The simple, straight lines of the LS50 give it a timeless look, while the curved sides and textured finish of the LSX add an element of style and sophistication. Both speakers are made from durable, high-quality materials, though the LSX is slightly heavier due to its larger size. In terms of build quality, both speakers are top notch and should last for many years.

Both the LS50 and the LSX have a unique design that lets them make the best sound possible.

How We Choose Which Product is The Best

1. Driver type

KEF’s Uni-Q driver array innovation is present in both the LSX and LS50W speakers. The latest Uni-Q drivers were made just for these models, so they can both make a sound that is very wide, clear, and powerful.

Also, they made stereo sound much better by putting the tweeter in the middle of the midrange and bass cones. This not only improves the clarity, precision, and vividness of the music, but also does so throughout an expanded stereo field.

Winner: Tie

2. Nominal Impedance

The nominal impedance is a further crucial criterion that needs to be prioritized. The ideal impedance for your speaker is 6–8 ohms, although either will work. If the high-impedance speaker is not properly hooked up to a power source, the sound quality will be worse.

Overheating from low impedance can destroy an amplifier. Many people think that the nominal impedance of 8 ohms, which both of these speakers have, is the best for sound reproduction.

Winner: Tie

3. Frequency Response or Frequency Range

How well your speakers play at high or low volumes is indicated by their frequency response, or frequency range. The ability to reproduce low, midrange, and high tones precisely and to an acceptable degree is known as the “frequency response,” and it tells our ears that the sound system is of good quality.

The lower the number, the deeper and more perceptive the bass. Any refresh rate of 50 hertz or below is legal.

It’s plain to see that LS50W can reach 45 Hz, whereas LSX tops out at 54 Hz. A more precise and detailed soundstage is achieved with the LS50W’s superior frequency response.

Winner: LS50W

4. Driver Size

Large speakers, like ceiling speakers, don’t just boost the volume or add more bass; they also make for a great listening experience. Speaker size is an important consideration. Higher power drivers are optimized for lower frequency ranges. Find a speaker that can make a wide range of audible frequencies for the best listening experience.

Even though smaller speakers may be easier to handle in terms of size and budget (if you’re not buying a brand-new high-end model), larger speakers usually have more output. Also, when people buy a speaker, the sound quality is the thing they care about the most.

Size-wise, LSX is around 50% smaller than its LS50W counterpart. The LS50Ws is far more powerful and louder than the LSX, making it better suited to larger rooms. Even in large rooms like a living room or an open office, the LSX’s volume level will not meet your expectations.

Winner: LS50W

5. Maximum Output (SPL)

SPL is the same as a tone’s sound level. Decibels (dB) are the units of measurement. At one meter from a speaker, the maximum sound pressure level (SPL is the loudest sound level (in dB). Two values, the speaker response level and the overall power, are used in the calculation (in watts).

Your brain’s internal volume meter will be more accurate if you can hear more at the same SPL. Due to this, it will be much easier to spot any problems with the audio balance, which will help you understand the quality of the sound as a whole.

Since the LS50W has a higher SPL rating than the LSX, this means that the LS50W needs less power to make clear, lively sound.

Winner: LS50W

6. Amplifier type

If you want a more practical speaker, an amplifier class is a must-have. There are four different classes: Class A, Class B, Class AB, and Class D. Class-D amplifiers, in comparison to Class-AB amplifiers, use more efficient switches that generate less heat.

The LS50W’s woofer was made with a class D amplifier, but the device’s tweeter was made with an AB amplifier. In contrast, LSX has powered both of their drivers with a D-class amplifier.

Winner: LSX

7. Design

When comparing the LSX to the LS50W, the most noticeable difference is in the car’s exterior. The textured fabric on the LS50Ws may be easily cleaned with a vacuum, whereas the LSXs are made entirely of plastic.

The easily recognizable shape isn’t just a cosmetic choice; it’s also an acoustic element that contributes to KEF’s commitment to a fully integrated approach to industrial and sonic design. The LS50W Wireless can be as subtle or flashy as you choose thanks to its three color options: Kef LS50 Titanium Gray/Kef LS50 Red, Kef LS50 Gloss Black/Kef LS50 Blue, and Kef LS50 Gloss White.

However, the LSX is small and sophisticated, making it incredibly adaptable. It also has a wonderful design that works in any setting. There are five distinct hues available on the system: green olive, red, white gloss, black, and blue. The KEF R300 is the finest option if you’re looking for a bookshelf model.

Winner: LS50W

8. Features

Using the controls that come with the LS50W, you can change how the different speakers sound. This selection capability extends to apps on iOS and Android. The app’s visual appeal, usability, and layout are all top-notch.

It controls the streaming capabilities (DLNA and Tidal) and gives you a lot of leeway to fine-tune the speakers’ output to your specific space. Nonetheless, there is room for development.

There are times when it appears irresponsible, and other times when it appears elated. Dase OEIFs have exclusive compatibility with KEFs in streaming mode, and switching between the two physical inputs is possible. Either the included remote or the touch controls on the main speaker have to be used to switch inputs, which could be a pain.

Both speakers are Bluetooth enabled, and they are compatible with streaming services like Tidal and Spotify from your mobile device. Both the Audioengine A2+ and the HD3 are versatile Bluetooth wireless speakers.

KEF LSX’s decision to need the installation of two apps is mildly annoying. To begin configuring your KEF speaker for wireless streaming, download the KEF Control app.

After that, you’ll need to install the KEF Stream app on your device so you can listen to music from your local library or your preferred streaming provider. After you’ve gotten everything set up, you’ll have access to a number of different streaming services.

Apple AirPlay 2, Spotify Connection, Tidal, and Bluetooth audio can all be used with the LSX. The KEF wireless system is compatible with different devices and works just as well as the Bluetooth speakers.

Winner: LS50W

9. Cost

Let’s talk about the most common approach suggested for this contrast. These two high-quality speakers couldn’t be more different in cost. The LSX is less expensive than its more prestigious sibling, the LS50W, because it is significantly smaller. If you’d rather not spend the extra money on the LSX, you can get the LS50W for $2399.99.

The KEF LS50 wireless is more expensive than the LSX, but it’s money well spent.

There’s no denying the high price tag associated with both of these speakers. The sound quality of these products can’t be beat, and if you’re an audiophile who puts quality over price, you’ll agree that they’re worth the high price.

Winner: LSX

Will KEF LSX work if I don’t have a wireless network?

This is possible, yes. The KEF Control/Stream apps and streaming services like Tidal and Spotify Connect require an active internet connection, so hooking up the LSX to your home network is a must.
