KEF LS LUXE vs LS50 Wireless II review
We’ve had the new KEF LS LUXE at our shop for a couple months now, and I noticed quite a few people tossing up between them and the LS50 Wireless II.
Makes sense. The LUXE meet the exact same needs: they’re both standmount streaming active speakers, with the same inputs, and tasteful (albeit different) aesthetics.
The LS50W2 are known for sounding good (and they do) so is it worth looking at the pricier LUXE?
I had a chance to hear both back to back a few times.
Both definitely have KEF’s LS house sound. That is to say: the treble is detailed and well-imaged, but smooth and never fatiguing. The midrange leans warm, and feels like it wraps around you and fills the room. And the bass is kept in line, sacrificing some extension to keep dynamics and tonal clarity.
However, the LUXE definitely had better extension, and when I cranked it, the bass stayed grippy. The LS50W2 on the other hand lost a bit of bass dynamics at higher volumes. Also at volume, the LUXE had better midrange detail. Instruments had a better sense of timbre. Big passages had more of an epic feel.
If you look at the tech KEF added to create the LUXE, these improvements to bass and loud volume performance make sense.
LS LUXE has a 6.5-inch driver versus the 5.25-inch LS50W2. Bigger drivers can displace more air volume from the same excursion (distance moved). So bigger drivers have a higher ceiling on bass and volume performance.
The LUXE also has more air volume inside the cabinet, because their shape and material reduces the need for internal bracing. This basically softens the air spring that the driver has to fight every time it moves.
Plus, KEF added a feedback loop (VECO technology) that monitors the driver’s movement, and corrects differences between it and the audio signal (in the DSP, before the amp). Since it’s harder for a speaker to keep it together with extreme excursion, VECO basically acts to improve bass and midrange performance at volume.
Pretty cool thing.
Anyway, the general rec I took away from this is: for lower volumes and smaller rooms, the LS50W2 will still provide most of the experience—especially if you get a sub. Otherwise, and if audio performance is a priority, the LS LUXE would be the better pick (if the budget makes sense).
Happy listening!
