set up and connect to various streaming services. In contrast, the LS50s require a wired connection, which may add some complexity to the setup process.

The KEF LS50 and KEF LSX each have their own strengths when it comes to size and portability. The LS50s might be more suitable for those who prioritize audio performance and a static setup, while the LSXs cater to users looking for compact, easily portable speakers with wireless connectivity for a more convenient setup experience.
