KEF’s Reference, Blade speakers updated with metamaterials

By

KEF has released the newest iteration of its flagship Reference and Blade product lines. These high-end speakers are getting a performance upgrade featuring KEF’s latest acoustic innovations, including a new high-end 12th Generation Uni-Q with Metamaterial Absorption Technology (MAT). Uni-Q is KEF’s proprietary driver technology that features the prominent star shape in the center and is found on all of the high-end speakers in their lineup.

According to KEF, metamaterials are “specially developed structures that use existing materials in such a way that they exhibit new, desirable properties that are simply not found in naturally occurring substances.” The company claims that adding the new MAT technology removes 99% of distortion and unwanted sounds from the rear of the speakers.

Blade Series

The KEF Blade is known for its unique visual design and Single Apparent Source technology. When developed in 2009, engineers sought to design a speaker that is extremely transparent and creates the illusion that sound is radiating from a single area, rather than from separate speaker towers. This can help music or movies feel more immersive and lifelike.

KEF offers both the Blade One and Blade Two, with the latter designed for smaller listening environments. You can buy them right now in their four standard finishes (piano black/gray, arctic white/champagne, charcoal gray/bronze, frosted blue/blue), but if you desire something more bespoke, four special order finishes will be available in June 2022: Piano black/copper, frosted blue/bronze, charcoal gray/red, racing red/gray.

  • Blade One Meta: $35,000 per pair
  • Blade Two Meta: $28,000 per pair

Reference Series

The KEF Reference has been a staple in the speaker industry for decades. KEF boasts that this new iteration has “pipe organ” depth in the bass response and a pure midrange and treble response. The Reference line has a more traditional speaker appearance and is available in bookshelf size with the Reference 1 Meta, plus 2-woofer and 5-woofer tower options in the Reference 3 Meta and Reference 5 Meta. The Reference line also features two left-center-right (LCR) speaker options, the Reference 2 Meta and Reference 4 Meta, which the Blade series does not offer.

LCR speakers are designed for home theater use and can be used as a center channel when placed horizontally, or as left and right front channel speakers when oriented vertically. If opting for the Reference 1 Meta bookshelf design, KEF also offers the S-RF1 Floor Stand to accompany them. Similar to the Blade series, the Reference is available in a myriad of finishes (satin walnut/silver, high-gloss white/champagne, high-gloss black/gray) and two special order finishes: High-gloss white/blue, and high-gloss black/copper.

  • Reference 5 Meta: $22,000 per pair
  • Reference 3 Meta: $15,000 per pair
  • Reference 1 Meta: $9,000 per pair
  • Reference 4 Meta: $8,000 each
  • Reference 2 Meta: $6,000 each
  • S-RF1 Floor Stand: $1,200 per pair

LG updates its XBoom 360 speaker with better sound, battery, and water resistance
LG XBoom 360 X03 speaker.

We were pretty impressed by LG's XBoom 360 portable party speaker when we put one to the test earlier in 2022, but despite the good tunes and fun lighting, we noticed a few places where it could improve. Battery life, at just 10 hours seemed meager, and what's a portable Bluetooth speaker without the ability to take a splash or two?

Looks like LG took our comments to heart. The latest addition to the XBoom family is the $300 XBoom 360 X03, a much more robust speaker in every way, that still keeps the original's unique shape, 360 sound, and customizable light effects. LG says it's available to order immediately from LG's website and authorized retailers, but at publication time, we couldn't find any links to do so.

KEF’s second-generation LSX II connects to all your audio
The red KEF LSX ii is sitting on a mantle next to some books and an audio device.

With its lineup of high-end, high-design speakers, KEF commands a unique spot in the premium consumer audio space. And now, KEF is launching the second generation of its popular LSX-powered speakers. The LSX was something of a runaway hit for KEF, so the LSX II is really more of a modern refinement—namely folding in some additional connectivity, added design polish, and wireless connectivity befitting of 2022.

First, the sound quality on deck here should be in keeping with KEF’s track record. Featuring the unique 11-inch Uni-Q driver technology that KEF designs to fit perfectly into its speakers, this speaker places the tweeter at the dead center of the woofer, which is meant to reproduce sound in a much more natural way. Not only is this driver array designed to give the speakers an impressively focused sound, it also contributes to KEF’s unique exposed woofer design with the visually contrasting tweeter at the center.

Klipsch’s latest Reference speakers promise better sound with less distortion

Each line features floor-standing speakers, floor-standing speakers with built-in Dolby Atmos height modules, bookshelf speakers, and center channels, but the Reference line also includes two subwoofers, while the Reference Premiere line includes bi-directional corner surround speakers. None of these are new models per se; instead, Klipsch has updated all of the speakers with a few new features.
