LG Display’s ‘invisible’ speaker brings sound to any surface in your car

By Derek Malcolm November 21, 2022

LG Display, the innovative arm of LG Electronics responsible for the company’s cutting-edge rollable OLED TV and wraparound display tech, is at it again. Today, it announced a new superthin sound technology that can turn any surface inside your car into “invisible” speakers.

Known as the Thin Actuator Sound Solution (TASS), the tech forgoes all the bulky components that make up traditional speakers — drivers, magnets, cones, coils — in favor of what LG Display calls “film-type exciter technology” that comes in passport-sized panels (150mm x 90mm x 2.5mm) that can be embedded into a car’s interior, such as dashboards, headliners, pillars, and headrests.

The company says that the thin TASS can vibrate off of almost any surface inside the car to create sound. And at just 30% of the weight and 10% of the thickness of conventional car speakers, this can open up all kinds of options for placement, which will lead to a more immersive sound experience, while also freeing up space inside door panels and other traditional automotive speaker placement locations.

“We have transformed the conventionally heavy and bulky speaker into a high-quality ‘invisible’ sound solution by using our cutting-edge technology to elevate space, design, and eco-friendly factors and provide a next-level sound experience like none before,” said Yeo Chun-ho, vice president and head of the business development division at LG Display.

The company isn’t alone in the race to rethink in-car audio. In 2021, Resonado Labs announced that its flat core speaker tech, which also reduces the size of conventional speakers, would be used in vehicles, including Airstream trailers.

LG Display is expecting to commercialize the TASS tech early next year, but if you’re among the nerdy hordes attending CES 2023 in January, you can get a sneak peek of the tech, for which the company has just won a CES 2023 Innovation Award in the In-Vehicle Entertainment & Safety category.

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.

After giving us a sneak peek at its new 2022 soundbar lineup at CES, LG has finally released these home theater speakers. The prices start at $400 for the entry level LG S65Q 3.1-channel model, and then head sharply upward, topping out at $1,800 for its LG S95QR flagship soundbar -- a 9.1.5-channel, Dolby Atmos-capable multi-speaker beast. All six new models, (S95QR, S90QY, S80QR, S80QY, S75Q, and S65Q) are available now on LG.com, as well as from select retailers like Amazon.com.

All of the new models offer a different set of features, but regardless of how much you spend, LG has included some common characteristics. Hi-res audio, with tuning by Meridian, is the key feature that unites these speakers. Soundbars tend to place an emphasis on delivering good TV sound, but LG has decided to put an equal emphasis on how these speakers work with music.

KEF LS60 bring wireless hi-res audio to floor-standing speakers

KEF LS60 Wireless Speakers seen in Titanium Grey.

KEF's LS50 Wireless and LS50 Wireless II speakers set a very high bar for what you can expect from a set of powered, wireless speakers, and now the British audio brand has its sights set on doing the same thing for larger-format floor-standing speakers with the LS60 Wireless. Priced at $7,000 per pair, they come in three distinct colors: Royal Blue, Mineral White, and Titanium Grey. They're available for pre-order starting May 12, with shipping beginning in June 2022.

Many of the same integrated capabilities that made the LS50/LS50 II so popular are also found in the LS60 Wireless, like KEF's signature Uni-Q drivers, as well as support for Wi-Fi, Bluetooth, HDMI eARC, and optical, coaxial, and RCA connections. There's also app- and remote-based control that includes easy access to subscription streaming services like Amazon Music, Qobuz, and Deezer.
